Aqara Smart Lock U400 is a Matter-over-Thread deadbolt focused on hands-free Ultra-Wideband access. With a compatible iPhone or Apple Watch and the required Apple Home/Thread infrastructure, the lock can determine that an authorized user is genuinely approaching the door before triggering hands-free unlocking.
Aliro-certified, not only Aliro-ready
At CES 2026, Aqara introduced U400 as Aliro-ready. The source product record notes that in April 2026 Aqara announced that U400 had passed Aliro certification, so the English page uses the newer certification status rather than the launch-stage wording.
Apple UWB and Samsung Wallet
U400 supports Apple Home Key and hands-free UWB on compatible iPhone/Apple Watch devices. Aqara also announced Samsung Wallet Digital Home Key using Aliro NFC on compatible Galaxy devices and firmware. The source record does not assume Samsung UWB hands-free unlocking is available on every Samsung device; that must be checked at handover.
Fingerprint, PIN and backup access
Beyond UWB/Home Key, U400 supports fingerprint access, PINs, NFC, app/voice control and a mechanical key. The integrated fingerprint reader stores up to 50 fingerprints, and Aqara publishes recognition accuracy up to 98.6% with an approximate 0.3-second response time.
Matter over Thread infrastructure
To add U400 to a Matter ecosystem, a compatible Thread-enabled Matter Controller is required. The source record lists integration paths including Apple Home, Home Assistant, Google Home, Amazon Alexa and Samsung SmartThings, while the exact feature set depends on platform, firmware and account region.
Official and Vietnam retail model codes
Aqara documentation/certification referenced by the source record includes DL-D06E, DL-D16E, DL-D06D, DL-D16D, DL-D17D and DL-D15D. A Vietnam retail channel also uses DL-D14D for a U400 Deluxe Kit; the website keeps this as a separate Vietnam retail code and does not merge it into the global model list without matching Aqara documentation.
| Model group | Configuration |
|---|---|
| DL-D06E / DL-D16E | Lock + 1 battery |
| DL-D06D / DL-D16D | Lock + Hub M100 + 1 battery |
| DL-D17D / DL-D15D | Lock + 2 batteries |
| DL-D14D | Vietnam retail Deluxe Kit code; distributor confirmation required |
Battery, auto-lock and durability
U400 uses a rechargeable Li-ion battery with Aqara-published battery life up to approximately six months depending on conditions. USB-C supports charging/emergency power. An internal gyroscope is used to recognize door state for auto-lock without a separate contact sensor. The exterior side is rated IP65 in the source record.
Vietnam pricing
The AQARA 2026 source currently used by the project does not contain a confidently matched U400 price. The Vietnam retail references recorded in the source list U400 Kit DL-D06D at 6,990,000 VND and U400 Deluxe Kit DL-D14D at 7,190,000 VND. The website uses those amounts only for the matching retail codes.
Has U400 passed Aliro certification?
Yes. The source product record states that Aqara announced U400 had passed Aliro certification in April 2026.
Does Samsung Wallet always provide UWB hands-free unlocking on U400?
This should not be assumed. The source record specifically notes Samsung Wallet Aliro NFC support; UWB availability depends on the exact Samsung device and firmware and should be confirmed at deployment.
