Product Description
Aqara Smart Lock U400 Kit is one of the world’s first Apple UWB smart locks, using cutting-edge Ultra-Wideband to precisely sense when you approach so your iPhone or Apple Watch becomes a hands-free Apple home key that unlocks the door with no tapping or codes, while native Matter over Thread compatibility ensures effortless integration across ecosystems, and its long-lasting rechargeable battery, IP65 waterproof rating with BHMA-certified hardware, advanced fingerprint reader, and auto lock assurance combine convenience, security, and durability in one sleek, ultra-secure, and effortlessly connected smart lock.
Key Features
Hands-Free Unlock with Ultra Wideband (UWB): Experience next-level convenience and security with spatially aware UWB. Simply approach with your UWB-enabled iPhone or Apple Watch and the door unlocks instantly. No tapping, swiping, or entering codes required. UWB enables more precise and secure detection for a private, truly hands-free entry with no biometric checks. As Aliro rolls out, this convenience will extend to more devices across different ecosystems.
Advanced Fingerprint Reader: 160×160 pixel sensor for fast, reliable recognition; unlocks in 0.3 seconds with up to 98.6% accuracy and a false acceptance rate below 0.0001%. Stores up to 50 fingerprints securely with on-device AES encryption for maximum privacy.
Future-Proof Access Across Ecosystems: Powered by Matter over Thread, the U400 works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and other Matter-compatible platforms for stable, reliable performance. As the Aliro digital key standard rolls out, more phones and wearables will be able to unlock the door, so you are not tied to a single brand or device.
NFC & Other Benefits of Home Keys: Tap to unlock with Apple home key in Apple Wallet using near field communication on iPhone or Apple Watch, works even when the device is powered off on supported models with Power Reserve, and allows remote key sharing and time-limited guest codes for secure, convenient access.
More ways to get in, even without your phone: Uses the keypad with anti-peep and offline one-time or scheduled guest codes, tap an NFC card, unlock from supported apps, ask Siri or Alexa, unlock with preset automation, or use the backup physical key with re-key support.
Long-Lasting Power with USB-C Backup: Rechargeable 4880 mAh battery lasts up to 6 months per charge, easy USB-C charging on the panel, clear low-battery alerts at 20 percent with voice prompts and a half-lit keypad, plus USB-C emergency power from a power bank or any phone that supports USB-C to USB-C charging so you never get locked out.
Weatherproof and BHMA 3: IP65-rated outer panel resists dust and heavy rain, and BHMA (Builders Hardware Manufacturers Association) Grade 3 certification provides trusted everyday security and lasting durability.
Smart Locking, Quiet Mode, and Seamless Automations: Auto lock engages when the door closes using a built-in gyroscope, with easy on or off from the app or the Action Button with voice prompts; Do Not Disturb mode lowers volume and mutes noncritical prompts for a quieter home; create automations to turn on lights, air conditioning, or cameras when you unlock; and integrate with the Video Doorbell G410 to see who is at the door and unlock in one flow.
Smart Lock U400 Kit Includes Hub M100: The Hub M100 can be paired with the U400 as an Aqara Matter Controller, enabling remote control (locking/unlocking, adding remote periodic passwords, checking battery level and lock status) within Aqara Home, automation, and generating Matter pairing codes to integrate with more ecosystem devices.
