Features

  • 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.
  • 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 Google Home, 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 U100.
  • 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 Life The U100 is powered by 4 AA 1.5V batteries (included) and has 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.

Is this a Wi-Fi-enabled smart lock? No, the U100 uses Zigbee, which offers higher security, faster response, and better stability than Wi-Fi. Note: Remote control requires a hub, such as an Apple Home Hub or an Aqara Zigbee 3.0 hub (e.g., G2H Pro, G3, G410, G5 Pro, M2, M3, M1S). If I don’t have a hub, can I still use the U100 smart lock? Yes, you can connect your phone to the lock via Bluetooth to set passwords, fingerprints, and modes. However, you won’t be able to use remote unlocking, connect it to Alexa or Google Home, or share Apple Home Keys without a hub. Can I connect the U100 to Google, Alexa, Matter, or Home Assistant? Yes, it works with Google, Alexa, and Matter, but you’ll need both an Aqara Zigbee 3.0 hub and the hub for the platform you want to use. It’s not compatible with Home Assistant. What type of batteries does the U100 use? Are there any requirements? Please use 1.5V alkaline batteries only. Using other types of batteries may cause the lock to malfunction or result in unstable performance.

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. ... show more

    • Love the options to enter our home
Color: Gray
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. ... show more

    • Very Fast and Reliable
Color: Gray
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. ... show more

    • Better than my old Schlage
Color: Gray
Why did you pick this product vs others?: Pros: Super easy to install. Nice features over other smart locks. Nice sturdy build. Apple Homekey works great (also see below). Fingerprint sensor works great. Cons: Knob on back feels a little flimsy compared to other locks I’ve tested. Homekey only works with one phone unless you buy a separate Apple hub device. Overall, this is a great lock and nicer than my 5-year old Schlage with much improved features. I was slightly let down for the lack of having the ability to have my family use Homekey without purchasing a separate hub. Although this is no fault of Aqara’s, it doesn’t seem to be explicitly mentioned in their advertising or documentation that you need to buy a hub to use Homekey with more than one device. ... show more

    • Impressive Features, Questionable Quality
Color: Gray
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. ... show more

    • Does everything I wanted it to do
Color: Gray
I had a digital lock going into our garage from the back yard which served its purpose for many years. I wanted to upgrade so: a) An automation could force it locked at night, b) I could unlock with my Apple watch (nice when I have gardening gloves on) and c) it could integrate with Home Assistant. The U100 did all of these. Install was easy with the hardest part being tucking in the wire from the outside part of the lock so that the inside part would sit flush with the door. The finger print reader is a bonus which works 80-90% of the time. I returned a different lock where the finger print reader would stop working hours after training it with my thumb. As far as what hub(s) are needed, the lock will connect via bluetooth with no hub and work when in BT range. It even paired with Apple's Home so that my Apple watch could unlock it. However there is a delay before BT connects. Adding an Aqara hub (I bought the M100), got most everything to function such as remote access, Home Assistant integration. To add my wife's Apple watch as a Home Key I had to share my Home setup to her phone. Apple much have changed something since the online instructions said I could just do that, but that option was not available. Apparently Apple now requires an Apple hub to share an Apple Home. I was going to purchase a Pod mini for general use, but want to wait for the 2nd generation. In the meantime I borrowed a friend's mini and confirmed that I can now share my Apple Home to get my wife's Apple watch to also work. I just installed my second U100 and will likely add a third. ... show more

    • Upgrade from Ultraloq U-Bolt Pro
Color: Gray
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. ... show more

    • Good quality, well designed smart door lock.

Overall this is an excelelnt product amd very good value. I chose it specifically for its Apple HomeKit integration and was not disappointed. The device itself is well made and designed and has “Apple like” quality. HomeKit integration was simple and quick via the QR code on the battery compartment. Some great features, especially the fingerprint reader which , so far, is flawless in functionality. Installation was largely straightforward until I got to attaching the battery on the back of the door. The two screws needed are ridiculously small and very fiddly to insert. Patience and a tiny screwdriver (not included) are required for this part. Recommended. ... show more
