6. Troubleshooting Common Issues
Problem: The lock does not respond to the keypad.
- Fix: Check batteries. If the batteries are dead, use the emergency terminals. Connect a 9V battery (or power bank via USB) to the bottom of the exterior unit to power the lock temporarily.
Problem: Fingerprint is not recognized.
- Fix: Ensure your finger is clean and dry. The Z3 sensor is optical; moisture or oil can cause errors. Try enrolling the same finger at different angles to improve recognition.
Problem: The lock beeps continuously or keypad flashes red.
- Fix: This usually indicates a "Door Ajar" alert (the door isn't fully closed against the frame) or a low battery warning. Replace batteries immediately.
