Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please tell me the maker and model of your safe.
It may need lubrication ( a special type made for safes - not just any type. Lubricants of the wrong type can gum up a lock. In fact, if that was already done, it could explain the problem you are asking about. ) But tell me the model # ***** maker, first, before I advise you further. Thanks.
