- Within 5 seconds, enter your desired 3-8 digit code on the keypad, then press the "#" button.

- Test the new code with the door open before closing it. Enter your code, then press "#". Turn the knob to confirm it opens.
Important: If the yellow light flashes and the safe beeps three times, the code was not set correctly. Repeat the steps.
