Important Notes & Installation/Password Guide:

Door Compatibility: This lock is designed for doors with a thickness between 30mm and 60mm (1.18" - 2.36"). 

Door Preparation: The installation area on your door must be at least 85mm (3.35 inches) wide. The gap between the door and the frame should be between 2mm and 5mm (0.08" - 0.2").

Password Setting Tip: Your code can be 2 to 4 digits long, using any keys except the "C" key. Important: The digits in your code should NOT be repeated (e.g., 1122 or 8888 is not allowed for security reasons). You can press the code numbers in any sequence to open.

How to Change Your Password:

Use a screwdriver to loosen and remove the four screws on the front panel. Carefully lift off the cover.

Press and hold the "C" (Clear/Reset) button. Using the included tweezers, remove the small red code tumblers and insert them into the slots corresponding to your desired new code numbers. (Blue tumblers are non-code pieces). Note: Ensure the beveled edge of each tumbler faces inward.

Replace the cover, align it properly, and tighten the four screws securely. Your new code is now set.
