Safe Servicing

Editor’s Note: The following conversation is taken from Locksmith Ledger’s online discussion forums. Visit them at

I have a customer who inherited a safe from his late  grandmother and no one has the combination. I haven't done much safe work yet but I guess is as good a time as any to cut my teeth so to speak.

On the front is "KEEP/SAFE john d bush & co. inc. rochester n.y. 14625 u.s.a.'' On the case below the door is the number  R-3786 and on the door is 261184. The combination lock sounds like it only has two wheels and after both are contacted, turning the wheel meets with quite a bit of resistance. Any info, tips or suggestions greatly appreciated.

That was a john brush safe and is a Sentry. They have an 800 number at their site. You may be able to get combo from serial number but otherwise you will need to manipulate it open. It sounds like a straight tailpiece lock. You also should contact Elmer Howard and get his book that covers many Sentry safes. You may even call him as he is very helpful to newbies.

Thanks. I ended up drilling and it all worked so nicely, a great confidence builder for the first time. I’m investing in some new safe servicing tools and equipment and now I'm off to dig up some info from AMSEC for the next job.
