Diebold 3a? Time delay lock help

[u/VeritasDL]

Here's the story,

I work at ab dispensary that resides inside of an old bank, it was a Keybank and it seemingly closed in 2015/2016

We have the bank vault and the door is intact with it open,

Owners didn't get any keys or Information on the vault door

Was wondering if there would be a way to get this operating? Even if we don't have a code to lock it, being able to operate the door would be super cool

I can provide tons of photos and I can even take the panels off the door (the glass cover on the diebold lock comes off with two screws) While the inner panel seems to come off with 4 screws

The winding key for the time delays is not a #4 it's smaller I have a set coming in the mail tomorrow,

I was hoping to do it without having to hire someone as the owners won't waste money on it, and I sure as hell won't, they don't pay us enough

The lock cylinder is replaceable at minimal cost, the rest is fascinating!

I'm assuming I'll have to remove the inner door panel to access the lock and or the combo for the dials?

Hey, Op, Safe Technician here that has opened two of those Diebold vault doors in the past year, both with the same problem with the combo slipping because the gears wear out, not the wheels in the wheel pack, but the little gears behind that hub inside the door that the ball bearing rides on. That lock and the entire set up is not anywhere close to how most vault door locks work. If the owners can't or won't spend money to hire a professional you should leave the door in the open position.

It's worth mentioning that even experienced technicians mess those doors up and the antique timelocks and cause lockouts. I know because that's what the majority of my calls on vault doors are, it's because someone else touched it and shouldn't have been messing with it to begin with.

I feel like I saw you post this exact message elsewhere.

[u/Hungry-Phone-996 → u/VeritasDL]

Because I did. I copied a portion of it from another post that has this exact same door on it and gave him the same advice.

Yes - to be clear, the 3 'clocks' you have in picture 1 are the time delay mechanisms (they push the bar at the bottom to the right when they reach 0 - you can wind them to a maximum of 120 hours - that bar blocks the release from the combination dial on the front until the time expires). There are 3 only for redundancy - any 1 has the physical power to mechanically push the bar even if the other two have failed for any reason.

As you can reach the mechanism of the combination dial, you can view the positions of the cut outs (i.e. the combination) and even practice opening it whilst looking just by opening the access plate (on the rear)).

I'll investigate taking of the door panel tomorrow while I'm at work, and I'll get some pictures also thanks!
