Key Features

• Hands-Free Unlock with Ultra-Wideband (UWB): Enjoy next-level convenience and security with spatially aware UWB technology. Simply approach your door with a compatible iPhone or Apple Watch, and it unlocks instantly. No interaction required. UWB delivers more precise and secure detection, keeping your entry private and seamless. As the Aliro digital key standard rolls out, this experience will expand to more devices across ecosystems¹ .
• Advanced Fingerprint Reader: Unlock in just 0.3 seconds with a 160 × 160 pixel sensor offering up to 98.6% accuracy and an ultra-low false acceptance rate below 0.0001%. Store up to 50 fingerprints, all secured locally with AES encryption for maximum privacy² .
• Future-Proof Access Across Ecosystems: Powered by Matter over Thread, the U400 works reliably with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and other Matter-compatible platforms. You are not locked into one brand or device — your smart home stays flexible and future-ready.
• NFC & Apple Home Key Benefits: Tap to unlock using Apple Home Key via NFC on your iPhone or Apple Watch. Supported models work even when powered off, thanks to Power Reserve. Share keys remotely or create time-limited guest access for added convenience and control³ .
• Multiple Ways to Unlock: Access your home using the anti-peep keypad, offline one-time or scheduled guest codes, an NFC card, supported apps, Siri or Alexa, preset automations, or the backup physical key with re-key support.
• Long-Lasting Power with USB-C Backup: The 4,880mAh rechargeable battery lasts up to 6 months per charge. Recharge easily via USB-C on the lock panel. Receive clear low-battery alerts at 20%, including voice prompts and keypad indicators. If needed, use USB-C emergency power from a power bank or compatible phone—no lockouts.
• Weatherproof & BHMA Grade 3 Certified: The IP65-rated exterior resists dust and heavy rain, while BHMA Grade 3 certification ensures trusted everyday security and long-term durability.
• Smart Locking, Quiet Mode & Powerful Automations: Auto-lock engages when the door closes using a built-in gyroscope. Enable or disable it easily via the app or Action Button. Do Not Disturb mode reduces sounds for a quieter home. Create automations to trigger lights, climate control, or cameras when you unlock, and pair with the Video Doorbell G410 to see who’s outside and unlock in one smooth flow.
