12 Different types of Door lock

Door locks are the devices that keep your home secure by controlling who can enter and when. They're basically the guardians of your personal space, standing between you and anyone who shouldn't be there. Most of us don't think much about our locks until something goes wrong, but they're actually doing important work every single day. A good door lock enhances home security by creating that first barrier against break ins, giving you control over access to your space, and letting you sleep peacefully knowing your family and belongings are protected. Beyond just stopping burglars, locks provide privacy when you need it, help you manage who can access different parts of your home, and often play a role in meeting insurance requirements.

There are 12 main types of door locks, and each one serves different needs depending on your situation. Deadbolt locks are the heavy hitters of home security, using thick metal bolts that slide deep into your door frame and stay put until you turn the key. Knob locks are those familiar round locks you probably grew up with, though they're not great on their own for security. Lever handle locks work like knob locks but with a handle instead of a round knob, making them easier for people with mobility issues to use. Cam locks are those simple locks you see on mailboxes and cabinets that just need a quarter turn to secure. Mortise locks are the robust systems that fit into a pocket carved right into your door edge and often combine several locking mechanisms together. Smart locks bring technology into the mix, letting you unlock your door with your phone or automatically when you get home. Keypad locks let you punch in a code instead of fumbling for keys in the dark. Padlocks are the portable option you can take anywhere and use on gates, sheds, or storage units. Chain locks give you that extra bit of security by letting you crack the door open while keeping it connected to the frame. Rim locks mount right on the surface of your door rather than being built into it. Euro cylinder locks are popular across Europe and make it easy to change just the cylinder part when you need new keys. Magnetic locks use powerful electromagnets to hold doors shut and are common in office buildings and high security areas.

Choosing the right door lock for your home isn't just about picking the most expensive one or the one that looks coolest. You need to think about your specific situation and what you're trying to accomplish. If you live in a quiet suburban neighbourhood, your security needs are probably different from someone in a busy urban area. Consider who's going to be using these locks every day. If you have elderly parents living with you or family members with arthritis, those easy to turn lever handles might be much more practical than traditional knobs. Families with kids often love keypad locks because there are no keys for children to lose on the playground. Think about your lifestyle too. If you're always coming home with your hands full of groceries or if you frequently have guests over, a smart lock that unlocks automatically or lets you give out temporary codes might be worth the investment. Don't forget about the practical stuff either. Some locks need batteries that you'll have to replace, others might need professional installation, and certain types work better in harsh weather than others. The appearance matters too since your locks are part of your home's overall look. Finally, consider the long term costs and convenience. That cheap lock might seem like a good deal now, but if it breaks in two years or doesn't provide the security you need, you'll end up spending more money and dealing with more hassle down the road.

‍

Deadbolt Lock

A deadbolt lock is the security champion of the door lock world, using a solid metal bolt that shoots straight into your door frame and stays there until you tell it to move. Unlike other locks that might have springs or moving parts that can be manipulated, a deadbolt is refreshingly straightforward. When it's locked, that thick metal bolt extends about an inch into your door frame, creating a solid connection that's really hard to break. You'll find deadbolts in single cylinder versions where you use a key from outside and a thumb turn from inside, or double cylinder types that need a key from both sides for maximum security.

The magic happens when you put your key in and turn it. Inside the cylinder, there are pins that need to line up just right for the lock to work, and your key has the exact cuts needed to push those pins into position. When everything aligns, the cylinder can rotate, which moves a cam or tailpiece that's connected to the bolt mechanism. This action pushes that solid metal deadbolt straight out of the lock housing and into the hole in your door frame's strike plate. To unlock it, you just turn your key the other way, and the bolt slides back into the lock. It's beautifully simple, which is part of what makes it so reliable. There are no springs to wear out or complex mechanisms to jam up.

Installing a deadbolt isn't rocket science, but it does require some precision and the right tools. You need to drill a large hole through the face of your door for the cylinder, usually about 2 1/8 inches across, and then a smaller hole from the edge of the door to meet up with that cylinder hole for the bolt mechanism. The tricky part is getting everything lined up perfectly so the bolt slides smoothly into the strike plate opening. Speaking of the strike plate, that needs to be mortised into your door frame with a hole drilled deep enough for the bolt to extend fully. The real security comes from using long screws, at least 3 inches, that go through the strike plate and into the solid wood framing behind your door trim. Your door and frame need to be in good shape and properly aligned, or you'll have trouble with the bolt binding or not extending fully.

Deadbolts are the go to choice for exterior doors where security matters most. You'll find them on front doors, back doors, side entrances, and pretty much any door that leads from the outside into your home. Many building codes actually require deadbolts on primary entrance doors, and insurance companies often give better rates when you have them installed. They're also popular on doors between attached garages and the house, since garages can be easy targets for burglars. Some people install deadbolts on basement doors, storage room doors, or even interior doors where they want extra security for valuable items. In small businesses, deadbolts often secure entrance doors, storage areas, and offices after hours. While they're primarily used on doors, you can also find deadbolt mechanisms in some high security applications like safes and vault doors.

‍

Knob Lock

A knob lock is that familiar round door handle that most of us have been using our whole lives without giving it much thought. It's the classic door hardware where you turn a round knob to open the door, and there's usually some way to lock it from the inside with a little button or turn mechanism. These locks have a spring loaded latch that automatically shoots out when you close the door and pulls back when you turn the knob. They're everywhere in homes because they're simple, cheap, and do the basic job of keeping doors closed during everyday use. While they might not win any security awards, knob locks are the workhorses of interior doors and often serve as the convenient daily use lock on exterior doors alongside more serious security hardware.

The way these locks work is refreshingly simple, which is probably why they've been around for so long. Every time you close a door with a knob lock, that spring loaded latch bolt gets pushed back by the strike plate as the door closes, then immediately springs forward into the opening to hold everything in place. When you want to open the door, you just turn the knob, which rotates an internal spindle that pulls the latch bolt back so the door can swing open. The locking part usually involves a button on the inside knob that you push to prevent the outside knob from working, or sometimes there's a small turn mechanism. If your knob lock has a keyed cylinder on the outside, you can lock and unlock it with a key, though many interior knob locks just have that simple privacy function.

Installing a knob lock is probably one of the easiest lock jobs you can tackle, mainly because most doors already have the right holes drilled for them. You need that standard 2 1/8 inch hole through the door face where the main lock body sits, plus a smaller hole from the door edge that connects to the main hole for the latch mechanism. The strike plate gets a shallow cut into the door frame since these latches don't stick out very far. Most knob locks come with paper templates that show you exactly where everything goes, and the instructions are usually pretty straightforward. The main thing is making sure everything lines up so the latch slides smoothly into the strike plate when you close the door. Getting the door gap right is important too, so the lock doesn't bind up when you try to use it.

You'll find knob locks all over residential properties, though they rarely stand alone on exterior doors these days. They're perfect for interior doors like bedrooms, bathrooms, offices, and closets where you want basic privacy or just need to keep the door latched shut. Most people are comfortable with knob locks because we all learned how to use them as kids, so there's no learning curve when you encounter one. On exterior doors, knob locks often team up with deadbolts, handling the everyday convenience while the deadbolt does the heavy security lifting. They also show up on secondary exterior doors like basement entrances, side doors, or doors leading to enclosed porches where maximum security isn't the top priority but you still want some control over access.

‍

Lever Handle Lock

A lever handle lock is basically a knob lock's more accessible cousin, doing the same job but with a handle you push down instead of a knob you have to grip and twist. This might seem like a small change, but it makes a world of difference for anyone who struggles with traditional knobs. Whether you're dealing with arthritis, carrying an armload of groceries, or just want easier operation, that simple push down motion is so much more manageable than trying to get a good grip on a round knob and twist it. The internal mechanism is virtually identical to a knob lock, with the same spring loaded latch system, but the lever handle makes everything more user friendly.

The way lever handle locks operate is exactly like knob locks, just with a different trigger mechanism. When you push down on that lever handle, it rotates the same internal spindle that pulls the latch bolt back into the lock housing so you can open the door. Let go of the handle, and the latch springs back out to hold the door closed. The beauty of the lever design is that you can operate it with your elbow, forearm, or even a gentle push with your hip if your hands are full. The locking mechanisms work the same way too, with options for keyed cylinders, push button locks, or turn mechanisms depending on what level of security or privacy you need. Some handles spring back to horizontal automatically, while others might stay down until you push them back up.

Installing a lever handle lock follows the same process as installing a knob lock since they use identical door preparations and strike plate setups. You still need that 2 1/8 inch hole through the door and the connecting hole from the edge for the latch. The one thing to keep in mind is that lever handles create different forces on the door and lock mechanism because of the leverage involved, so you want to make sure your door is solid enough to handle the stress. The strike plate goes in exactly the same way, mortised into the door frame and secured with screws. If you're swapping out an existing knob lock for a lever handle, it's usually a straightforward replacement since all the hole sizes and spacing are standardised.

Lever handle locks are practically mandatory in commercial buildings these days because of accessibility requirements, and for good reason. They make life easier for people using wheelchairs, carrying equipment, or dealing with any kind of mobility challenge. In office buildings, schools, and hospitals, you'll see lever handles everywhere because they're so much more practical than knobs. For homes, they're becoming increasingly popular as people discover how convenient they are. They're especially great on doors you use frequently with your hands full, like the door between your house and garage, or interior doors in busy areas like laundry rooms and pantries. Many families install them throughout their homes when they have elderly members or anyone dealing with hand mobility issues, and once you get used to the convenience, it's hard to go back to struggling with traditional knobs.

‍

Cam Lock

A cam lock is one of those simple, no fuss mechanisms that you probably use all the time without even thinking about it. It's basically a cylinder with a flat metal arm on the back that does all the work. You stick your key in, give it a quick quarter turn, and that little arm either swings into position to lock something or moves out of the way to unlock it. These locks are everywhere because they're cheap, easy to work with, and perfect for situations where you need basic security without any fancy bells and whistles. They might not stop a determined thief, but they're great for keeping honest people honest and preventing casual tampering with your stuff.

The beauty of cam locks is in their simplicity. When you put your key in and turn it, you're rotating the entire cylinder, and that flat cam arm on the back turns right along with it. Depending on the position of the cam, it either blocks whatever you're trying to secure or gets out of the way so you can access it. Picture a cabinet door where the cam swings across to prevent the door from opening when locked, then rotates clear when you unlock it. Most cam locks only need a 90 degree turn to go from locked to unlocked, so it's quick and easy to operate. Some versions spring back to their starting position when you pull the key out, while others stay wherever you left them until you turn the key again.

Installing a cam lock is about as straightforward as lock installation gets. In most cases, you just drill one hole through whatever you're trying to secure, push the lock cylinder through from the front, and fasten it down with a nut or retaining clip on the back. The hole is usually a standard size, often around 5/8 or 7/8 inches depending on the lock you choose. The main thing to watch out for is making sure the material is the right thickness for your particular lock and that there's enough room behind for the cam to rotate freely. You also want to think about what the cam is going to engage with when it's in the locked position, since that's what actually provides the security.

You encounter cam locks constantly in everyday life, often in places where you need to keep things secure but don't want to deal with heavy duty hardware. Mailboxes probably have cam locks, along with filing cabinets, desk drawers, and tool boxes. They're popular in RVs and boats where you have lots of small compartments that need securing but weight and space are at a premium. Around the garage or workshop, cam locks are perfect for storage cabinets, especially ones made from thin plywood or metal where you can't fit a more substantial lock. Vending machines use them, utility boxes have them, and you'll find them on employee lockers and equipment panels in commercial settings. They're the go to choice anytime you have thin material that needs basic security without the complexity or cost of more sophisticated locking systems.

‍

Mortise Lock

A mortise lock is the serious, professional grade lock that means business. Unlike locks that just bolt onto the surface of your door, a mortise lock lives in a rectangular pocket carved right into the edge of the door itself. These are the locks you find in commercial buildings, upscale homes, and anywhere that people are serious about both security and durability. They're built like pieces of machinery, with solid metal construction and multiple moving parts all housed in that rectangular case. When you see a mortise lock, you know someone invested in quality hardware that's designed to work smoothly for decades of heavy use.

The way mortise locks work is more sophisticated than your average door lock because they usually do multiple jobs at once. Most mortise locks have both a spring loaded latch that automatically holds the door closed and a separate deadbolt for serious security. When you turn the door handle or lever, you're operating just the latch mechanism so you can open and close the door normally throughout the day. When you want real security, you use the key or thumb turn to extend that deadbolt deep into the door frame. Some mortise locks get even fancier, with indicator buttons that show you whether the deadbolt is engaged or automatic functions that lock the door when you close it. The key typically controls everything, giving you the ability to manage both the everyday convenience features and the security functions.

Installing a mortise lock is definitely a step up in complexity from simpler locks because you're essentially doing precision carpentry work on your door. You have to carve out that rectangular mortise pocket in the door edge, and it needs to be exactly the right size and depth for the lock body to fit perfectly. Get the measurements wrong, and you're probably looking at buying a new door. You'll also need to drill holes for the cylinder and handles, plus cut recesses for the metal faceplates that sit flush with the door surface. This isn't a job for hollow core doors or flimsy construction since the door needs to be substantial enough to handle having a big chunk carved out of it. Many people opt for professional installation on mortise locks because the carpentry work is unforgiving and mistakes are expensive.

Mortise locks are the standard in commercial buildings where doors get opened and closed hundreds of times a day and need to keep working year after year. Office buildings, schools, hospitals, and retail spaces rely on mortise locks because they can handle the abuse and still operate smoothly. In residential settings, you'll find them in higher end homes, condos, and apartment buildings where the initial investment in quality hardware pays off in long term reliability. Many older homes, especially those built when craftsmanship was more important than cost cutting, came with mortise locks that are still working perfectly decades later. They're particularly popular on main entrance doors, security sensitive areas, and anywhere that building codes or insurance requirements call for commercial grade hardware.

‍

Smart Lock

A smart lock is what happens when traditional door hardware meets modern technology, and the result is pretty amazing once you get used to it. These locks connect to your smartphone or home WiFi network, letting you control your door in ways that go way beyond just turning a key. You might unlock your door automatically when you get home from work, get a notification on your phone when your teenager comes home from school, or give the repair person access while you're still at the office. Smart locks usually combine electronic components like tiny motors and sensors with regular mechanical parts, so you get all the high tech convenience while still having a reliable physical lock doing the actual securing.

The way smart locks work varies depending on what model you choose, but they all replace the simple act of turning a key with something much more sophisticated. Instead of fumbling for your keys, you might just tap your phone, enter a code on a touchscreen, or even have the door unlock automatically when it detects your phone getting close. Inside the lock, there's a small computer that checks whether you're authorised to enter, then activates a motor that moves the deadbolt to unlock your door. Many smart locks can also lock themselves after you leave or after a certain amount of time passes, and they can send you notifications about what's happening with your door even when you're miles away. The electronic parts communicate with your phone or home network to give you control and information that regular locks just can't provide.

Smart locks offer some interesting security advantages, though they do come with their own set of considerations. On the good side, you can monitor who's coming and going even when you're not home, and you'll get instant notifications if someone enters unexpectedly. You can easily give temporary access to guests, house sitters, or service people and then revoke it when you no longer need them to have access. Many smart locks keep detailed records of when the door was locked or unlocked and by whom, which can be really valuable information. However, smart locks do depend on batteries and electronic components that could potentially fail at inconvenient times. They might also be targets for tech savvy intruders who know how to exploit electronic vulnerabilities. Most good smart locks include backup features like physical key overrides and plenty of warning when batteries are getting low to help address these concerns.

Installing a smart lock can be anywhere from pretty straightforward to somewhat complex, depending on what you're replacing and how fancy your new lock is. Many smart locks are designed to fit right where your existing deadbolt was, using the same holes and door setup, which makes installation similar to swapping out any other lock. However, some models might need additional wiring for power or network connections, especially if you're integrating them with other home automation systems. You'll need to think about power requirements since most smart locks run on batteries that you'll need to replace periodically. The locks tend to be heavier than traditional ones because of all the electronics, so make sure your door can handle the extra weight. WiFi signal strength at your front door matters too, since many smart locks need a good internet connection to work properly.

Smart locks are really taking off in modern homes, especially among people who love technology or just appreciate the convenience factor. They're fantastic for busy families where people are coming and going at all hours and nobody wants to deal with making extra keys or wondering whether the door got locked. Parents love being able to see when their kids get home from school, and people who travel frequently appreciate being able to check on their home security from anywhere. They're also great for vacation rental properties where you need to give access to different guests without meeting them in person. Urban homeowners often like the enhanced security monitoring and the peace of mind that comes with being able to verify their door is locked while they're at work. Plus, if you're already into smart home technology, having your locks work together with your security cameras, lights, and alarm systems can create a pretty sophisticated home security setup.

‍

Keypad Lock

A keypad lock is your ticket to freedom from the eternal struggle with keys, letting you punch in a numeric code instead of fumbling around trying to find the right key in the dark. These locks have a number pad right on the front where you enter your personal code to unlock the door. No more digging through your purse or pockets, no more getting locked out because you forgot your keys, and no more making a dozen copies for everyone in the family. Keypad locks come in mechanical versions that use your code input to physically move internal parts, and electronic versions that use the code to trigger motors that operate the lock. Both types give you that wonderful feeling of never having to worry about keys again.

How these locks work depends on whether you've got a mechanical or electronic version, but both rely on you knowing the secret number combination. With mechanical keypad locks, each button you press moves specific parts inside the lock into position, and when you've entered the complete correct code, everything lines up just right to let the lock mechanism operate. These mechanical versions are pretty bulletproof since they don't need batteries and there's no electronics to go wrong. Electronic keypad locks take your code input and use it to control motors or solenoids that actually move the deadbolt for you. The electronic versions often have cool extra features like different codes for different family members, temporary codes for house guests, and logs that show you when people came and went.

Keypad locks solve a lot of the problems that come with traditional keys while creating a few new things to think about. On the plus side, there are no keys to lose, no copies to make, and no worries about someone finding your hidden spare key. You can easily change the access code if you think it's been compromised, and many keypad locks let you set up multiple codes so different family members or employees can have their own. You can create temporary codes for the dog walker or house cleaner that automatically stop working after a certain time. However, people might be able to watch you enter your code, and over time the most used numbers might show wear patterns that give clues about your combination. Electronic versions need battery changes, and weather can sometimes affect the keypad operation. Good keypad locks address these issues with features like code scrambling options, weather sealing, and plenty of advance warning when batteries are getting low.

Installing a keypad lock follows the same basic process as installing most deadbolt locks, though there are a few extra considerations because of the keypad mechanism. You'll need the standard door holes for the lock body and bolt mechanism, just like any deadbolt installation. The main difference is that keypad locks are usually heavier than regular locks because of all the keypad hardware and any electronic components, so you want to make sure your door is solid enough to support the extra weight. Electronic keypad locks need easy battery access for maintenance, so think about how convenient it'll be to change batteries when the time comes. Weather protection is more important than with regular locks since the keypad is more exposed to rain and temperature changes than a simple key cylinder would be.

Keypad locks are incredibly popular with families who are tired of dealing with lost keys and locked out kids. They're perfect for households where everyone comes and goes at different times or where you frequently have visitors who need access. Many parents love them because they solve the problem of kids losing house keys and eliminate the need to hide spare keys around the property where burglars might find them. Small businesses often use keypad locks on employee entrances or storage rooms because they can easily add new employee codes or remove codes when people leave without having to rekey the entire system. Vacation rental owners love keypad locks because they can give guests the access code without having to meet them in person, then change the code between different renters. They're also great on secondary doors like garage entrances, back doors, or basement doors where you might not always have your regular keys with you.

‍

Padlock

A padlock is that completely portable lock that you can take anywhere and use on just about anything that needs securing. It's the ultimate flexible security solution because it's not permanently attached to any particular door or object. The whole lock is self contained in a metal body with that distinctive U shaped shackle that opens and closes to grab onto whatever you're trying to secure. You can toss a padlock in your toolbox, keep one in your car for emergencies, or use the same lock on your storage unit today and your garden gate tomorrow. They've been around forever because they solve the fundamental problem of needing security in places where you can't install a permanent lock.

How padlocks work is refreshingly simple, which is probably why they've stayed basically the same for hundreds of years. You stick your key in the bottom of the lock body, turn it, and the shackle pops open so you can position it around whatever needs securing. Close the shackle and it automatically clicks back into the locked position, holding whatever you've captured until you unlock it again with the key. Combination padlocks work similarly, except you dial in the right number sequence instead of using a key to release the shackle mechanism. Inside the lock body, there's either a pin tumbler system like in house locks or a simpler mechanism that just needs to recognise your key or combination. The shackle is usually made of hardened steel to resist cutting attempts, and better padlocks have shackles that lock into the body at both ends rather than just one.

The security benefits of padlocks come mainly from their versatility and the fact that they can be used in situations where other types of locks just won't work. You can secure things that don't have built in locking mechanisms, like chains across driveways or hasps on storage containers. Good padlocks use hardened components that resist cutting and drilling, and they can often provide better security than the built in locks on many storage units or garden sheds. Since padlocks are removable, you can take them with you when you're not using them, which eliminates the possibility of someone working on defeating the lock while you're away. However, padlocks are only as secure as whatever they're attached to, and they can be vulnerable to bolt cutters or other cutting tools if someone really wants to get through them.

Installing a padlock usually means setting up whatever the lock is going to attach to rather than installing the lock itself. For gates or doors, you might need to mount a hasp, which is basically a hinged metal strap that folds over a loop where the padlock shackle goes. Storage containers might need eye bolts or metal loops welded or bolted in place. The important thing is making sure whatever you're attaching the padlock to is stronger than the lock itself, because there's no point in having a high security padlock if it's attached to flimsy hardware that can be easily broken. You want mounting screws or bolts that go into solid material, not just surface mounting that someone could pry off easily.

Padlocks show up everywhere in our daily lives because they're so versatile and practical. Storage units almost always use padlocks since renters can bring their own locks and take them when they move out. Garden sheds, toolboxes, and workshop cabinets are natural fits for padlocks, especially when you might want to move the lock to different things over time. Many people use padlocks to secure gates, whether it's a simple garden gate or a more substantial entrance to a business or construction site. They're popular for securing bicycles, motorcycles, and trailers since you can take the lock with you when you're not using those vehicles. Schools and gyms rely on padlocks for lockers because they can be easily changed when students graduate or memberships change. Construction sites often use padlocks to secure tool storage, electrical panels, and equipment that needs to be accessible to workers but protected from theft.

‍

Chain Lock

A chain lock is that simple but clever device that lets you crack your door open just enough to see who's there and have a conversation, but not enough for them to push their way inside. You've definitely seen these in hotels or apartment buildings, where they give you a way to answer the door safely without fully opening it to strangers. The whole system is just a short length of sturdy chain connected to a sliding bracket that moves along a track on your door, with the other end of the chain bolted to your door frame. When you slide that bracket to the end of its track, the chain becomes tight and prevents your door from opening more than a few inches, no matter how hard someone pushes from the outside.

The operation couldn't be more straightforward since it's just basic physics at work. When you want to use the chain lock, you slide the bracket along its track until the chain gets tight, which physically limits how far your door can swing open. The chain itself takes all the force if someone tries to push the door open further, and it transfers that force to both the door and frame mounting points. To disengage it, you just slide the bracket back toward the hinged end of the door, creating slack in the chain so the door can open normally. Some chain locks have a little spring or detent that helps keep the bracket in the engaged position so it doesn't slide around accidentally, but most rely on friction or gravity to stay put.

Chain locks provide a specific kind of security that's really about controlled access rather than maximum protection. The big advantage is being able to interact with visitors while maintaining a physical barrier that prevents them from forcing their way inside. This is especially valuable when you're not expecting anyone or when someone you don't recognise comes to your door. Chain locks also give you peace of mind if you're home alone or if you're concerned about your safety when answering the door. They're particularly helpful for elderly people or anyone who might be more vulnerable to home invasion attempts. However, it's important to understand that chain locks aren't designed to stop a really determined intruder with tools or someone willing to use significant force. They work best as an additional security measure alongside your regular door locks.

Installing a chain lock is one of the simpler lock related projects you can tackle, requiring just basic tools and some careful positioning. The track gets screwed directly to your door, usually at about shoulder height where it's convenient to reach but not so obvious that it draws attention. You want those screws going into solid wood rather than just the door skin, especially since the track will experience stress when the chain is engaged. The chain anchor mounts to your door frame at a position that lets the chain become taut when the bracket is slid to the end of the track. Getting the positioning right is important because if the chain is too long or too short, it won't provide the right amount of door opening control.

Chain locks are most common on apartment doors, hotel rooms, and homes where residents want that extra bit of security when answering the door. They're particularly popular with people who live alone, elderly residents, or anyone who's had experiences that make them more cautious about opening doors to strangers. Many urban dwellers appreciate chain locks because they provide a way to interact with delivery people, maintenance workers, or unexpected visitors without feeling vulnerable. Parents sometimes like chain locks because they prevent small children from opening the door fully, even if the child figures out how to unlock the main door lock. They're also useful in situations where you might want to leave the door slightly open for ventilation while still maintaining some security, though this should obviously be done carefully and only when someone is home and alert.

‍

Rim Lock

A rim lock is a lock that sits right on the inside surface of your door instead of being buried deep inside it. You can actually see this type of lock mounted on your door when you look at it from inside your home. We fit rim locks when people want extra security but don't want to make big changes to their existing door setup.

When you use a rim lock, it works with a simple spring system that clicks into place. From outside, you put your key in and turn it, which pulls back the metal bolt so your door opens. From inside, you can turn a little knob instead of using a key. The clever thing about rim locks is they snap back into the locked position all by themselves when you close the door. This means you don't have to remember to lock up every time you come home.

These locks give you solid protection because they spread out the pressure if someone tries to force your door open. The whole lock body is attached firmly to your door, so it takes more effort to break through than you might expect. Many of our customers like rim locks because burglars can see them clearly from outside, which often makes them think twice about trying to get in. What's even better is that rim locks work completely separately from any other locks you already have on your door.

When we install a rim lock, we mount the main part to the inside of your door and drill one hole for the key cylinder to go through to the outside. Your door needs to be thick enough, usually at least 35mm, so the cylinder fits properly without any problems. We also check that your door frame is strong enough to handle the extra weight and pressure without causing any damage. Most of the time, it takes us about 30 to 45 minutes to get everything fitted and working smoothly.

People choose rim locks most often for their front doors, back doors, and security gates where they want that extra layer of protection. They work really well on older houses where the doors are built in a way that makes other types of locks tricky to install. Many landlords go for rim locks on rental properties because they boost security without making permanent changes that might affect the original door. We also see lots of businesses using rim locks for their after-hours security, especially on doors that get heavy use during the day.

Euro Cylinder Lock

A euro cylinder lock uses a neat little cylinder that slots into your door handles, deadbolts, and other door hardware. This system started in Europe but has become really popular here in Australia because it works with so many different types of doors and security setups. We work with euro cylinders that come in different sizes to match whatever thickness your door happens to be.

The way a euro cylinder lock works is through tiny pins and springs inside the cylinder that have to line up just right when you put your key in. When you turn your key, the whole cylinder spins around and that movement operates whatever locking mechanism is connected to it, whether that's your door handle or a separate deadbolt. The pins and springs inside are precisely made so only your specific key will make everything align properly. The lock clicks into place automatically when you close your door, and you need your key to open it from outside.

Euro cylinder locks give you really good security because they're engineered so precisely and have built-in features that stop people from picking or bumping them open. Many of the newer models have special pins that resist drilling, technology that prevents bump keys from working, and extra-strong construction throughout. We recommend these locks because they stand up well against the most common ways people try to break in, like picking, bumping, and drilling. Because they follow standard measurements, we can swap out or upgrade your locks quickly without having to change all your door hardware.

When we install euro cylinder locks, we need to measure everything very carefully to make sure the cylinder fits perfectly in your existing door setup. We measure how thick your door is, how far it is from the edge of your door to the centre of the hole, and how high your handle sits. We need to get to both sides of your door while we're working, but the whole job usually only takes us 15 to 30 minutes per lock. The good news is that most modern door handles and deadbolts are already set up to take euro cylinders without any modifications.

We fit euro cylinder locks in homes, apartments, and business buildings where people want dependable security that's easy to maintain over time. These locks work brilliantly in systems where multiple locking points operate together, which we often set up on French doors and sliding doors. Property managers really appreciate euro cylinder locks for rental properties because they can get individual units rekeyed easily without replacing all the hardware. We also recommend these locks for businesses that need to give different groups of employees access to different areas.

Magnetic Lock

A magnetic lock is basically an electronic lock that uses really strong magnets to hold your door shut tight. Unlike regular locks that have lots of moving bits and pieces, magnetic locks are pretty simple because they don't have any parts that actually move around. We put these in when people want a modern security setup that they can control with electronics and hook up to fancy access systems.

Here's how these clever locks actually work. There are two metal plates, and when you switch on the power, one of them becomes a super strong electromagnet that grabs onto the other plate like you wouldn't believe. We mount one plate on your door frame with all the magnetic stuff inside it, and the other plate goes on your actual door. When the power is on, these two plates stick together with incredible force, sometimes holding with more than 1,200 pounds of pull. That's like trying to separate two pieces of metal that have a small car hanging off them. To get your door open, you have to cut the power to break that magnetic grip, which you can do with things like swipe cards, remote controls, or just pressing an exit button.

The security you get from magnetic locks is really impressive because once they're powered up and holding, there's virtually no way someone can force them open. The magnetic pull is so incredibly strong that even the strongest person can't yank the door open against it. What's also nice about them is they work completely silently, so you don't get those clicking and clunking sounds that regular locks make. We find they're perfect for places where you want to keep track of who's coming and going because you can connect them to computer systems that log every time someone uses them.

When we install magnetic locks, we need to run electrical cables to power the whole system, which means connecting them to your building's main power or setting up a separate power box. We carefully mount the magnetic plate to your door frame and the metal plate to your door, making sure they line up perfectly so you get the strongest possible hold. You also need some way to release the magnetic grip when you want to open the door, whether that's card readers, push buttons, or other electronic gadgets. Depending on how complicated your access system needs to be, we can usually get everything installed and working in about an hour.

Most people use magnetic locks in office buildings, schools, hospitals, and other business places where controlling who gets in electronically really matters. They work brilliantly on glass doors and really heavy doors where regular locks might not be strong enough or might break down from all the use they get. Lots of businesses go for magnetic locks in areas where they want to control access during work hours but need people to be able to get out quickly in emergencies. We're also seeing more residential apartment buildings using them with security systems where people want keyless entry and the ability to control their doors remotely.

How to choose the right lock for your home?

Picking the right lock for your home really comes down to a few things that make a big difference in how well it works for you day to day. The type of door you have is probably the biggest factor because some locks just don't work well with certain materials or door thicknesses. If you've got solid timber doors, you're in luck because pretty much any lock will work great. But if you have glass doors or really thin doors, you might need to go with specific types like magnetic locks or ones that mount on the surface.

Where your door is located around your home also changes what kind of lock makes the most sense. Your front door is probably going to need something strong and visible that puts off potential burglars and can handle being used multiple times every day. Back doors and side entrances might need different approaches depending on how much you actually use them and whether people walking by can easily see them. Doors inside your house usually don't need heavy security but you might want something that looks good and doesn't get in the way when people are moving around your home.

Think about how much security you actually need too. Some areas of your home might need multiple locks, electronic controls, or locks with special features that stop people from picking or drilling them. For most regular home security, good quality mechanical locks give you solid protection without being overly complicated. If you've got expensive stuff or important documents in certain areas, you might want locks that you can monitor or control electronically.

How often you use each door really affects what kind of lock will work best for you. Doors that get opened and closed dozens of times every day need locks that are built tough and won't wear out quickly from all that use. Doors you hardly ever open can focus more on security features rather than smooth daily operation. Also think about whether lots of different people need access and how often you might need to change who can get in.

Which locks are best for different door types?

Each type of door works best with specific locks that match what the door is made of and how you use it.

• Cabinet/Furniture: Cam locks work perfectly for cabinets and furniture because they sit flush inside the door and don't stick out to catch on things. These locks use a simple cam mechanism that rotates to secure the door from inside, making them ideal for filing cabinets, desk drawers, and storage units where you want security that doesn't get in the way.
• Interior Wooden Doors: Knob and lever handle locks are perfect for wooden doors inside your home because they're easy to use every day and come in styles that look good with timber. These locks combine the door handle with the locking mechanism, so you get convenience and security without having to install separate components.
• External Residential: Deadbolts and smart locks give you the strongest protection for your front and back doors where security really matters. Deadbolts provide solid mechanical security that's hard to force, while smart locks let you control access with keypads, apps, or fingerprints instead of traditional keys.
• Metal Doors: Mortise and euro cylinder locks work brilliantly with metal doors because they're built tough enough to handle the strength and weight of metal construction. These locks fit securely into metal frames and can cope with the heavy daily use that metal doors often get in commercial or high-security situations.
• Frameless Glass: Magnetic locks are the only real option for frameless glass doors because they don't need holes drilled or hardware mounted that could crack or weaken the glass. The magnetic system holds everything together without putting any stress on the glass panels themselves.
• Sheds and Gates: Padlocks and chain locks give you flexible security for outdoor structures that don't have built-in locking systems. You can move these locks around between different gates or storage areas as needed, and they're tough enough to handle weather and outdoor conditions year after year.

Which locks are most resistant to picking?

Lock picking happens when someone uses special tools to mess around with the inside parts of your lock without having the right key. Some locks are much better at stopping these sneaky techniques because of how they're built inside.

• Deadbolts: Really good deadbolts with anti-pick bits and tough steel parts make it super hard for anyone to fiddle with the lock mechanism. The way they're built so solidly and precisely means there isn't enough wiggle room for picking tools to do their thing properly.
• Mortise Locks with Anti-Pick Pins: These locks have specially shaped pins and springs that get all jammed up when someone tries to pick them. The anti-pick pins basically mess with the person trying to break in by giving them confusing signals that make it almost impossible to figure out when each pin is sitting right.
• Euro Cylinder (3-Star Versions): The top-rated euro cylinders pack in loads of security features like anti-pick pins, anti-bump tech, and really tough materials. These 3-star ones meet strict European security rules and fight off not just picking but other sneaky methods like bumping and drilling too.
• Smart Locks with No Mechanical Keyhole: Loads of modern smart locks get rid of the old-fashioned keyhole completely and only work with electronic stuff like keypads, fingerprints, or your phone. When there's no keyhole at all, there's literally nothing for someone to pick, which makes these locks basically impossible to pick using old-school methods.
• Cam Locks with Tubular Keys: The way the pins are arranged in a circle in tubular cam locks means you need special round lock picks that most people trying to break in just don't have lying around. The weird key design and the way the inside mechanism works make these locks much tougher to pick than your regular everyday locks.

What are the most cost-effective security locks?

Euro cylinder locks offer the best value for money when it comes to security locks. You get excellent security features, durability, and the ability to easily upgrade or rekey without replacing all your door hardware. They work with most modern doors and provide professional-grade protection at a reasonable price point that fits most home security budgets.
