If the safe is brand new.. you must first remove the locking screw at the base of the combination lock dial
lockcase.. discard the screw.. Make sure you have the owners manual with the sticker and default lock code nearby before locking the safe.
The factory has a preset combination code that cannot be
deleted. It is on the owners manual. You can use that code if your codes have become compromised.
Also ensure the batteries are fresh. This may also be the problem.
Anything beyond this will require
assistance from Sentry. Your serial number is on the side of the door. Have that ready.
