We picked this up to replace an older smart lock that finally gave out. Installation was pretty straightforward, though I didn’t find a physical manual in the box. Instead, I had to scan a QR code to access their website, where they walk you through the process with a video. It’s easy to follow—just take your time and you’ll be fine.One thing that did bug me: yet another app download. It feels like every device these days comes with its own app just to do one job. Still, in this case, the app is essential—there’s really no way around it.I’ve run into a couple of hiccups with smart home integration. I use the Samsung SmartThings app for most of my devices. While I see other models from this brand listed there, this particular model doesn’t show up. It looks like I’ll need to buy a separate hub to connect it, which I’m hoping resolves the issue. It would be disappointing if I can’t sync it with the rest of my setup.That said, the lock itself has been great so far. The mechanism is quiet and fast—much better than my old Kwikset, which made a loud, drawn-out grinding noise every time it locked or unlocked. This one gets the job done quickly and cleanly.I’ll try to post an update after some time. Living in Southern Arizona, I’m especially curious to see how well it holds up in the desert heat and sun.

FYI: I'm judging this lock based on both my experience with it so far AND in comparison to our Level Lock Plus, which is the "other" Apple Home Key compatible lock.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.

I have three of these locks installed in my home, and they have proven to be a reliable and cost-effective choice for Home Key-compatible smart locks.Pros:- Seamless Home Key integration: Unlocking the door is effortless—simply tapping an Apple Watch or iPhone provides consistent and reliable access, even when carrying items.- Aesthetically pleasing design: The lock has a clean, modern appearance that blends well with various home styles.- Multiple access methods: Users have a range of options, including a traditional key, fingerprint recognition, numerical code entry, Home Key functionality, and app-based control.- Compact size: The lock does not protrude excessively, maintaining a sleek and unobtrusive profile on the door.- Good battery life: Battery performance appears reliable, reducing the need for frequent replacements or recharges.Considerations:- Connectivity requirements: Optimal performance requires an Apple HomeKit-compatible device such as an Apple TV, HomePod, or Aqara hub. Without one of these, connectivity is limited to Bluetooth via the Aqara app, restricting remote access.- Fingerprint sensor reliability: The fingerprint reader’s performance can be inconsistent, though this may be less of a concern for those primarily relying on Home Key.- Durability concerns: While the overall construction appears solid, the keyhole cover is noticeably lower in quality compared to the rest of the lock.Final Thoughts:Given its affordability, performance, and integration within my existing Aqara and HomeKit ecosystem, I would consider purchasing these locks again. However, those without a compatible smart home setup may need to evaluate whether the connectivity limitations align with their needs.
