Advanced Fingerprint Reader with Multiple Unlock Options
The U400 features a 160 Γ 160-pixel fingerprint sensor for fast and reliable recognition, unlocking in just 0.3 seconds with up to 98.6% accuracy and a false acceptance rate below 0.0001%. It securely stores up to 50 fingerprints on-device with AES encryption to ensure maximum privacy.

Long-Lasting Power with USB-C Backup
The Aqara U400 is powered by a rechargeable 4,880 mAh battery that can last up to six months on a single charge. A USB-C charging port on the panel allows for quick recharging. Voice prompts and a partially lit keypad notify you when the battery reaches 20%, and the UWB indicator light changes from green to yellow to signal low power.
For added convenience, the USB-C port supports emergency power from a power bank or any USB-C-to-USB-C compatible device, ensuring you never get locked out.
Weatherproof and BHMA Grade 3 Certified
The U400 smart door lock features an IP65-rated outer panel, protecting it against dust and heavy rain, and can operate in extreme temperatures as low as -35Β°C. This ensures reliable performance in any weather, whether indoors or outdoors.
With BHMA Grade 3 certification, one of the most recognized standards for door lock safety and performance, the U400 guarantees everyday security, durability, and lasting peace of mind.
Quiet Mode and Auto-Locking with Full Hub Access
The U400 smart lock features auto-locking, which engages automatically when the door closes using a built-in gyroscope. You can easily control this function via the app, the Action Button, or voice prompts.
A Do Not Disturb mode lets you lower volume and mute noncritical alerts for a quieter home. You can also create automations, such as turning on lights, air conditioning, or cameras when the door is unlocked. Integration with the Video Doorbell G410 allows you to see whoβs at the door and unlock in a single flow.
When paired with the Aqara Hub M100, the U400 acts as a Matter Controller, enabling:
- Remote control of locking and unlocking
- Adding periodic or temporary passwords remotely
- Checking battery level and lock status
- Creating automations
- Generating Matter pairing codes for integration with other compatible devices
- This setup provides full control, convenience, and smart automation for your door.
