I had the same issue years ago, I called the locksmith, he said he was busy and was going to tell me how to get it open myself. He said dial combo, then slam handle as hard as you could to the left (close) and it will open. I tried this like a dozen times and it didn't work. He came over, this guy was like 6'6" and 400 lbs. He said watch, I gave him the combo, he slammed it and the safe opened. He said the good news is your safe is open, the bad news is I have to charge you $50 for a device call!
