Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Is your safe a dial-type, or one with a keypad?
Does it also, perhaps, have a keylock, perhaps under a sliding hatch or cover?
Then that's a tough case.
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
I am sorry to say that breaking this safe open may be the only remedy for the problem.
I'm not much at safe-cracking techniques, so I have Opted Out of this case. That opens the case to other Experts, in case another wishes to offer other advice, or further help.
