If you know the combination:

1) Turn the dial to the left a few complete rounds, then stop on 1st number.
2) Turning the dial to the right, pass up the 2nd number once, then stop on it on the next round.
3) Turn the dial to the left directly to the 3rd number then stop.

The handle should open now.

I finally ignored the poorly-written instructions for programming a personal code and simply entered the factory code first and then pressed the prog/enter code button.  The safe opened.  The instructions tell you to push the prog/enter code first and then enter the factory code or personal code to open the safe.  Wrong!  Do it my way should this problem happen to you.

Being a master locksmith we see this problem all the time on the Sentry Safe F3300 What happens is this Sentry Safe has a waterproof seal that sticks the door shut to prevent watter damage. But in doing so makes it seem like it will not open. We suggest pushing down on the left rear corner to pop the front of the lid open
