Aqara debuts one of the first-ever smart locks that unlocks automatically on approach

Aqara has unveiled the Smart Lock U400 at CES, and it’s designed to make getting into your home faster, easier and more secure. It’s one of the first smart locks to use Ultra-Wideband technology, which means your door can unlock automatically and accurately as you approach.

If you’re wondering how safe that actually is, UWB’s precise location tracking means the lock knows when you’re at the door, so it won’t unlock if you’re just walking past or inside the house. If hands-free unlocking worries you. there are also plenty of alternatives, including Apple Home Key in Apple Wallet, fingerprints, PIN codes, NFC cards, mobile apps, voice assistants or even a traditional key for emergencies. Digital keys can also be shared easily with other household members.

The Aqara Smart Lock U400 is available now for $269.99 and comes in black or silver. It’s currently exclusive to the US via Aqara’s website and Amazon, but we’re expecting UK pricing and availability to be announced soon.

The lock is also Matter-compatible and runs on Thread, so it integrates well with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. The lock can automatically secure itself after use thanks to a built-in gyroscope, and it’s built for outdoor life with an IP65 rating to handle rain, dust and tougher weather. Power comes from a rechargeable battery that lasts up to six months per charge.

It’s Aqara’s first smart lock launch since the Smart Lock U200 Lite earlier this year, but the U400 is already shaping up to be one of the best smart locks we’ve seen in a long time.
