1. Introduction
The Aqara Smart Lock U200 is designed to provide convenient and secure keyless entry to your home. It integrates with various smart home ecosystems through Matter over Thread technology, offering multiple unlocking methods and smart features.
2. Setup
2.1 Compatibility Check
Before installation, verify your door's lock cylinder compatibility. The U200 supports Euro profiles and select Scandi cylinders. For US deadbolt locks, ensure compatibility with backsets of 2-3/8" (60mm) and 2-3/4" (70mm).

The U200 requires a 2-in-1 Matter Controller and Thread Border Router for full functionality across various smart home ecosystems. Compatible devices include Aqara Hub M3, Apple HomePod, Apple TV 4K, Amazon Echo devices, Google Nest Hub, and Samsung SmartThings Hub.

2.2 Installation
The U200 is designed for hassle-free installation, often fitting over existing door locks without drilling or screwing. It is compatible with Euro profiles and select Scandi cylinders, as well as US single deadbolts.

For Euro Mortise Locks, ensure your cylinder is equipped with an Emergency Function. For US Deadbolt Locks, PH1 screwdriver is needed for installation.


2.3 Door Lock Calibration
After installation, close the door and unlock it. Then, press the Set button for 3 seconds to initiate calibration. The lock will automatically adjust its stroke. Ensure the knob operates smoothly after calibration.
2.4 Power Setup
The U200 lock is powered by a rechargeable Li-Ion battery. It is recommended to charge the battery for 3 hours the first time it is used. As an additional option, a power bank can be attached to the doorknob for convenient charging of the Smart Lock.

The keypad accommodates 1.5V AAA batteries and offers hard-wired powering capabilities. AAA batteries are not rechargeable, and a hardwired setup requires a 12V-24V AC or DC power supply.

3. Operating
3.1 Unlocking Methods
The U200 offers a variety of convenient unlocking methods:
- Apple Home Key: Unlock using your iPhone or Apple Watch (requires Apple 2-in-1 Matter controller & Border Router).

- Temporary Passwords: Generate one-time or periodic passwords for guests.

3.2 Quiet Unlock Mode
The U200 features a Quiet Unlock Mode, which allows the door to unlock slowly, reducing noise levels. This feature can be activated directly from the keypad and does not require a hub or Thread border router.

3.3 Auto Lock
Thanks to the built-in gyroscope, the U200 can remind you if the door is left open and automatically lock it after closure. This feature is available within the Aqara Home app (ensure firmware is updated).

3.4 App Integration
The Aqara Smart Lock U200 seamlessly integrates with the robust Matter platform and is compatible with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Aqara Home. With the Aqara Hub M3, you can enable remote unlock and set up automations.

4. Maintenance
4.1 Battery Life and Charging
The U200 lock's rechargeable Li-Ion battery provides up to 6 months of battery life (based on up to 8 daily unlocking and locking actions via fingerprint/NFC). The keypad uses 1.5V AAA batteries or can be hardwired. Monitor battery levels via the Aqara Home app.
4.2 Cleaning
To clean the lock and keypad, use a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish.
5. Troubleshooting
If the knob is not smooth after installation, slightly loosen the three screws on the mounting plate to prevent over-compressing the cylinder. If the knob does not turn smoothly after installation, please try reinstalling the unit.
For further troubleshooting, refer to the Aqara Home app's support section or the official Aqara website.
