The pairing failed because the phone did not join the lock's Wi-Fi module within the required time. Once the Wi-Fi module's activation period expires, the lock automatically exits pairing mode to save power.Operation Process:

1. Enter Menu: Press 1# → Enter your Administrator Password.
2. Reactivate WiFi Module: Press 1 (Administrator Setting) → Press 3 (WiFi Connection) to restart the pairing window.

• Reason: During installation, the metal rod (spindle) of the front lock was not fully aligned with the latch and back motor, or was not inserted vertically.
• Solution: Reinstall the lock according to the instructions. Ensure the square spindle is fully inserted and the back motor (inside mechanism) is positioned correctly.

Reason:

• Your finger is too dry, too wet, or greasy.
• The fingerprint entry was incomplete (e.g., only the center was recorded, but not the edges/sides).
• There is dirt or residue on the surface of the fingerprint module.

Solution:

• Clean the fingerprint area with a soft, dry cloth.
• Re-register the fingerprint: Ensure you record multiple angles and press your finger several times during the entry process to cover the entire surface of your fingertip.

Reason:

• Using standard batteries with a short lifespan.
• Poor battery contact at the terminals.
• High power consumption caused by heavy motor strain due to tight installation.

Solution:

• Use alkaline batteries and avoid low-quality brands with unstable voltage.
• Check if the battery contact springs are firmly compressed.
• Ensure the latch does not rub against the door frame.
• Consider using rechargeable lithium batteries as a replacement.

Reason:

• The door panel is tilted or misaligned.
• The strike plate hole position is offset.

Solution:

• Adjust the panel to ensure it is level and horizontal.
• Reposition the strike plate on the door frame to ensure smooth operation.
• Check if the latch is rubbing or scraping against the frame.

Network Connection: A poor network connection can cause significant lag when updating settings or sending commands via the app.Solution: Ensure your lock has a strong, stable Wi-Fi signal to minimize latency and ensure smooth operation.

Reason: The noise is usually caused by mechanical friction from a misaligned latch or mounting screws that are either too tight or too loose, creating internal tension.Solution:

• Check System Settings: Press 1# → Admin Password → 3 (System Setting) → 4 (Door Opening Direction). Ensure the setting matches your door's physical swing.
• Adjust Strike Plate: Slightly reposition or file the strike plate on the door frame to ensure the latch enters the hole smoothly without rubbing.
• Calibrate Screws: Check the mounting screws on the internal panel. If they are over-tightened, loosen them slightly to allow the motor and gears to move freely.
