I’m only ten years away from retirement and am no longer up to the task of getting into big safes. However, I can still sort out smaller safes where the key has been lost.
I can also service your safe in order that you don’t get a nasty surprise one day and find yourself no longer able to open it.
Combinations for mechanical combination dials can be properly changed. (There is a sinister feature called the forbidden zone with “proper” combination locks (the kind you see in the movies)! And if you have lost your original instructions on how to change the combination safely, without locking yourself out, then perhaps you should ask us to help you.)
