CHANGING CODE ON MODEL # 45891:
On the inside of the door toward the hinge, you will see a small red button. Press this button until the yellow light on the front control panel lights up. Now you can imput the new code (1 to 8 digits) into the front control panel, followed by either the "A" or "B" key. The safe will beep twice (2 times) to confirm the code has been changed. Important: If the safe beeps 3 times, then the code has not been accepted and you must repeat the above steps.
DO NOT LET THE BATTERIES RUN OUT BECAUSE YOU WILL NOT BE ABLE TO OPEN THE SAFE OR CHANGE BATTERIES.
