Product Description

Powered by advanced UWB technology, the Aqara Smart Lock U400 transforms your phone into a proximity-based digital key. No taps, no codes—just approach, and the lock verifies your presence in real time, unlocking with pinpoint accuracy. The future of seamless, intelligent access starts here.
Features
Hands-Free, Instant Unlock
Still struggling to find your keys or pull out your phone? UWB frees your hands. Whether you're carrying heavy bags in the rain or holding your child, you can walk right in effortlessly. Powered by Ultra-Wideband (UWB) technology, it achieves centimeter-level precision by measuring Time of Flight (TOF) and Angle of Arrival (AOA), ensuring seamless and secure access.
Smart Intent Recognition
UWB technology helps track your movement trajectory, speed, and direction. The door unlocks only when you approach the lock in a stable, intentional path. Simply passing by or lingering near the door won’t trigger an unlock.
One-Way Unlock Protection – No Accidental Unlocking from Indoors
Worried that your child might accidentally unlock the door while playing with a phone in the living room? No worries. The smart lock detects when you’re inside and prevents unintended unlocking. Its precise positioning system ensures security for you and your family.
One-Tap Sharing for a Seamless "Hands-Free Unlock" Experience – Enjoy Cutting-Edge Tech as a Family
Easily share door lock access via Apple Home family group. Your family and friends don’t need to register an account or pair any devices—once they accept the invitation, their UWB unlocking capability is automatically synced.
Unlock Your Door Like Unlocking Your Phone
Equipped with a 160×160 resolution fingerprint amodule, featuring a sensor area 75% larger than popular solutions on the market. This ensures higher sensitivity, eliminating unresponsive issues and delivering a stable and reliable unlocking experience.
The Ultimate Apple Ecosystem: UWB + HomeKey + Guest Passcodes
Seamlessly integrate with Apple’s ecosystem—add family and friends in the Home app for a shared UWB unlocking experience. Need to grant access to a housekeeper? Set up recurring passcodes effortlessly. Plus, U400 supports Matter OTA updates, allowing users to enjoy the latest features without connecting to Aqara Home.
Matter Integrates the Strengths of Multiple Platforms

Aqara focuses on deep platform integration and strong third-party compatibility for a seamless experience. After a Matter user binds the smart lock, it automatically starts guided calibration. Fingerprints can be added in the Aqara Home app or directly on the device for intuitive unlocking. seamlessly.
