Aqara has rolled out the U400, the first smart lock to feature Ultra Wideband Home Key support, redefining convenience for homeowners.

The lock ships with a rechargeable battery pack, a backlit keypad, and fingerprint scanner, all housed in a modest design that balances form with function.

Installation takes under fifteen minutes, and the U400 connects via Thread, letting users add it directly to Apple Home for seamless control.

With reliable auto‑lock and Apple Home integration, Aqara’s U400 delivers a level of security and ease that other smart locks struggle to match.
