What to Know About Wi-Fi Lock

A Wi-Fi lock is an electronic lock that uses IEEE 802.11 wireless protocol to operate over internet networks. Think of it as your regular door lock, but much smarter. This device is part of the growing world of smart home IoT security devices that work alongside your existing home setup. The main thing to understand is that your Wi-Fi lock needs continuous wireless internet connectivity to work properly and stay connected to your smartphone or smart home hub.

What makes these locks so appealing is how they give you security features that regular locks just can't match. You can control who gets into your property from anywhere, keep tabs on when people come and go, and even give temporary access to visitors when you're not home. It's no wonder more Australian homeowners and businesses are making the switch, they get the best of both worlds with convenience and stronger security rolled into one.

Let's talk about what actually makes up a Wi-Fi lock. The heart of it is the electronic deadbolt mechanism that does the actual locking and unlocking work. Many models also come with biometric sensors like fingerprint scanners if you want that extra layer of security. Behind the scenes, integrated firmware manages all the lock's operations without you having to think about it. The smartphone connectivity features are what let you control everything from your phone, which is pretty handy. These locks run on AA lithium batteries or rechargeable batteries that charge via USB-C, so you don't have to worry about them stopping work during power outages.

When you're shopping around, you'll come across several well-known brands. August makes various Wi-Fi smart lock models that have become quite popular with homeowners. Yale offers their Connect smart locks, which have built up a reputation for reliable performance. Then there's Schlage with their Encode Plus Wi-Fi deadbolts that many people have come to trust. Each of these Wi-Fi smart lock models brings different features and sits at different price points, so you can find something that fits both your needs and your budget.

What Is A Wi-Fi Smart Lock?

A Wi-Fi smart lock is basically a smart lock that uses your home's Wi-Fi network as its main way to talk to your phone, tablet, or smart home system. Now, you might be wondering how this differs from other smart locks you've heard about. While some smart locks use Bluetooth or Z-Wave technology to connect, Wi-Fi smart locks go straight to your home's wireless internet network. This direct connection is what makes all the difference, you can control your lock from anywhere you have internet access, not just when you're close to your door.

These locks are designed from the ground up to work with smart home security systems. They play nicely with the popular platforms you probably already know Google Home, Amazon Alexa, and Apple HomeKit. Here's how it works: when you want to lock or unlock your door, your lock receives encrypted commands through your Wi-Fi network. These commands then tell the electronic deadbolt to do its job safely and securely.

The real game-changer with Wi-Fi smart locks is how they give you remote access and control. Let me paint you a picture, you're sitting at work when that nagging thought hits you: "Did I remember to lock the front door?" With a Wi-Fi smart lock, you can check and lock your door right from your desk. Or maybe your teenage daughter gets home from school and realises she's forgotten her keys again. That's not a problem because you can unlock the door for her remotely. This kind of flexibility is why Wi-Fi smart locks have become so popular with busy homeowners, property managers, and business owners who need to stay in control of who can access their property.

But it gets even better. These locks send notifications straight to your phone whenever someone locks or unlocks the door. So you always know what's happening at your door, even when you're miles away. The locks also keep a digital record of every time someone comes or goes, and you can check this history anytime through the manufacturer's app. It's like having a security guard who never sleeps and always remembers everything.

‍

What are the Different Wi-Fi Smart Lock Types?

When you're shopping for a Wi-Fi smart lock, you'll find there are several different types available, and each one works a bit differently. The main differences come down to how they connect to your door, how you unlock them, and what kind of mechanism they use. Let me walk you through the options so you can figure out what might work best for your situation.

• Deadbolt-integrated Wi-Fi locks: These are the most straightforward option, they completely replace your existing deadbolt with a brand new smart unit. Everything you need is built right into one piece, including the Wi-Fi components and the locking mechanism. Because everything works together as one system, these tend to be the most reliable. You get consistent performance since there's no mixing and matching of different parts.
• Retrofit smart locks: Now, if you're happy with your current deadbolt and don't want the hassle of replacing it completely, retrofit locks are pretty clever. These attach to the inside of your door and work with whatever deadbolt you already have. The smart part turns your existing deadbolt from the inside, while your original key still works from the outside. It's like getting the best of both worlds, you keep what you have but add all the smart features.
• Lever-handle integrated types: Some doors use lever handles instead of the traditional round door knobs, especially in offices and newer homes. These smart locks are built specifically for lever-style doors. The Wi-Fi technology gets integrated right into the lever mechanism, so you still get that easy-to-use lever action plus all the smart connectivity you want.
• Keypad-enabled Wi-Fi locks: These are great if you want to ditch your keys entirely. You get a number pad right on the lock where you punch in your code to get in. But they're not just basic keypad locks, they connect to your Wi-Fi network too, so you can still control them from your phone and get all those smart notifications and features.
• Fingerprint-enabled Wi-Fi locks: If you want to feel like you're in a spy movie, these locks use your actual fingerprint to let you in. They scan your finger to make sure it's really you before they unlock. They still connect to your Wi-Fi for remote control, but you get that extra security layer where only authorised fingerprints can open the door.
• Hybrid Wi-Fi/Bluetooth dual locks: These are pretty smart because they don't put all their eggs in one basket. They can connect to your Wi-Fi network for when you want to control them from far away, but they also have Bluetooth for when you're right at the door. This means if your internet goes down or your Wi-Fi acts up, you can still use your phone to unlock the door through Bluetooth.

‍

How Does a Wi-Fi Lock Work?

You might be wondering how these Wi-Fi locks actually do their thing. It's pretty fascinating when you break it down, and understanding how they work helps you see why they've become so popular with homeowners.

Everything starts with your home's Wi-Fi network, the same network that connects your laptop, phone, and streaming devices to the internet. Your Wi-Fi runs on something called IEEE 802.11 standards, which is just a fancy way of saying it follows certain rules that let all your devices talk to each other properly.

When you first get your Wi-Fi lock, you need to introduce it to your home network. This usually means putting the lock into a special setup mode and using your phone's app to give it your Wi-Fi network name and password. Once that's done, your lock becomes just another device on your home network, sitting there alongside your computer and smart TV.

Inside the lock, there's a small computer chip and a Wi-Fi radio that stays in constant touch with your home router. Think of it like having a conversation, your lock and router are always exchanging little messages through encrypted data packets. When you tap "unlock" on your phone, that command travels from your phone to the internet, then to your home router, and finally to your lock.

Here's the really clever part: your lock doesn't just do whatever it's told. It has security checks built in to make sure each command is actually coming from you and not from some random person trying to break in. The lock looks at digital certificates and encryption keys, basically like checking someone's ID before letting them in. Only when everything checks out does the lock actually respond to the command.

The physical unlocking happens through a small motor inside the lock. When your lock gets a legitimate unlock command, this motor springs into action and moves the deadbolt or latch. The motor is smart enough to know exactly how far to move and can even tell if something's blocking its path.

Since these locks are always connected and listening for commands, they have to be pretty smart about managing their battery power. They spend most of their time in a low-power sleep mode, but they wake up instantly when you send a command or when someone approaches the door. It's like having a guard dog that sleeps lightly but is always ready to spring into action.

The communication goes both ways too. Your lock doesn't just receive commands, it also sends information back to your phone. That's how you get those instant notifications when someone locks or unlocks the door, and how your app can show you whether your door is currently locked or unlocked. It's this constant back-and-forth conversation that makes the whole smart lock experience work so smoothly.

‍

How to Choose the Best Wi-Fi Lock to Install?

Picking the right Wi-Fi lock for your home can feel overwhelming with so many options out there, but it doesn't have to be complicated. The key is knowing what to look for and understanding what really matters for your specific situation. Let me break down the main things you should think about before you make your decision.

The first thing you absolutely must check is compatibility with your existing door hardware. This might sound obvious, but you'd be surprised how many people get excited about a particular lock only to find out it won't fit their door. You need to grab a tape measure and check a few things: the backset (that's the distance from the edge of your door to the centre of the hole), how thick your door is, and which way it swings. Most Wi-Fi locks are made to fit standard doors, but older homes or doors with unusual setups might throw you a curveball. Some locks need specific hole sizes, and others just won't work with certain door frames. It's worth double-checking these measurements before you fall in love with a particular model.

Connectivity type is another big decision that affects how your lock performs day to day. Pure Wi-Fi locks give you the best range for controlling your lock from anywhere, but they can be hungrier for battery power and might struggle if your Wi-Fi signal gets weak near your front door. Hybrid locks that combine Wi-Fi with Bluetooth are pretty smart, you can use Bluetooth when you're right at the door and switch to Wi-Fi when you want to control it remotely. Some locks also work with smart home hubs like Z-Wave or Zigbee, which can be more reliable but mean you need extra equipment.

Your brand ecosystem matters more than you might expect, especially if you've already got other smart home gadgets. If you're already deep into Google Home, Amazon Alexa, or Apple HomeKit, you'll want a lock that works smoothly with what you already have. Some brands just play better with certain systems than others. Also think about the company behind the lock, do they have a good app? Do they update their software regularly? Are they known for helping customers when things go wrong? You don't want to end up with a lock from a company that disappears or stops supporting their products in a couple of years.

Don't forget to think about what features you actually need versus what just sounds cool. Do you want a keypad so family members can get in without using their phones? Would fingerprint scanning be useful for your household? How important is it to see who's coming and going? Some locks offer auto-locking, temporary codes for guests, or they work with security cameras. Make a list of what matters to you versus what's just nice to have, because more features usually mean spending more money and potentially having more things that can break.

‍

How Much Does Wi-Fi Lock Cost?

When it comes to pricing, Wi-Fi locks cover quite a range depending on what you're looking for and which brand catches your eye. You're looking at anywhere from about $200 for something basic up to $500 or more if you want all the premium features.

Basic Wi-Fi locks usually start around $200 to $300, and honestly, these might be all you need. They give you the main things most people want, you can lock and unlock from your phone, get basic notifications, and control everything through a simple app. If you just want the convenience of not fumbling for keys and being able to check if you locked up when you're already at work, these basic models do the job just fine.

Mid-range options sit in that $300 to $400 sweet spot and typically give you more bang for your buck. You'll often get keypad entry, better build quality that feels more solid, batteries that last longer, and apps that are more polished and easier to use. These locks usually integrate better with smart home systems too, and you get more options for setting up access codes and managing who can use the lock.

Premium Wi-Fi locks can run you $400 to $600 or even higher, and this is where you get into the really fancy stuff. We're talking fingerprint scanners, top-notch encryption, premium materials that look and feel expensive, and comprehensive smart home integration. Some of these high-end locks also offer two-factor authentication, which means you need both your phone and another form of verification to unlock the door.

The brand you choose makes a real difference in what you'll pay. Big names like August, Yale, and Schlage typically cost more than brands you might not have heard of, but you're often paying for peace of mind, better reliability, customer support that actually helps, and regular software updates. The level of security and encryption also bumps up the price. Locks with military-grade encryption and advanced security features cost more than basic models, but that extra security might be worth it depending on your situation.

Installation costs are something else to factor in if you're not comfortable doing it yourself. Many Wi-Fi locks are designed so you can install them yourself with basic tools, but some people prefer having a professional locksmith handle it. Professional installation usually runs between $100 to $200, depending on where you live and whether your door needs any modifications. If your door needs changes to fit the new lock, that can add to the bill.

Here's some good news, most Wi-Fi locks don't hit you with monthly fees for the basic features. The core functions like locking, unlocking, and basic notifications usually work without any ongoing costs. Some manufacturers do offer premium cloud services for extra features like extended access logs, fancy sharing options, or integration with professional monitoring services. These subscriptions typically cost around $3 to $10 per month if you decide you want them, but your lock will work perfectly fine without them.

When you're planning your budget, don't forget about the ongoing costs like batteries or charging cables, especially if you pick a model that uses special rechargeable batteries. Some locks also have optional add-ons like door sensors or security cameras that can increase your total investment but might be worth it if you want a complete smart security setup.

Who Can Install Wi-Fi Lock in Sydney?

When you're ready to get your Wi-Fi lock installed in Sydney, you've got a few different options depending on what your door needs and how tech-savvy you're feeling about the whole thing.

Licensed locksmiths are probably your safest bet, especially if you want someone who really knows what they're doing with door security. These are the professionals who've been through proper training and have the right credentials to work on security devices. In Australia, locksmiths have to be licensed through something called the Security Licensing & Enforcement Directorate (SLED) here in NSW. This means they've done the required coursework, passed background checks, and know their way around door hardware and security requirements. If your door needs any modifications or if you just want the peace of mind that comes with professional installation, these are your people.

Smart home technicians are another route you can take, particularly if you're planning to connect your Wi-Fi lock to other smart devices around your home. These technicians live and breathe smart home technology, so they're excellent at making sure everything talks to each other properly. They know how to get your lock working seamlessly with your existing smart home setup. Just keep in mind that if your door needs any physical changes, you'll still need to bring in a licensed locksmith for that part.

In Australia, anyone who works on security devices like locks needs to have the right qualifications. For locksmiths, that means completing a Certificate III in Locksmithing (MSF30218) and getting their security licence sorted. Smart home technicians should have relevant qualifications in electronics or telecommunications, though the exact requirements can vary depending on what they're doing.

What are the Benefits of Installing Wi-Fi Lock?

Getting a Wi-Fi lock installed brings some genuinely useful benefits that can make your daily life easier and give you better control over your home's security. These aren't just fancy features for the sake of being fancy. They actually solve real problems that homeowners deal with every day.

• Remote locking and unlocking: This is the feature that most people end up loving once they get used to it. You can lock or unlock your door from absolutely anywhere as long as you've got internet access. Picture this: you're sitting at your desk at work and suddenly that nagging thought hits you: "Did I lock the front door?" Instead of worrying about it all day, you just pull out your phone and check. If it's unlocked, you can lock it right there from your office chair. Or maybe you're running late and your teenager needs to get in but forgot their keys again. You can unlock the door for them and lock it back up once they're inside, all without leaving wherever you are.
• Real-time activity alerts: Your Wi-Fi lock becomes like having a friendly security guard who sends you text messages. Every time someone locks or unlocks your door, you get a notification on your phone. This means you always know what's happening at your front door, even when you're miles away. You'll know when your kids get home from school, when your partner heads off to work, or if someone's trying to get into your house when you're not expecting visitors. It's like staying connected to your home's daily rhythm no matter where you are.
• Keyless entry convenience: If you've ever stood outside your door in the rain, fumbling through your bag or pockets looking for your keys, you'll appreciate this one. With a Wi-Fi lock, your smartphone becomes your key. No more jingling keychains or panic when you can't find your keys. You can also set up number codes for family members, so everyone can get in without needing to carry physical keys around. This is brilliant for families with teenagers who have a talent for losing keys, or anyone who's just tired of carrying a pocket full of metal around.
• Integration with smart home ecosystems: Wi-Fi locks play really nicely with popular smart home systems like Google Home, Amazon Alexa, and Apple HomeKit. You can create routines where your lock works together with your other smart devices. For example, when you tell your smart speaker "goodnight," it can lock your doors, turn off all the lights, and maybe even set your security system. This kind of integration makes your whole home feel smarter and more convenient to manage.
• Enhanced access control with 2FA and biometric access: Many Wi-Fi locks offer some pretty sophisticated security features that go way beyond traditional locks. Two-factor authentication means you need both your phone and another form of verification to unlock the door, like entering a code or using your fingerprint. Some models have fingerprint scanners built right in, so only people whose fingerprints are registered can get in. These extra security layers give you much more control over who can access your home compared to regular locks where anyone with a copy of your key can walk right in.
• Auto-locking and scheduled access for guests: One of the handiest features is auto-locking, where your lock automatically secures itself after a certain amount of time. This means you never have to lie awake at night wondering if you remembered to lock the door. You can also create temporary access codes for guests, cleaners, or repair people that only work during specific times or on certain days. Once the time you've set expires, those codes just stop working automatically. This is perfect for things like holiday rentals, letting contractors in while you're at work, or giving friends access to house-sit without worrying about getting your keys back later.

‍

How Secure are Wi-Fi Locks?

Wi-Fi locks are actually quite secure when you get them from reputable manufacturers and set them up properly, though like any connected device, there are some things you should know about their security. Most quality Wi-Fi locks use pretty robust security protocols to keep your data and communications safe. They typically use something called Transport Layer Security (TLS) encryption for all the conversations between your phone, the cloud servers, and the lock itself. This is the same type of encryption that your bank uses when you're doing online banking, so your lock commands get scrambled in a way that makes them extremely difficult for anyone to intercept and figure out. The apps that control these locks also use encrypted login systems, and they often require strong passwords. Many even offer two-factor authentication if you want that extra layer of protection.

When it comes to physical security, good Wi-Fi locks are built with anti-tamper features that make them tough to break or mess with. Many models actually have stronger deadbolts than traditional locks, and they often include sensors that can tell if someone's trying to physically tamper with the lock mechanism. If someone tries to force the lock or remove it from your door, many models will set off alarms and send alerts straight to your phone. Auto-lockout features are another smart security measure where the lock will temporarily shut itself down if someone enters too many wrong codes or tries to access it inappropriately several times in a row.

The security of your Wi-Fi lock also depends a lot on keeping your home network secure and making sure the lock's software stays updated. Most manufacturers regularly put out security updates, and it's really important to install these when they come out. While no security system is ever 100% foolproof, a well-made Wi-Fi lock from a trusted brand that's properly installed and maintained typically offers better security than traditional mechanical locks. You get the physical protection plus digital security layers and real-time monitoring all working together.

‍

What are the Disadvantages of Installing Wi-Fi Lock?

While Wi-Fi locks offer plenty of benefits, they're definitely not perfect for every situation, and there are some real drawbacks you should think about before making the switch.

• Dependency on stable Wi-Fi connection: Your Wi-Fi lock needs a reliable internet connection to work properly, and this can become a real headache if your Wi-Fi goes down or starts acting up. If your router decides to quit or your internet service provider has an outage, you might lose the ability to control your lock remotely or get those handy notifications. Some locks have backup options like Bluetooth, but others might leave you standing outside your own door if the Wi-Fi fails at exactly the wrong moment. This dependency on technology can be really frustrating for people who appreciate the simple reliability of traditional mechanical locks that just work, no matter what.
• Battery power limitations: Unlike traditional locks that work purely through mechanical action, Wi-Fi locks need power to operate, and most of them run on batteries that need regular replacement or recharging. Depending on how often you use the lock and which features you've got turned on, those batteries might last anywhere from a few months to over a year. The real inconvenience comes when batteries die unexpectedly, potentially leaving you unable to unlock your door electronically. While most locks give you low-battery warnings and still have backup key access, it's an ongoing maintenance job that mechanical locks just don't require.
• Potential cybersecurity vulnerabilities: Like any device that connects to the internet, Wi-Fi locks can potentially be targeted by cybercriminals. While quality locks use strong encryption, there's always some risk that hackers could find ways to exploit weaknesses in the software or try to intercept communications. Cheaper or poorly designed locks might have weaker security measures, making them easier targets for digital attacks. There's also the worry that if a manufacturer's servers get compromised, it could potentially affect all their connected locks out there.
• Higher upfront costs compared to mechanical locks: Wi-Fi locks cost quite a bit more than traditional deadbolts. You're often looking at several hundred dollars compared to $50 or less for a good mechanical lock. When you add in potential installation costs and ongoing expenses like batteries or subscription services, the total cost of ownership can really add up. For homeowners watching their budget or those who don't see much value in smart features, this cost difference can be tough to swallow.
• Cloud service reliance for some functionalities: Many Wi-Fi locks depend on the manufacturer's cloud servers for certain features like remote access, access logs, and app functionality. This means if the company's servers go down, have problems, or if the company goes out of business entirely, you could lose access to these features. Some manufacturers also charge ongoing subscription fees for premium cloud features, which adds to your long-term costs. There's also the privacy angle that your lock usage data is being stored on someone else's servers, which makes some people uncomfortable about who might have access to information about their daily routines.

‍

How Long Does Wi-Fi Lock Typically Last?

Wi-Fi locks typically last around 3 to 5 years depending on how much you use them and what type of battery system they have. This lifespan is pretty reasonable when you think about it because these devices are basically small computers that are working around the clock to stay connected to your network and respond to your commands. The actual longevity can vary quite a bit based on several things, but most people find they get good value from their Wi-Fi locks during this time before they start thinking about upgrading to newer models with better features.

Several things really affect how long your Wi-Fi lock will keep working well. Firmware updates play a huge role in longevity because manufacturers regularly release updates that fix bugs, improve security, and sometimes even add new features. Locks that get regular updates tend to last longer and work better over time. Hardware quality is another big factor that separates the good locks from the not-so-great ones. Well-built locks with quality components can handle the daily wear and tear of opening and closing, while cheaper models might start having mechanical issues after a year or two. Environmental exposure also matters more than you might think. Locks that face harsh weather conditions, extreme temperatures, or high humidity will typically wear out faster than those in protected spots.

When you're shopping for a Wi-Fi lock, it's worth looking into brands that offer replacement parts or extended warranties. Companies like Yale, August, and Schlage often provide replacement parts for their locks and offer extended warranty options that can give you peace of mind about your investment. Some manufacturers even have upgrade programs where they'll give you a discount on a newer model when your current lock reaches the end of its useful life. These kinds of support options can really extend the practical lifespan of your lock investment and make sure you're not left hanging when something goes wrong.

‍

How Do Wi-Fi Locks Compare to Other Types of Locks?

Understanding how Wi-Fi locks stack up against other lock types helps you figure out what's going to work best for your specific situation and needs.

• Compare with Bluetooth locks: The biggest difference between Wi-Fi and Bluetooth locks comes down to range and connectivity. Wi-Fi allows remote access from anywhere you have an internet connection, so you can lock or unlock your door from across town if you need to. Bluetooth locks, on the other hand, are local only and typically work within about 30 feet of your door. This means you need to be physically close to use a Bluetooth lock, but you get the convenience of not needing an internet connection to make it work. Wi-Fi offers broader smart home integration because it can connect directly to your home network and work with various smart home platforms, security systems, and automation routines. Bluetooth locks have more limited integration options since they rely on your phone as the go-between. However, Bluetooth generally uses less power than Wi-Fi locks, so the batteries in Bluetooth locks often last longer between replacements. Bluetooth locks also tend to be more reliable in areas with spotty Wi-Fi coverage.
• Contrast with traditional locks: The differences here are pretty dramatic in terms of what you can actually do. Wi-Fi locks offer keyless and remote entry plus logging features that completely change how you interact with your door. You can unlock remotely for guests, create temporary access codes, get notifications when people come and go, and see a complete history of who accessed your door and when. You can also connect them with other smart home devices and create automated routines. Traditional locks have no connectivity and require physical keys, which means you need to be physically present to unlock the door and you have no way of knowing who's accessed your home when you're not there. Traditional locks are completely mechanical, so they don't need batteries, software updates, or internet connections to work. They're also typically much less expensive upfront and have proven reliability over decades of use. However, they offer no remote access, no access logging, no integration with security systems, and you're always at risk of being locked out if you lose your keys or forget them inside.

The choice between these different lock types really comes down to what you value most. If you want maximum convenience, remote access, and smart home integration, Wi-Fi locks are hard to beat. If you want something simple and reliable that just works without any fuss, traditional locks might be more your style. Bluetooth locks sit somewhere in the middle, offering some smart features without the complexity and potential connectivity issues of Wi-Fi locks.

‍

What are the Alternatives to Wi-Fi Locks?

If you're thinking about upgrading your door security but Wi-Fi locks don't feel like the right fit for your situation, there are plenty of other options that might work better for what you need.

• Bluetooth smart locks: These give you a lot of the smart features you'd get with Wi-Fi locks, but they work through Bluetooth instead of your internet connection. You can still control them with your phone and get that keyless entry convenience, but you need to be within about 30 feet of the door for them to work. They're great if you want smart lock convenience without worrying about internet connectivity issues, and they typically sip battery power compared to Wi-Fi locks. The catch is you can't control them remotely when you're away from home, so no unlocking the door for guests from across town.
• Biometric locks (fingerprint-based): These locks use your actual fingerprint to let you in, which feels pretty futuristic and offers excellent security since fingerprints are unique to each person. You don't need to remember codes or carry keys around, and they work even when the power goes out if they have backup battery power. They're perfect for people who want high security and convenience without any connectivity headaches. The main downsides are that they can sometimes struggle to read dirty or wet fingers, and they're typically more expensive than other non-connected options.
• Keypad electronic locks (non-Wi-Fi): These are basically digital locks that let you punch in a number code to unlock the door, but they don't connect to the internet or your phone at all. They're much simpler than smart locks but still give you that keyless entry convenience. You can usually program multiple codes for different family members, and many models let you create temporary codes for guests or service people. They run on batteries but typically last much longer than connected locks since they're not constantly chatting with networks.
• RFID/NFC access locks: These locks work with special cards, key fobs, or even NFC-enabled smartphones that you wave near the lock to unlock it. You've probably seen these in offices and hotels, but residential versions are available too. They offer convenient keyless entry and you can easily add or remove access for different people by programming new cards or disabling old ones. They're reliable since they don't depend on internet connectivity, but you do need to remember to carry the access card or fob with you.
• Mechanical key locks (traditional): Good old-fashioned locks that work with physical keys are still a solid choice for many people. They're incredibly reliable since there's no electronics to fail, they don't need batteries or software updates, and they're much less expensive than any smart lock option. They work in any weather condition and during power outages without missing a beat. The trade-offs are that you need to physically carry keys, you can't control them remotely, and there's no way to track who's coming and going.
• Z-Wave or Zigbee-based door locks for hub-based systems: These locks connect to smart home hubs rather than directly to your Wi-Fi network. If you already have a smart home hub like SmartThings, Hubitat, or a security system panel, these locks can integrate beautifully with your existing setup. They often have better range and reliability than Wi-Fi locks and can work even if your internet goes down, as long as your hub keeps running. The downside is that you need a compatible hub to make them work, which adds to the cost and complexity if you don't already have one set up.

Each of these alternatives has its own sweet spots and limitations, so the best choice really depends on what features matter most to you, your budget, and how much complexity you're comfortable with in your home security setup. Some people want all the bells and whistles, while others just want something simple that works every time.
