True Hands-Free Unlocking with UWB

The Aqara UWB Smart Lock U400 brings true hands-free access to your home. This Aqara smart lock U400 uses UWB (Ultra-Wideband) to sense when you arrive and unlock as you approach. It reads distance and direction for fast and secure entry. No touch needed. This makes it one of the best smart locks for home use, especially when your hands are full, you wear gloves, or it is raining.

[Note: UWB unlock requires a Thread-enabled Apple Home hub. Supported on Apple Watch Series 6 or later (excluding SE) with watchOS 11.5+ and iPhone 11 or later (excluding iPhone SE & 16e) with iOS 18.5+.]

All-in-One Unlocking Options

This Aqara smart lock gives you many easy ways to unlock. Use Apple Home Key with a simple tap. Unlock with fingerprint, touchscreen passcode, voice control, or the mobile Aqara Home App. NFC card access is supported (card sold separately). A physical key is also included. This flexibility makes it a great smart lock for apartment living and busy homes.

Apple Home Key requires a Thread-enabled Matter controller such as HomePod (2nd Gen), HomePod mini, or Apple TV 4K (2021/2022).

Matter Smart Lock with Thread Support

Built as a Matter smart lock, the Aqara Smart Lock U400 works across Apple Home, Alexa, Google Home, and Home Assistant at the same time. Matter over Thread delivers faster response, strong reliability, low power use, and secure local control. This makes it one of the best smart locks for Home Assistant and modern smart homes.
Each platform requires its own Thread-enabled Matter controller.
