Aqara’s U400 now supports Samsung’s Home Key.

The smart lock, which launched earlier this year with support for Apple’s Home Key, is the first to work with Samsung’s new Digital Home Key.

The feature uses NFC powered by the new smart lock standard Aliro and lets you unlock your door by tapping your Samsung Galaxy smartphone on the lock. Aqara says UWB-based, hands-free unlocking is coming in Q2 2026.
