I have some more slot machine locks, they need keys from a customer.
Jennings & Co Yale locks. A Yale pin tumbler, I have the pinning kit, depths, it's been the same for decades. It's more difficult to separate the back from the front but it can be done.
Ace locks, I have the pinning kit, with keys. Easy peasy
Mills Bell locks, ever since I took two apart, it's been a breeze. Easy peasy.

Jennings & Company Yale, code starts out: ODJ

I have these locks finished, all keyed up.

I have just a few more to go, overall these were not all that bad to rekey.
Having Mills locks that were not hacked on makes the job easier. Actually, I can't do anything with the hacked Mills locks.
I have the pinning kits for the Yale locks, the only thing they slowed me down was having to shim the locks to take the the locks apart.
The ace locks were easy, I have a pinning kit.

All of these locks were sent to me to be keyed up for a customer. The rekey is $15.00 each, since it's a bulk lot, the keys are $3.00 each approximately.

I don't mind rekeying these locks, getting the job done correct is what really matters.

I am a locksmith, master safe and vault technician. I rekey locks for customers. I don't bugger up the locks, I actually disassembly them and rekey them correctly.

I have several more slot machine locks that need keys made. One is a DUO slot machine lock that needs a first fit key.

I have a bunch of Yale ODJ Jennings keys. Also several DUO keys. Maybe a number match? Let me know what you need, I might have the exact number.
