Maintenance
- Battery Replacement: When the low-power alarm sounds (10 beeps after unlocking), replace the 4 AA alkaline batteries promptly. Use only high-quality alkaline batteries for optimal performance and longevity.
- Cleaning: Wipe the keypad and lock body with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or liquid sprays directly on the lock, as these can damage the electronic components and finish.
- Physical Keys: Keep the physical keys in a safe, accessible location outside the property for emergency access.

Troubleshooting
- Fingerprint Not Recognized: Ensure your finger is clean and dry. Try re-registering your fingerprint if the issue persists. Ensure proper placement on the sensor.
- Keypad Not Responding: Check if the batteries are low or depleted. Replace batteries if necessary. Ensure no debris is obstructing the buttons.
- Lock Not Engaging/Disengaging: Verify that the door is properly aligned and not binding. Check for any physical obstructions in the door frame or strike plate. Ensure the latch is fully extended or retracted.
- Low Battery Warning: If the lock beeps 10 times after unlocking, replace all 4 AA alkaline batteries immediately to avoid loss of function.
- Forgotten User Code: If a user code is forgotten, you may need to reset the lock to factory settings and re-program all codes and fingerprints. Refer to the programming section (not detailed here, but typically found in a full manual) for specific reset procedures.
