Locksmithing/Diebold 180-32 & knob worn out



I have an old round door Diebold safe that I'm trying to restore for personal use in my home. It is Approx 24"x 24"x 32"high and very heavy.
Its old, ugly, and of low value, so I'm doing all the work myself.
It has a Diebold 180-32 lock on it that's pretty worn and knob turns hard and scrapes. Their are two screws that hold down a strap for re-locker and one is stripped out in the aluminum back also. I would like to replace or repair this lock assembly.
I've never disassembled a safe lock before but it looks pretty simple to work on. Looks like I need to pull out a U shaped tad/key on end of shaft and unscrew plastic disk to get knob out to grease or re-bush knob at the very least.  

1. Is their a higher quality, modern mechanical replacement for this lock/knob that I could install?

2. Owners/service manual for the lock assembly to help in disassembling it so I don't break anything?

3. What change key does it need? I was unable to find one specifically for this on eBay. Will a S&G 6700 key fit if I file it a little?

Again, I will be doing all work myself as the safe isn't really worth anything and I enjoy projects like this.

Thanks - Jeff

Hi Jeff,

These locks haven't been available for years.   You can use one of the current mechanical locks to take the place of your lock.

Second problem - many of these Diebold locks used a 1/4" dial spindle.    These aren't available and only Diebold used them.    Current locks use a 5/16" spindle.    If the hole through the door is drilled for the 1/4" spindle, then it would have to be redrilled to accommodate the bigger spindle.    The hard plate (barrier material) is very drill resistant, so this isn't an easy task in many cases.

As far as "owners / service manuals"   there is no such thing.    Safes really aren't that difficult to operate, and it was expected that the end user would be given instructions when the safe was originally delivered, and the combination set for the first time.

A change key and instructions are available, though no longer from Diebold - cost is $50 to $75 (depends on current price from source), plus shipping & handling.    I doubt you will find this on EBay.     The standard 6700 series change key is not made to work with this lock.

As for the stripped out hole,   You may be able to use some metal epoxy repair to restore the threads for the relock hold back strap.    If not, you can possibly modify it to work slightly differently or remove it all together.    You can drill and tap the back cover of the lock to give you a mounting point for the strap, but you need to ensure that the screw does not extend into the lock causing operational problems.

Hope this helps somewhat.
