What to Know About Magnetic Locks

An electromagnetic lock is a security device that keeps doors closed using magnetic force. Most people know these locks by different names - you might hear them called "maglock," "fail-safe magnetic lock," or "electromagnetic door lock." All these names describe the same type of locking system that works through magnetism.

When you look at a magnetic lock, you'll see it has two main parts. The electromagnet sits on the door frame, and the armature plate goes on the door itself. These two pieces work together to create the lock. When power flows to the electromagnet, it pulls the metal armature plate towards it with incredible strength.

Here's how it works in simple terms. The electromagnet turns on when it gets electricity, creating a magnetic field. This field grabs onto the armature plate and holds it tight against the electromagnet. The magnetic pull is so strong that it can hold with 600 to 1,200 pounds of force. When you turn off the power or press a release button, the magnetism stops and the door opens easily.

You'll find magnetic locks in many commercial buildings because they're reliable and strong. Office buildings use them for main entrances and secure areas. Shops and warehouses like them because they don't wear out like regular locks do. Even residential security systems use magnetic locks, especially in apartment complexes and homes where people want electronic access control. Places that need tight security, like server rooms or laboratories, often choose magnetic locks because they work well with card readers and other access systems.

These locks are perfect for doors that need to stay secure most of the time but open quickly when needed. Fire exits commonly use magnetic locks because they automatically unlock when the fire alarm goes off. This safety feature makes them ideal for buildings where people need to get out fast during emergencies.

Most magnetic locks last between 10 and 15 years with proper care. They don't have many moving parts that break down, so they're quite reliable. The electronic parts rarely fail, and the magnetic system itself is built to last.

But magnetic locks do have some downsides you should know about. They need constant electricity to stay locked, so they'll unlock if the power goes out unless you have backup power. They also work best when the door closes completely flat against the frame - any gap weakens the magnetic hold. If you're installing them outside, weather and moisture can cause problems with the electrical parts.

What Are Magnetic Locks?

An electromagnetic lock is a door security system that uses magnetism to keep doors shut. Instead of using keys or mechanical parts like traditional locks, it creates a strong magnetic connection between the door and the frame.

The lock has two main pieces that make it work. The electromagnet goes on the door frame and contains wire coils that create magnetism when electricity flows through them. The armature plate is a flat piece of metal that gets attached to the door. When the electromagnet is powered up, it pulls the armature plate towards it with tremendous force.

The way it operates is quite straightforward. Electricity goes to the electromagnet, which then becomes magnetic and attracts the metal armature plate. This magnetic pull holds the door closed with enough force to stop someone from pushing it open. When you cut the power or hit the release button, the magnetism disappears instantly and the door opens normally.

These locks need electricity flowing through them all the time to stay locked. This is different from regular locks that stay locked without power. The amount of electricity they use is small - about the same as a small light bulb - but they do need a steady power supply to keep working.

You'll see magnetic locks in commercial buildings and secure areas because they're strong and work well with electronic systems. Offices use them for employee doors where people scan cards to get in. Stores put them on back doors and storage rooms where they need security but also quick access. Even homes and apartments use them when people want the convenience of electronic entry systems instead of traditional keys.

‍

What Are the Different Magnetic Lock Types?

When you're looking at magnetic locks, you'll find they come in different styles that work better for different doors. Each type is designed to solve specific problems you might have with your door setup.

• Surface-mounted maglocks: These are the type most people see because they sit right on top of the door and frame where you can see them. The electromagnet goes on the door frame, and the metal plate goes on the door itself. You don't need to cut anything or make holes in your door to install them, which makes the job much easier. These work really well for glass doors because you obviously can't cut into glass to hide parts of the lock. If you have an office with glass entrance doors or a shop with aluminium doors, this is probably what you'll end up with. The frame on these doors is often too thin to fit other types anyway.
• Mortise maglocks: These are for when you want to hide the lock so it doesn't stick out. You have to cut a space into the door frame to fit the electromagnet inside, but then you can't see it from the front. The metal plate still goes on the door where you can see it, but the main part is hidden. This type works well when you don't have much room around your door frame, or when the door opening is tight and a surface-mounted lock would get in the way. You need a thick wooden door frame or a heavy metal frame to make room for the electromagnet to fit inside.
• Shear locks: These work differently because the magnetic force pulls sideways instead of straight toward the magnet. When you open the door, the metal parts slide past each other rather than pulling apart. This sliding motion is why they call it a "shear" lock. These are good for doors that don't sit perfectly flat when they close, or for gates and doors that move around a bit. If your door has some wiggle room when it's closed, a shear lock can still hold it securely.

‍

How Does a Magnetic Lock Work?

The whole system works because of how electricity creates magnetism. Inside the electromagnet, there are coils of copper wire wrapped around an iron core hundreds of times. When electricity flows through these wire coils, it turns the iron core into a powerful magnet that can attract metal objects.

This is the same basic principle that makes electric motors work in your car or the generator at a power station. The flowing electricity creates what we call an electromagnetic field around the iron core. This invisible field reaches out from the electromagnet and pulls on anything made of iron or steel that gets close enough. Since the armature plate on your door contains iron or steel, it gets pulled toward the electromagnet with incredible force.

When you turn on the power, electricity starts flowing through all those coils of wire inside the electromagnet. This creates the magnetic field that reaches out and grabs onto the metal plate on your door. The magnetic pull holds everything together with hundreds of pounds of force - much stronger than you could pull with your hands. If you increase the amount of electricity flowing through the coils, the magnetic field gets even stronger.

Here's what happens when the power goes out - the magnetic lock unlocks immediately because there's no electricity to keep the magnetic field going. Without power running through the wire coils, the electromagnet becomes just a regular piece of iron that doesn't attract anything. Anyone can then push the door open from either side. This is why people call magnetic locks "fail-safe" - they automatically unlock when something goes wrong with the power, so people can always get out during emergencies.

This is completely different from regular locks that use keys. Those mechanical locks stay locked even when the power goes out, but magnetic locks always unlock. This safety feature stops people from getting trapped inside buildings during power outages or fires. The downside is that your door becomes unlocked and unsecured until the power comes back on.

Control systems decide when the magnetic lock should engage and release during normal use. These systems include things like card readers where you swipe your badge, keypads where you enter a code, push buttons that anyone can press, and computer networks that can control the lock remotely. When someone swipes an authorised card or types in the right code, the control system cuts power to the electromagnet for a few seconds so the door can open. Motion sensors can also be part of this system to automatically unlock doors when people walk up to them from the inside.

You can have simple control systems or really complex ones depending on what you need. A basic setup might just have a push button on the wall that unlocks the door when someone presses it. Fancy systems connect to computers that keep track of who comes and goes, what time they used their access card, and whether their card is still allowed to work.

‍

How Much Do Magnetic Locks Cost?

The price of magnetic locks changes quite a bit depending on what you're looking for and how strong you need them to be. If you're just doing a home installation, you can get away with the basic residential locks that don't cost as much. These smaller ones have enough holding power for most houses and work fine for everyday use.

When you're looking at commercial places, the locks cost more because they're built tougher and need to last longer. The really strong ones that can handle heavy use and bad weather are going to be at the top of the price range.

The installation is a separate cost from buying the lock itself, and it really depends on how complicated your job is. If you already have the right wiring in place and it's a straightforward setup, the labour won't be too expensive. But if you need new electrical work, want to add card readers or other fancy access controls, or have tricky mounting situations, you're looking at a lot more work and higher labour costs.

Home installations usually cost less overall because they're simpler jobs. You're typically dealing with standard doors and basic wiring, so the whole project stays pretty manageable.

Commercial jobs cost more because they're usually more complicated. You might have multiple doors to do, complex access control systems to set up, and you need the heavy-duty locks that can handle constant use. Big commercial projects can sometimes get better pricing per door, but the total amount you're spending adds up fast.

The type of access control you want makes a big difference in what you'll end up paying. If you just want a simple push button that unlocks the door, that keeps things affordable. But if you want card readers, keypads, or those fancy fingerprint scanners, you're adding a lot to the total cost because of all the extra equipment and wiring.

‍

How to Choose the Best Magnetic Locks to Install?

The biggest thing you need to figure out first is how much holding force you actually need. This really comes down to how secure you want your door to be and what kind of problems you're trying to prevent. For most homes, you don't need the strongest locks available - something with moderate holding force will stop casual break-in attempts just fine. But if you're protecting a business or high-security area, you want the locks with maximum holding power.

Think about how someone might try to force your door open and how much pressure they could realistically apply. A door that just needs to keep out opportunistic intruders doesn't need nearly as much holding force as a door that's protecting expensive equipment or sensitive information. Keep in mind that the holding force only works properly when your door closes completely flush - any gap between the magnet and the metal plate makes the lock much weaker.

Your door material and where it's located really matter when you're choosing which type of lock to get. Glass doors pretty much force you to use surface-mounted locks because you obviously can't cut holes in glass to hide parts of the lock. Metal doors can work with the hidden mortise locks if the frame is thick enough to cut the space out. Wooden doors usually work with either type, but it depends on how much room you have around the door frame.

If your door is inside a building, you don't have to worry about weather, which makes things easier. But outdoor installations are trickier because the lock has to handle rain, hot and cold temperatures, and humidity without breaking down. You definitely want to look for locks that are rated for outdoor use if they're going to be exposed to weather. The electrical parts are especially sensitive to getting wet, so proper weatherproofing is really important.

The way you want people to access the door determines what other equipment you'll need and how everything connects together. RFID card readers are really popular in office buildings because employees can just carry cards in their wallets and you can easily control who gets access. Keypads work well when you have multiple people who need access but you don't want to hand out physical cards to everyone. Biometric scanners that read fingerprints are the most secure option, but they're also the most expensive.

Each of these access methods needs different wiring and connects to the magnetic lock in its own way. Some systems need their own separate power supplies, while others can share power with the lock. You want to make sure whatever access method you choose actually works with the magnetic lock you're thinking about buying.

You need to check the electrical compatibility before you buy anything. Most magnetic locks work on either 12-volt or 24-volt systems, and this has to match up with your power supply and control equipment. Some buildings already have the right low-voltage systems installed that work perfectly with magnetic locks. Others need completely new electrical work done.

The voltage affects how much electrical current the lock uses and what size wires you need to run. Higher voltage systems let you use thinner wires over longer distances, which can sometimes make the installation job easier. It's worth checking what electrical systems your building already has before you decide on a lock voltage.

Getting locks that meet official standards means you're buying quality products that have been properly tested for safety and security. ANSI Grade 1 is the top standard for commercial locks in North America, and locks with this rating have been put through tough tests for durability and security. EN 14846 is the European standard for electromagnetic locks, and products that meet this standard have passed strict tests for holding force and reliability.

These standards also cover important things like how the lock behaves when the power goes out, how much electricity it uses, and how long it should last with normal use. Sometimes insurance companies or building codes require locks that meet specific standards, so it's worth checking what's required for your particular situation before you make your final decision.

What Are the Security Features of Magnetic Locks?

The biggest thing that makes magnetic locks so secure is just how incredibly strong they are when they're holding a door closed. Most commercial magnetic locks can hold 600 to 1,200 pounds of force, which is way more than any person could overcome by pushing or pulling on the door. This massive holding power comes from the electromagnetic field that pulls the metal plate against the magnet with steady, reliable force.

When you think about it, 1,200 pounds of holding force means that even if someone tries to ram your door with their shoulder or use a crowbar to pry it open, the magnetic connection stays rock solid. This is completely different from regular locks that can be picked, bumped, or broken with the right tools and techniques. Magnetic locks don't have the usual lock parts that someone can mess with using traditional lock-picking methods.

The holding force stays exactly the same as long as there's power going to the lock. You don't get the gradual weakening that happens with regular deadbolts or door handles that wear out over time. The electromagnetic pull is either fully on or completely off - there's no halfway point where the lock becomes sort of secure but not really.

Magnetic locks are really hard to tamper with because of how they're designed and installed. The wiring that powers the whole system usually runs inside walls or through protective conduit where people who shouldn't be there can't easily get to it. This hidden wiring stops someone from just cutting the power wires to turn off the lock.

The brackets that hold everything in place and the electromagnet housing are installed so they're tough to remove or mess with. The electromagnet goes inside the door frame or on the secure side of the door where unauthorised people can't reach the bolts and screws that hold it in place. Even if someone could somehow get to these mounting points, the brackets are usually held on with special tamper-resistant screws that need special tools to remove.

The metal plate that goes on the door is usually the only part you can actually see, and it's designed to resist tampering too. Good quality plates are made from really hard steel and mounted with security screws that you can't remove with regular tools. Some designs actually build the metal plate right into the door itself, so you'd have to destroy the whole door to get it off.

When magnetic locks connect to electronic access control systems, you get even more security features. Since these locks work with computer systems, you can easily keep track of who comes and goes, what time people used their access cards, and whether someone tried to get in with a card that doesn't work. This electronic record gives you security information that regular mechanical locks just can't provide.

The way magnetic locks automatically unlock during power failures actually makes them more secure in many situations. They keep people from getting trapped during emergencies while still keeping your building secure during normal times. Fire safety rules require that people can always get out of buildings quickly when there's an emergency, and magnetic locks handle this automatically when the power goes out or fire alarms go off.

Many magnetic locks also have monitoring features that tell security systems when the door opens, when someone tries to force it, or when there are electrical problems. These monitoring abilities let security people know right away if something unusual is happening with the door, instead of finding out about problems hours or days later when it might be too late to do anything about it.

‍

How Secure Are Magnetic Locks?

When it comes to security, magnetic locks are really good at some things but have limitations in other areas. They provide high security for controlling who gets access to your building, but they offer moderate security when it comes to stopping someone who's trying to physically break in.

The access control side is where magnetic locks really excel. When you set them up properly with card readers, keypads, or fingerprint scanners, it becomes very hard for people who shouldn't be there to get through your door. You can easily decide who gets to enter, keep track of when people come and go, and immediately cut off access for anyone who shouldn't have it anymore. This kind of electronic control gives you way better security management than you could ever get with regular keys.

But here's the thing about magnetic locks - they need constant electricity to stay locked, and that makes them weak during power outages if you don't have backup power ready. When the lights go out, the lock automatically unlocks, which could leave your place completely unsecured. That's why smart installations include backup battery systems or uninterruptible power supplies to keep everything working even when the main power fails.

Magnetic locks really work best when they're part of a bigger security setup instead of trying to do everything by themselves. You want door sensors that can tell when someone opens the door without permission, and alarms that immediately alert security people when something's wrong. Motion detectors, security cameras, and other monitoring gear work together with the magnetic locks to give you multiple layers of protection and keep you aware of what's happening.

The automatic unlocking during emergencies is both good and bad for security. It's great because it makes sure people can always get out when there's a fire or other emergency, which fire safety rules require. But it also means the lock won't physically stop someone during power outages. If you have areas that absolutely need to stay secure even when the power's out, you might need to add mechanical backup locks alongside the magnetic ones.

When it comes to stopping someone who's trying to physically break in, the protection is moderate because even though the holding force is really strong, the whole lock shuts off when there's no power. Someone who knows how to cut the electricity to your lock or who tries to break in during a power outage won't face the same resistance they would with a regular mechanical lock that stays locked no matter what happens to the electricity.

‍

What Are the Advantages of Installing Magnetic Locks?

There are quite a few really good reasons why people choose magnetic locks for their security needs.

• Easy integration with access systems: These locks work really well with all the modern access control stuff like key cards, RFID systems, and fingerprint scanners. You can hook them up to computer security systems that handle multiple doors, keep track of who's coming and going, and give you detailed reports about who entered when. This makes magnetic locks perfect for offices, apartment buildings, and other places that need fancy access management without a lot of hassle.
• High durability and low mechanical wear: The great thing about these locks is they don't have a bunch of moving parts that can break or wear out. Regular mechanical locks have springs, pins, and other bits that slowly wear down every time someone uses them, but magnetic locks keep their full strength and work perfectly for years and years. The electromagnetic part doesn't get weaker from being used over and over, so your lock works just as well after thousands of uses as it did when it was brand new.
• Strong holding force up to 1,200 pounds or more: The electromagnetic holding power is way stronger than what any person could overcome just by pushing or pulling. This incredible holding strength gives you excellent protection against people trying to force their way in. Even if someone's using tools or trying to ram the door, they'll find it extremely hard to beat that magnetic attraction when everything's installed right and getting power.
• Fail-safe operation enables emergency safety compliance: When the power goes out, these locks automatically unlock so people can always get out of buildings during emergencies. This feature helps buildings follow fire safety rules and emergency exit requirements without messing up your everyday security. Emergency responders can also get into buildings easier during power outages since the locks automatically turn off.
• Quick locking and unlocking response for high-traffic flow: Magnetic locks turn on and off instantly the moment the electrical signal changes. There's no waiting around like you might get with motor-driven locks or complicated mechanical systems. This instant response makes them perfect for busy entrances where people need to get through quickly, like office buildings during rush hour or places that get lots of deliveries throughout the day.

All these benefits together make magnetic locks really suitable for modern security situations where you need good electronic access control, something reliable that lasts, and compliance with emergency safety rules all at the same time.

‍

What Are the Disadvantages of Installing Magnetic Locks?

While magnetic locks have plenty of good points, they definitely come with some downsides that you should think about before you decide they're the right choice for you.

• Requires continuous power supply to maintain lock: Regular mechanical locks just stay locked whether there's electricity or not, but magnetic locks need power running through them constantly to keep doing their job. This means your power bill goes up a bit, and any time there's trouble with your electrical system, it messes with your security. You're basically giving up the simple reliability of mechanical locks for something that depends on keeping the electricity flowing all the time.
• Can automatically disengage during power failure: The moment your power goes out, magnetic locks unlock immediately and stay that way until the electricity comes back on. This is actually good for fire safety since people can always escape during emergencies, but it also means your place is completely unsecured during blackouts. If you're somewhere that loses power a lot or has sketchy electricity, this could really hurt your security.
• Not resistant to forced entry without supplemental measures: Even though the holding force is incredibly strong when there's power, magnetic locks don't give you the physical barriers that regular locks do. Someone who cuts your power or tries to break in during an outage doesn't face any physical resistance at all. You usually end up having to add door reinforcement, security cameras, alarms, or backup mechanical locks to get the same kind of physical protection that a good deadbolt gives you right out of the box.
• More expensive than mechanical locks: Getting magnetic locks costs way more upfront than traditional mechanical locks. You're not just paying for the lock - you also need power supplies, control systems, and usually professional installation too. When you add everything up including the lock itself, electrical work, access control gear, and installation costs, you could end up paying several times what a really good mechanical lock would cost.
• Needs skilled installation with electrical connection: You can't just install these yourself like you might do with a regular deadbolt from the hardware store. Magnetic locks need proper electrical connections, often brand new wiring, and they have to work with control systems. This means you're hiring electricians or specialised security people, which adds to both the cost and the hassle. If the installation isn't done right, you could have safety problems or locks that just don't work properly.

‍

What Are the Common Issues with Magnetic Locks?

The biggest problems people run into with magnetic locks are power supply failures that make the locks unlock when they shouldn't, doors that don't line up properly which makes the holding force weaker, electrical connection troubles that make the whole system unreliable, and headaches trying to get the locks to work properly with access control systems like card readers and keypads.

‍

What Are the Tips for Maintaining Magnetic Locks?

Taking care of your magnetic locks isn't too complicated, but you do need to stay on top of a few important things to keep them working right. The most important thing is keeping the electromagnet and the metal plate clean - dust, dirt, and grime build up over time and can really weaken how well the magnet grabs onto the plate. Even just a thin layer of dust can make your lock much less secure, so you want to wipe both parts down regularly with a clean cloth. You should also keep an eye on all the wiring and make sure your power supply is delivering steady electricity, because loose connections or power that goes up and down can make your lock work unreliably or stop working completely. It's a good idea to test your access system every month by trying out your cards, keypads, or whatever entry method you use to make sure everything's still talking to each other properly and the lock turns on and off when it should. Don't put any oil or lubricant on the magnetic lock itself, but you do need to keep the moving parts of your door well-lubricated - things like hinges and door closers need to work smoothly so your door keeps lining up properly with the lock. You also want to check regularly that everything's still aligned correctly, because doors can start to sag or shift over time, and even tiny gaps between the magnet and the metal plate can make your lock much weaker and hurt your security.

‍

How Long Do Magnetic Locks Typically Last?

Magnetic locks typically last 10 to 15 years when you take care of them properly and do regular maintenance. They can last even longer than that if you're using them indoors and your electricity is stable, since being inside protects all the electrical parts from weather damage and having consistent power means the electromagnetic system doesn't get stressed out from voltage changes that can make things fail early.

‍

How Do Deadbolts Compare to Other Types of Locks?

When you're looking at deadbolts versus magnetic locks, there are some really big differences in how they work and what kind of protection they actually give you. Deadbolts are much better at stopping someone who's trying to force their way through your door because they use a solid chunk of metal that slides right into the door frame. Even if someone cuts your power or messes with your electrical system, that metal bolt is still sitting there doing its job and keeping your door locked tight. Magnetic locks just can't give you that same protection when the electricity goes out.

The best thing about regular deadbolts is they don't care whether you have electricity or not - they stay secure no matter what. Once you turn the key or twist the thumb turn, that bolt slides into place and it's staying there until you physically unlock it. You don't have to worry about power outages, electrical problems, or someone cutting wires to shut down your security. This rock-solid reliability is why deadbolts work so well for homes where you want protection that works regardless of what's going on with your power.

Electrified deadbolts give you something pretty interesting - they're like a compromise between regular deadbolts and magnetic locks. These locks have the physical toughness of a deadbolt but you can control them electronically too. Unlike basic magnetic locks that unlock automatically when the power dies, electrified deadbolts can be set up to stay locked even when there's no electricity. This means you get the convenience of electronic access control but you still have that physical security when the lights go out.

The downside with deadbolts is they're not nearly as convenient for busy areas or places where you need fancy access control features. You can't easily hook up regular deadbolts to card readers, computer systems, or time-based access like you can with magnetic locks. Electrified deadbolts can handle some of this stuff, but they're more complicated and cost more than basic magnetic locks.

‍

What Are the Alternatives to Magnetic Locks?

If magnetic locks aren't looking like they'll work for what you need, there are quite a few other locking options that might be a better fit.

• Electromechanical locks: These mix the physical toughness of regular locks with electronic control features. They use little motors or electrical devices to move deadbolts or latches when they get electronic signals from card readers or keypads. These work really well for office buildings and commercial places where you want card access but also need the lock to stay secure when the power goes out. They're more complicated than magnetic locks but give you better physical protection when there's no electricity.
• Electrified panic bars: These are those horizontal bars you push to get out that you see on lots of commercial doors, but with electronic locking built in. They automatically unlock from the inside when someone pushes the bar, which meets fire safety rules, but you can control them electronically from the outside. These are great for emergency exits, back doors of stores, and any door where people need to get out easily but you want to control who gets in.
• Traditional mechanical deadbolts: These are just your regular deadbolts that use keys and don't need any power at all. They give you excellent physical security and reliability since there's nothing electrical that can break. They're perfect for houses, small businesses that don't need access control systems, or as backup security for doors that already have electronic locks. The only real downside is you can't connect them to modern access control systems.
• Smart locks with Wi-Fi or Bluetooth access: These locks connect to your phone or home internet and let you control them from anywhere. You can unlock your door when you're not even home, give temporary access to visitors, and get alerts on your phone when someone comes in. They're getting really popular for homes and small offices where you want convenience and some access control without all the complexity of commercial systems.
• Biometric fingerprint locks: These scan your fingerprint to control access so you don't need cards or codes that can get lost or stolen. They work well for high-security areas, personal safes, or anywhere you want to make absolutely sure only certain people can get in. The technology has gotten much better and cheaper over the past few years, so they're actually practical now for both homes and businesses.

Each of these options has its own strong points and works best in different situations depending on what kind of security you need, how much you want to spend, and whether you care more about convenience or physical protection.
