Locksmithing/resetting a combination


I have a safe with the combination but want to change it. Its a 3digit turn style one but can't figure it out. I looked all over but don't see a way to do it. No key or spot for one. And I can't move the dial when it's open.

Please help!!!


Hi Nikki,

Sorry but you haven't given me any actual info about the safe, to work from.

Based on your description, I would assume that you have a Sentry Safe or something similar.   If so, these are really not designed to change the combination.    While the wheels can be reversed or positions swapped, this will require disassembly of the lock.

Note:   I never recommend lock disassembly as a DIY project.    You should contact a local safe company to have the combination changed.    If the safe is small enough, you may be able to take it or just the door in, for service and combo changing.

If you would like more info about the safe, I will need to see what you actually have.

"IF" the reason that you need the combination changed is that the safe is locked and you don't have a working combination, then you will need to have it opened by a safe technician, and the combo either recovered or reset.

Check your yellow pages under "safes & vaults" for companies in your area.

hope this helps,
