You are mistaken my friend! It was a well known fact when this thread was started.It is now verified but this thread started unverified. It was a fair way into it before it was verified. Squawk is fine but too many Squawk and then check.
You may have to call a locksmith. Some have a key or pin that goes into a hole so the combination can be reset. Some locks have a secondary line offset from the Zero line that you would use in the process.Only key mine came with was the one to lock the dial, no instructions on changing the combination. I bought this safe 22 years ago, maybe something has changed.
