I have an old safe in an office cabinet marked "cole steel manuf." I want to change the combination - How?

Question

This is a combination file cabinet and small safe and it appears to have some sort of adjustment hole in the back of the safe door. Any help would be appreciated.

Answer 1

You're probably going to have to contact the manufacturer for assistance.  Or a safecracker.

Added in edit - or a locksmith.  (D'oh - I should have thought of that)
