A Smarter Way to Secure Your Home
The Aqara Smart Lock U300 is a user-friendly digital lock designed for simplicity and convenience. It offers multiple ways to unlock, including fingerprint, NFC, passcode, and Apple Home Keys*. This single-latch lever lock is easy to install—if your current lock is a similar one-hole design with just a latch, installation could be as simple as swapping out a few screws.
With Matter-over-Thread compatibility, the Aqara U300 works seamlessly with popular platforms that support the Matter standard**, like Apple HomeKit, Google Home, and Amazon Alexa. You can also manage it directly through the Aqara Home app***.
Built for durability, the U300 runs on 4 AA batteries and offers a battery life of up to 10 months. Its IPX4 waterproof rating makes it suitable for both indoor and outdoor use.
*Apple Home Key setup requires a 2-in-1 Apple Home Hub that acts as a Matter Controller and Thread Border Router, like the HomePod Mini.
**Additional hardware may be needed, such as the platform’s Matter Controller.
***For full remote access, an Aqara Hub M3 may be required, though basic features do not need a hub.
