About This

  • True Hands-Free Unlocking with UWB Technology: Experience a new era of smart access — UWB (Ultra-Wideband) detects your incoming presence, direction, and intent to unlock automatically as you approach. It provides a faster, more convenient, and highly secure way to enter your home without touching the lock. Perfect when your hands are full, you're wearing gloves, or arriving in the rain. (Note: UWB unlocking requires a Thread-enabled Apple Home hub and is supported on Apple Watch Series 6 or later (excluding SE) running watchOS 11.5+ and iPhone 11 or later (excluding iPhone SE & iPhone 16e) running iOS 18.5+.)
  • All-in-One Unlocking Options: Enjoy Apple home key tap-to-unlock (requires an Apple Thread-enabled Matter controller: HomePod 2nd Gen, HomePod mini, or Apple TV 4K 2021/2022), plus fingerprint, touchscreen passcode, voice assistant control, app remote access, NFC card support (card sold separately), and a physical key, giving you flexible, reliable ways to enter your home in any situation.
  • Matter Over Thread for Multi-Ecosystem Compatibility: Built with Matter over Thread, the U400 can connect to multiple smart home platforms simultaneously, allowing you to enjoy the unique features of each ecosystem. Thread offers faster response, more stable connectivity, lower power consumption, and secure data transmission. Note: A Thread-enabled Matter controller from each ecosystem is required for its respective platform.
  • Convenient Rechargeable Power System: Powered by a rechargeable and removable lithium battery that lasts up to 6 months per charge. Use the lock's USB-C port to recharge without taking the lock offline, or remove the battery and charge it separately. A low-battery voice alert will notify you when the battery drops below 20%, ensuring you never get caught off guard.
  • Certified Security & Outdoor Durability: BHMA-certified for proven protection, mechanical strength, and long-term reliability. The IP65-rated exterior guards against dust and water for dependable outdoor performance. Plus, the rekeyable design allows you to change the physical key without replacing the entire lock cylinder.
  • Unlock More Features with the Aqara App: Customize your security with Auto Lock, Night Latch Mode (only admins and physical keys can unlock at night), and Do Not Disturb Mode. Integrates seamlessly with Aqara cameras like the G5 Pro and G410 doorbell, allowing you to view visitors and unlock directly via live video interaction.
