Thank you for the photos, I have some follow up questions.
Are the combinations to the safes known right now? Are you familiar with the dialing procedure as far as Left Right Left and 4 times this way and 3 times this other way to such and such number, then turn the handle or wheel this way or that way?
Are the doors currently in what is known as "locked open" where the bolts are extending out of the sides of the doors and the doors cannot shut all the way? if so, then you could just call it a day. If the bolts are all retracted and the doors can be pushed shut all the way, then that might cause someone to be locked inside. You could just open the doors, then extend the bolts, spin the dials 4 or more times around to scramble the combinations, and call it a day, but then someone slamming the doors may bend a bolt.
There is a SAVTA (Safe And Vault Technicians Association) safe technician named Dan Wehrman near you in Madison, WI.
