Combination Key Safe

We have a combination of old keys safe with two vertical rows of five pins each (1-5 and 6-0). You can not use any number more than once. We can not find the combination. Any ideas on how to open it?

On TV, they usually drill holes and use nitro. LOL

If you are the rightful owner, and the model number and serial number, you can call the manufacturer. If the original combination was not changed, they mioght help. It would be helpful if when you called, you had a gift locksmith!

Speaking of locks, a local locksmith may be able to open it. The cost should be less than $ 100 + tax.
