Customer Ratings & Reviews

Upgraded from the U100 to the U400 and it’s a night and day difference. The build quality is a noticeable step up, and the new rechargeable battery pack is a huge improvement over swapping out AAs. Because it uses Thread, it's significantly faster and more responsive than the U100. The Apple Home UWB feature is the best part: it auto-unlocks entirely hands-free as you walk up. Highly recommend!

Easy install and setup and works great with my iPhone Air and Apple Watch Series 11. Walk right up to the door and it automatically unlocks. You also have the ability to share keys with other Apple users which is helpful for my kids. You can also utilize finger print and passcode. Has a rechargeable battery which is also a bonus as other locks I have used in the passed used regular AA batteries. Quality lock and highly recommend!

Ultra wide band is the differentiator on this smart lock. No other locks currently on the market offer the ease of simply being able to walk up to your door and have it unlock without you touching anything. Maybe a minor inconvenience for some, but this is clearly the future of all smart locks. Install is super easy as well, and the fact that it comes with a threads hub in this kit of the the icing on the cake. If you’re looking for the BEST lock available in 2026, this is it

The family loves this lock. The UWB technology is a game-changer; it opens as you approach the door. It offers multiple unlock options, including fingerprint, tap, and key. My only suggestion is that I wish it was made entirely of metal. For Android users, this lock should be compatible with Aliro when it launches, providing an Apple Homekey-like experience. I highly recommend this lock! You're welcome!

Having UWB is awesome. The door unlocks as a approach it. Granted, this only saves a few seconds vs using the fingerprint reader and/or typing in the code, but it is almost magical! Also, the lock mechanism is SO FAST! My old smart lock took 2-3 seconds to turn, this does it in about 1/2 second. Very cool

I have bought this for my new home. The installation was easy, and I love the smart features of Aqrar u400, and the compatibility of Matter.

Works great as long as the door is closed correctly. Fingerprint sensor is a bit hit or miss. UWB works very well, so it unlocks as I get close to the door (only from the outside), so happy with the locks. HomeKit integration works very well.

Love this new smart lock. With using my iPhone Air or Apple Watch Ultra, it automatically unlocks as I get close to it. I liked it more than my old Aqara lock that requires me to pull out my phone to unlock.

High quality lock. Includes a hub. Integrates well into the Apple world.

Easy install. Rekeying took a bit of time but happy to have the option to not switch keys. It’s been working well but we don’t use the front door often. So far so good. Looks good and no issues. It’s a little loud and a bit jarring when locking back but it may be an indicate issue (just our door). Will update if we have any issues.

Integrates well with AppleHome. unlocks on approach to front door. usually at the 1 foot mark

Very impressed with this UWB smart lock. Unlocks flawlessly when I approach. looks sleek and easy to install. it is a must buy for smart homes. a bit pricy though,.,but still worth it.

This lock works well. I had a little issue with it unlocking from inside. Their customer service was great. I had not connected the wire completely
