How do you unlock a gun safe that you don't know the combo too?

Study this. You will need good light and maybe a magnifying glass but you can read the old combination (It won't be cut a way like in the video). It would be dialing and recording #s.

Easier would to have a change key but it can be done this way. Do it all the time.

My buddy has a 100 year old safe in his barn. For the longest it sat door open because he did not have a combo. One day I was waiting for him to come home I took off the inside plate. Seems like there may have been two.
In about 45
Min I had the combo figured out. When you can see the mechanism it's not that hard to do.
So, if you can open it up I bet you can do it yourself
