Aqara Smart Lock U100, Fingerprint Door Lock with Apple Home Key, Keyless Entry Door Lock, Bluetooth Electronic Deadbolt Lock, IP65 Weatherproof, Supports Apple HomeKit, Alexa, IFTTT, Silver

Awesome lock especially if you are an Apple user. It has HomeKit integration, Apple Home Key, fingerprint reader, a numeric keypad AND a physical key! I mean wow. I have been using Yale locks for years and they have been a challenge with HomeKit not to mention the screen on the keypad scratches to the point that it's unusable. Ala in all the Aqara Smart Lock is a great piece of hardware and is simple to install. Highly rated.c

I love this lock. It's been installed for 7 months now and still working awesome despite being basically unshielded from rain or sun. Integrates with the Aqara M3 hub that is unfortunately required for the extra feature set, but once you get that setup you can go on further to add it to other smart home assistants and/or Home Assistant. I can have Google home lock the door for me, or I can use the Home Assistant app to control and view the status of the lock as well. The fingerprint works great as well as rotating codes that can be programmed for pet sitters or other temporary guests. I've had no connection issues and so far battery life is still reporting as "high" after 7 months, although this is used on a walkout basement door and not a primary entry for us. Having the fingerprint and code is great if we ever accidentally get locked out of the house. I definitely want to add more of these to our primary entry doors.

Our son recommended this lock. The lock itself was easy to install and fit in the existing deadbolt holes. The strike plate is larger and I had to buy chisels to enlarge the opening. After a first try the strike plate was set too far back and the lock would not shut. After chiseling some more to move it 1/8” it works fine. We really like the fingerprint to open when we have our hands full. We also really like the autolock capability and the way it works.

I am actually pretty happy with this lock - definitely an upgrade from the U50 I first ordered and returned because the programming was impossible to figure out, and it was kinda ugly. So I upgraded to try again. This lock is much classier - and the only reason I gave this U100 a 4 is that this one is also very difficult to set up/program. First, though - the mechanics. My husband easily installed the lock EXCEPT, save yourself some trouble - first thing measure the hole in your doorframe that the deadbolt slides into, before you do anything else, and compare to the measurement of the deadbolt plunger. It runs a bit long and the lock will not work if the plunger is blocked from full extension. If this happens the numbers on the outside will flash red and an alarm will sound TEN times and embarrass you in front of your neighbors 😉 and the lock will automatically unlock. You will not be able to make it stay locked, even by manually locking it - it will unlock itself again and again until you remove a battery. So just scrape the hole in a bit further if need be, and you’ll be fine. Other than that, physical install’s a cinch. It’s the programming that will have you pulling your hair out, especially if you’re trying to sync with HomeKit (which is the ENTIRE reason I abandoned a perfectly good wireless door lock that didn’t have HomeKit integration). Let me say first, you do NOT need to buy a hub to use HomeKit with this lock. Your HomeKit hub will do the job BUT the Aqara set up instructions are not user friendly, and make things infinitely harder! By the time you somehow get it working, you will no longer remember how you did it! One reviewer (and you’ll get better info reading these reviews and YouTube videos than the manufacturers written or online help file) mentioned not installing the Aqara app until after the lock is installed, and I did that, but that didn’t seem to help. For many of my numerous attempts to quit and start over, I tried to set up HomeKit with the little HomeKit button inside the battery compartment, but the instructions weren’t clear about whether I should use that BEFORE the Aqara set up button, or AFTER the Aqara set up bottom, or INSTEAD of the Aqara set up button. I kept taking out a battery and doing a full reset, and then trying another combination, which got SO confusing - but I kept trying. I think I finally left the HomeKit button alone and just used the Aqara set up button which prompted me to pair the lock in the Aqara app using the outside keypad. After that somehow (maybe with the HomeKit set up button?) I stumbled on to a page in the Aqara app that asked me to pair with HomeKit, and that’s where you scan the Apple QR code and it syncs with HomeKit properly. At that point everything finally worked, including the touch with my phone and watch. BUT my husband and our grandgirl are also included in our HomeKit through Family Share. Our granddaughter wasn’t even here when we set up the lock, but it added it to her HomeKit. (It also started driving her crazy sending notifications to her phone every time we locked or unlocked the door). It also added a HomeKey to her Apple Wallet, and also to my husband’s, but neither of them has been able to do the touch open. It’s been weeks, and suddenly yesterday a prompt popped up on her phone to add the touch entry. It happened so fast I just clicked on it and followed the prompts, and it set her up to touch her phone to the lock, and it works seamlessly. And she doesn’t even HAVE the Aqara app! But my husband’s phone - still nothing. So, IN SPITE OF THE AGGRAVATION, this lock is actually great. There are numerous ways to unlock the door, so the touch thing isn’t a deal breaker and it’ll pop up one day for hubby as well, I guess. What I want to say is, don’t give up! This seems a solid lock as far as keeping the house secure, and it’s clever. Hopefully Aqara will go step-by-step through their instructions & FAQ and write up a concise process for setting up the programming, and they’ll be a serious contender for the VERY few, much more expensive, Apple-enabled door locks available. It really shouldn’t be so hard to explain the set up. That’s the only downside to this lock - and probably to the more feature rich options as well. Do better with your documentation and you’ll have a real winner.

This lock has more features than more expensive big name locks. It’s solidly built and easy to install. You need to be sure the deadbolt lines up with the strike plate so it can move freely. That was the hardest part, but not a problem with the lock. HomeKit integration was the main selling point for me. It’s nice to unlock your door with your Apple Watch. The fingerprint sensor works really well. I just bought my third one for my last exterior door.
