4.1. Fingerprint Unlock
The smart lock features 360° fingerprint recognition for fast unlocking in 0.5 seconds. It can store up to 120 fingerprints.

Utilize the anti-peep virtual password feature to prevent others from guessing your code. You can input any random numbers before or after your actual password. The keypad is backlit for easy use at night.

4.4. TTLock App Control
The TTLock App allows you to manage your lock from anywhere. Features include monitoring lock status (remaining power, alerts), sending eKeys to other TTLock users, generating passcodes, managing fingerprints, and viewing operation logs. For remote control functionality, the CATCHFACE WiFi Gateway (sold separately, ASIN: B085HFFF9T) is required.

5. Maintenance
To ensure optimal performance and longevity of your CATCHFACE Smart Lock, regular maintenance is recommended.
5.1. Battery Replacement
The smart lock is powered by 4 AAA alkaline batteries. The TTLock App will provide a low battery alarm when the power is critically low (below 20%).

5.2. Emergency Power and Backup Keys
In case the battery is completely drained, you can use the micro USB emergency power interface with a power bank for temporary power supply, or use one of the two included physical backup keys to open the door.
6. Troubleshooting
If you encounter any issues with your CATCHFACE Smart Lock, please refer to the following common solutions:
- Lock Not Responding: Check battery levels. If low, use the micro USB emergency power or backup key.
- Fingerprint Not Recognized: Ensure your finger is clean and dry. Try re-registering your fingerprint if issues persist.
- Password Entry Issues: Ensure you are entering the correct password. The anti-peep feature allows extra digits, but the core password must be correct.
- App Connectivity Problems: Ensure Bluetooth is enabled on your smartphone. If using remote features, verify your CATCHFACE WiFi Gateway is properly connected and online.
- Door Not Locking/Unlocking Properly: Check for any obstructions in the door frame or latch. Ensure the lock is correctly aligned and installed.
For persistent issues, please contact CATCHFACE customer support.
