Installation Guide

The HEI LIANG Fingerprint Door Lock is designed for easy installation. A screwdriver is typically the only tool required. Ensure your door thickness is between 30-55mm.

Step-by-Step Installation:

1. Prepare the Door: Ensure your door is compatible and the existing hardware is removed.
2. Install the Latch: Insert the latch into the door edge and secure it with screws. Ensure the latch bolt faces the correct direction for your door swing.
3. Install the Exterior Knob: Insert the exterior knob assembly through the door, ensuring the spindle rod is in a vertical position. The "UP" sign on the knob should be oriented correctly.
4. Install the Interior Knob: Align the interior knob with the exterior assembly. The "UP" sign on the interior knob must also be correctly oriented. Turn the adjustment arrow on the spindle rod with your thumb to point to the center point and the "UP" symbol before inserting it into the mounting base. Apply slight force to fully insert the back lock.
5. Secure the Knobs: Fasten the interior and exterior knobs together using the provided screws.
6. Test Functionality: After installation, test the mechanical operation of the lock before setting up electronic features.

Tip: When installing the inner knob, ensure both the outer and inner knobs are inserted according to the "UP" sign on the top for proper alignment and secure fitting. The spindle rod should be vertical. Adjust the arrow on the spindle rod to point to the center and the "UP" symbol before inserting it into the mounting base.

3. Anti-Peep Passcode

To prevent others from observing your passcode, you can enter random digits before or after your actual passcode. The lock will still recognize the correct sequence within the longer string of numbers.

Example: If your passcode is 123456, you can enter 987123456321. The lock will unlock.
