- Apple Home and Home Key SupportThe U100 is a smart door lock that is fully integrated into Apple Home. It can be unlocked with the Apple home keys by simply tapping an iPhone or Apple Watch, even when the iPhone or Apple Watch is out of power. Moreover, you can manage and share door access for your guests in Apple Home. (NOTE: To share Apple Home Keys, you need an Apple Home Hub)
- Fingerprint and More Ways to UnlockThe Smart Lock U100 offers multiple ways to unlock, including a high-precision fingerprint reader for up to 50 fingerprints, remotely configurable passwords via the Aqara Home app (An Aqara Zigbee 3.0 hub is required), one-time local passwords for visitors, and a mechanical key for emergency use. * The NFC card is not included and is sold separately.(Tips: After adding the door lock to the Aqara Home app, only the administrator's fingerprint or password can reset the door lock.)
- Automations with Aqara and Third-Party DevicesWith an Aqara Zigbee 3.0 hub, the Smart Door Lock U100 is compatible with third-party ecosystems like Alexa, IFTTT as well as the Aqara Home app, allowing it to be easily integrated into a wide range of smart home setups and used in smart home automations. For example, when someone presses the Aqara Video Doorbell G4, you will be able to view who is at your door and easily unlock the Door Lock U100. (Zigbee2MQTT and comparable third-party USB dongles are not officially supported by Aqara. Full product functionality may be limited or unavailable.)
- Auto Lock & Do Not Disturb ModeThanks to the built-in gyroscope inside the lock, the auto-lock feature locks the door for you after you close it. Alternatively, you can disable this feature and leave the door always open. Also, the Do Not Disturb mode can mute the door lock sounds within a certain period of time, to avoid affecting your familys sleep when you get back home late.
- A Durable and Secure Biometric door Lock with Long Battery LifeThe U100 is powered by four 1.5V AA alkaline batteries (Note: Do not use non-alkaline batteries) and offers a long battery life of up to 8 months. Also, a USB-C port for emergency charging is available. The lock body made of zinc alloy has an IP65 rating and complies with the same safety standard as BHMA Level 3.

I wanted a Smart Lock that would be easy to use, support Apple Home key, include fingerprint and a physical key option. The Aqara U100 has all of these features that I am looking for. I am replacing an existing deadbolt and was expecting a simple remove the old and then install the new, hoping the existing holes would work. I did end up having to get my drill out to enlarge the hole for the bolt, which took some effort and added 30 minutes to the installation. Luckily that was the only modification I had to make on my door. One thing that gave me a little trouble with the lock installation was making sure everything was level, I was off slightly in my first try and the fit was a bit off, with the bolt not functioning smoothly. It was easy to correct with the help of a level and hardware was installed. One thing to note is that I had some trouble pulling off the battery cover. Installation videos showed it easily pulling off but I had to use some plastic tools to pry it open. The Aqara app was easy to follow and adding the lock was straight forward. I did separately add an Aqara hub, as I will likely in the future, look to add the lock to Google Home. I first added the lock to the hub and then I added the hub to Apple Home. In Apple Home, both the hub and the lock appeared on my dashboard. I could control the lock from the Home app, but the Home Key feature did not work. I then added the lock directly to Apple Home, which enabled Home Key, but then it showed the lock twice on the Apple Home dashboard, which was confusing. I then deleted the first instance of the lock that was added by the hub so that I only had one instance. Tested and everything along with Home key worked. The Aqara U100 works really well. I can unlock by tapping my Apple Watch or iPhone. My wife and kids have Android phones, so they are accessing with fingerprint. I picked up an NFC card to try with the lock and it also works great, though defeats the purpose of being keyless but can be useful in certain situations such as visiting guests where a passcode is not optimal (elderly family members in my case). I am planning to set up Google Home later on, so that the lock can be opened via the Google Home app on Android. Too early to comment on battery life, but from reviews I've seen, I expect them last up to a year. The lock comes with batteries, but I did also get a 4 pack of lithium AA's to use with the lock, thinking that may provide a longer life between battery changes, but only time will tell. I really like this lock given the relative ease of installation and all of the options for unlocking. I would say that if you have an iPhone, this is worth a consideration. If you're an Android user, maybe not optimal, but still very usable. I picked up this lock during the recent Spring sale and feel this is was a very good purchase.

I started using Aqara products when I lived in China, and I have been a fan of the brand ever since. This smart lock was easy to install, and the battery life has been excellent. Both the fingerprint reader and keypad respond very quickly, so unlocking the door feels smooth and convenient. The Aqara app is also simple and clearly organized. Features such as automatic locking, user management, and creating temporary one-time passwords are all easy to set up and use. This is especially convenient when family members, friends, or service providers need temporary access. Overall, it is a reliable, responsive, and well-designed smart lock.

I was at a point where my wife would get mad at me if I was home after her work shift and I didn't unlock the door in time since her keys were always either lost, or deep in her large work bag. I decided to look into something where she didn't have to worry about her keys anymore and it was simple and reliable for her to use. This solved all our issues. This works with HomeKit almost perfectly except for one thing. I like the fact that the fingerprint reader is accurate and fast. It never feels like we're waiting too long for it to unlock. It takes maybe about a second to confirm your fingerprint, and then it makes a chime, and then you can hear the door unlock. I haven't had an issue with the fingerprint reader. I know some people have complained, but I just make sure my fingers are dry and it works 99% of the time. I think the biggest flaw when using the fingerprint reader is the angle that you programmed it at. I would say, program your reader with the door closed, and as close to a real-world scenario so the angle is as accurate as possible. I like that it also has a combination code (6-digits) that you can also program in, just in case your finger is dirty or wet. This is a good back up. I like that it has a physical key as well. I'm still someone that likes to carry my keys everywhere, and it just helps with ease of mind that I know if anything electrical fails (like the battery dying), I still have my physical key to use to enter. I haven't had any issues with the battery after 6 months, and the app still states that my battery percentage is high. I'm sure they last longer than the stated (8 months). I also like that it integrates with HomeKit. We both have iPhones and being able to use NFC by just tapping our phone on the door is amazing. I usually have my phone in my hands, and this is another cool feature to use, granted I don't use it as much as the fingerprint reader. Also, I cannot get the HomeKit key to work on my wife's phone, so I can't really recommend this as a good working feature. I wanted to be able to just share the key through HomeKit whenever I need to let someone in my home when I'm not there, but the way I've been doing that is just unlocking it through the HomeKit app when I know someone is waiting by the door. This takes about 30 seconds for it to unlock, but it's a nice feature to have when someone needs to get inside your home for an emergency. Overall, I would highly recommend these to anyone looking to get smart home locks. I've already received a couple of compliments and when people come over, they ask about them all the time. Don't spend too much time looking anywhere else, these locks make it easy to enter your home and make sure it is secured at the same time.

I purchased two of these, one for my front door and another for my garage door. The first one I installed was extremely easy and functioned without any issues. The second one on the other hand was an absolute nightmare and doesn’t work. First off with the pros: I was in the market for a smart lock that supports Apple HomeKey, and Aqara beats out the competition with having the most functionality AND being the most affordable. At the time of this writing, there are no other locks on the market that supports HomeKey, physical keys, NFC cards, and a keypad. On my first Aqara lock, everything works amazingly good and is very responsive. My second Aqara lock is another story I’ll discuss in the cons. Now with the cons: I wish it came in a silver/nickel option as most hardware would match it. The gray is a nice color, but it is hard to match as most door handles are usually silver or black. Moving on to my bad experience… The second Aqara lock I installed was a headache. One of the screws that came with the striker plate was completely defective. None of my different sized screwdrivers would seat properly inside the screw because the hole was so shallow. I initially had some traction screwing it in, but halfway through it required more torque which made it impossible to screw all the way in. I was left with a screw halfway in that I couldn’t even remove. I needed to go to the hardware store to buy a tool to get it out. This wouldn’t be a big deal, but I couldn’t leave my house as my front door won’t close and I was alone at the time! Absolute nightmare. Moral of the story, check your screws, before it screws you. Even after getting it successfully installed, that wasn’t the worst of my problems. The lock itself was constantly malfunctioning. It would go into this endless locking loop making the lock unusable (as shown in my video). After endless troubleshooting and reinstalling, I’m deeming this as a defective item. I want to give Aqara the benefit of the doubt, but it does leave me with the impression that there is some hit or miss build quality issues. If you do receive a working unit, it is an amazing product, which is why I’ll be requesting a replacement rather than returning it altogether. My only fear is how well this lock will hold up considering my experience so far. Only time will tell… Update 1: I got a replacement, and I am no longer experiencing issues as I did with my first unit. Initially I thought it may be an issue with my door set up, but that was definitely not the case. However, I am dropping my rating from 3 stars to 2 stars. I am now getting annoying malfunctions with the other lock that was considered fine in my initial review. The lock is beeping at random hours of the day and it’s driving me insane. It’s the same beep that happens as if I’m touching and waking the lock, but I’m obviously not. I also had one occurrence where the keypad glitched out and I was unable to lock my door from the outside. I was forced to use my other door to leave my house. The issue hasn’t happened again, but this experience does not sit well with me. I am getting the impression you really do get what you pay for. You may be better off spending more money for a more reliable lock. Update 2: Further dropping my rating from 2 to 1 stars. After only 3 weeks of use, I already got a low battery alert. This product is absolute trash and all of it is going back. Don’t bother with this cheap and poorly built lock.

Good quality. Residential grade but on the sturdy side. Doesn't feel cheap or plasticky, most of the body of the device seems to be made from die cast alloy of some sort. Fingerprint scanner works well and it's worth the price of admission on its own, and the code locking is handy for allowing other people access if needed. Backup lock cylinder looks more like something you'd find in a commercial lock set, so while I have no idea how good it is in terms of stuff like pick resistance it's at least physically solid. I have several Aqara zigbee sensors around the house and they work fine with Home Assistant over a USB zigbee dongle, but this device does not follow that pattern. It does actually require the Aqara hub, Home Assistant doesn't detect it at all over generic zigbee. A bit disappointing but can't say they don't warn you. However, it works great as a standalone device unattached to any home automation system, you can manage pretty much all the stuff it can do over bluetooth from the Aqara phone app. This is probably how I'll end up using it since I can set it up to auto-lock and already have a door sensor, so there's not much reason for HA to need to talk to it. Apparently with the current HA integrations using the Aqara hub you don't get any interesting user log data from the lock anyway, just door state and lock state. 4 stars, docking one because the only reason it's incompatible with open home automation systems is because the manufacturer wrote the software that way.

The first fingerprint lock I bought was the Ultraloq U-Bolt Pro and I loved it. The front door of the house I lived in at the time didn't get direct sun. The lock worked great, no lost keys, no one ever locked out. It really was super-convenient for us. At the new house, the door it was installed on gets a couple of hours of afternoon sun. It was probably somewhere around 1-1/2 years on the old house and less than 6 months on the new house when the surface of fingerprint reader started to flake off. The lock still worked by entering codes so we continued to use it for a while. Eventually, I bit the bullet and ordered a new Ultraloq but could not get it to work. I went through three new locks, who knows how many emails with customer support, and at least two support calls before I gave up and ordered this one instead. Here's how I think they compare. As for how they look, I think I prefer the Ultraloq but this is personal preference. To be clear, I don't dislike how the Aquara looks and now that its been installed a while, I never think about it. Fingerprint reader speed, as far as I can tell, is about the same for both, and both are fast. Faster than you could open a lock with a key. Fingerprint reading accuracy is a tough call but about the same. If I rate the Ultraloq at 100, I would rate the Aqara a 99. Functionality out of the box goes to the Ultraloq but only because I bought the Pro model. It connects to your Wi-Fi and you can control it from anywhere through its app. With the Aqara app, you can only control the lock when you are connected to it by Bluetooth. If you want away from home control, you'll need to buy a bridge, which I did. The bridge, apparently, has more functionality than just controlling the lock but the lock is the only Aqara product I have so I don't get anything extra out of it. Now, its rare that I need to control the lock away from home but when you need to... Both take 4xAA batteries and while I didn't write down how long they lasted (or used the same brand in both all the time) I think the Aqara last a little longer. Both last long enough that I never thought, jeez I'm changing the batteries again. Both locks give you plenty of notice that the batteries are getting low. Durability remains to be seen. The Aqara has been installed since Jan-2025, about 14 months as of this review. I discussed the problems I had with the Ultraloq above. In the end, I installed the Aqara and it worked like its supposed to. The first Ultraloq I bought was that way, its replacement was not and I gave it enough chances. I'm not looking for more problems in my life. Where I am, if the Aqara locks fails now, I'll complain that it didn't last longer (that would also be true five years from now) but I'll probably buy another one. I'm happy enough with it that I don't have a reason to try something else.

I got the Aqara Smart Lock because it works with Apple HomeKit, and I love the idea of just holding my phone or Apple Watch to unlock my door. It's super cool and convenient since I always have my phone and Apple Watch with me. Setting it up took a bit longer than I thought it would, but it wasn’t hard—just a little time-consuming. Once I got it up and running, it worked great with Bluetooth. The Bluetooth connection can take a few seconds to connect when I’m close to the lock, so it’s not instant. But once it connects, I can see logs of who opened or closed the door and control the lock. You really need the Aqara hub if you want to check logs or control the lock away from home. I ended up getting the Aqara Smart Hub E1, which is the cheapest one I could find. It took a bit of work to connect it to my Wi-Fi since it only works on 2.4GHz. I had to temporarily disable the 5GHz band on my Eero router, but thankfully, the Eero app made that easy. It disabled the antenna for 30 minutes, which was more than enough time to finish the setup. Make sure you set it up in the Aqara app first before syncing it with HomeKit. I accidentally tried to set it up in HomeKit first, and that caused the Aqara app to not recognize it, so don’t make the same mistake I did! Once the hub was connected, the lock connected super quickly, much faster than with just Bluetooth. You do have the option of controlling the lock with just an Apple HomeKit hub like an Apple TV or iPad without using the Aqara hub at all, but having the Aqara hub is way better. It gives you faster connections and access to all the management tools while away from home, unlike HomeKit, which only lets you lock and unlock it remotely. So if you just care about unlocking and locking while away from home and already have an Apple TV as a hub, then you technically don’t need the Aqara hub as well. Overall, I really recommend the Aqara Smart Lock. It’s the fastest operating lock I’ve ever used, the fingerprint sensor is the most accurate I’ve seen, and it’s been extremely reliable. It has so many ways of opening it that my family finds it very convenient. I love this lock, and I hope it continues to work well for many years.

Updated Review: Reducing my rating based on my 12/2025 purchase of two additional U100 locks. These most recent locks are deeply flawed! Functionality remains the same but the interior deadbolt handle, once installed, rubs against the body of the lock enough cause lock and unlock failures. There is no rubbing or contact with the frame of the door. The lock simply doesn't work consistently out of the box. Additionally, the included recessed attachment screws used to attach the interior part of the lock are VERY cheap now. The screw heads strip requiring you to drill them out if you need to get the lock off. It's a real shame! I was a true fan of all my Aqara locks. I currently have 4 of them on the entry doors to both our buildings (U100 and U300), and have another 6 U300 locks awaiting installation. This new experience is likely enough to make me switch brands. 😭 Original Review: We've been using our Level Lock Plus for about a year now and it's been a surprising disappointment. We incorrectly assumed that the build quality, marketing, US support, etc. meant it would do what we needed it to do. It didn't. So when we got a sale notice from Amazon on the Agara lock we figured we should give it a try. The documentation (which is available online when you scan the QR code in the box) could be better but the installation is just about what you'd expect. If you've installed smart locks before you'll be fine. The build quality of the lock is good, though if you've already had a "higher-end" lock like Levels it will feel cheaper. I don't believe it's cheaper in a way that would shorten the life of the lock or hinder its use in any way. It's a good quality product. The app, like the documentation, could be better. It's not as intuitive as most others and the keyboard (in iOS anyway) has a habit of covering the screen so you can't see what you're typing. It's a minor annoyance at best when you compare the functionality... This lock easily beats any of the locks I've had to date. It provides access via HomeKey and most NFC devices, a code with the integrated keypad, accurate fingerprint access, and a conventional key which is included (x2). Each user can store up to 10 prints which seem like overkill but I'll take it. Each individual print is saved using a collection of 6 scans (just like Apple's TouchID) and while I rarely use it, it's never failed to open the door on the first try. But if HomeKit and HomeKey are your primary reason for purchasing this lock just stop reading and buy it. With the Level Lock you have to wake and unlock your device before it'll unlock the door. I use both an iPhone and an Apple Watch. The Apple Watch refuses to open the level lock 90% of the time. Our cameras send us a notification when we get to the door so we need to clear that notification and return to the home screen for the lock to have any hope of opening. Most of the time it still doesn't. But the Aqara lock just works. Notification? It doesn't care. In Facebook? No problem. The HomeKey implementation is bulletproof. No fiddling or having to mess with stuff. If you hold either device to the lock it opens. We tested the Aqara U100 because our Level Lock was very unstable and uncooperative. The reason we switched was because the Level lock started unlocking on its own. We lock up and leave and the lock opens by itself 15 seconds later. Thus far the U100 has shown NO signs of being prone to similar faults. Conclusion: The Aqara U100 is a great lock. Its battery lasts longer and it performs far better than the presumed market leader by every metric. Can't see a reason to buy anything else. Congratulations Aqara! You put out a fantastic product. Thank you for it.
