I purchased an executive digital safe on craigslist. the guy opened it and it worked till i tried at home. How do you reset a combination on a Executive digital safe?

To reset the combination on an Executive digital safe, first, locate the reset button, usually found inside the door or on the back of the keypad. Open the safe using the current combination, press and hold the reset button until you hear a beep, then enter your new desired combination and press the “#” key to confirm. Make sure to test the new combination several times to ensure it's set correctly. If you’re unable to access the safe, refer to the user manual or contact the manufacturer for specific instructions.
