Gordon,
I got several of the locks that were new but without keys. I took a couple apart and they were the same wheel numbers and in the same order so I set out to make a key or two.
I charted each wheel to see what the true wheel numbers would be. I then made a chart of good wheel combos and what the working key cuts would be.
I picked a simple one to start. A key with a straight cut down the center ( a # 4 cut out of 7) would work with a valid wheel combo.
I made one by hand out of aluminum stock because it was easy to work with. I filed and scraped the blank until I had a working key. It was rough but it does work. I then set out to make a more secure key with different cut at every position. Again working in aluminum, I was able to make a key that would work but it too was rough due to the hand work.
I made some brass blanks but found that I can not work them by hand. I need to use a drill press with a X-Y table or some type of milling machine. I have not yet been able to find anything to use. I hope that good machining will produce a better key with smoother cuts.
Thanks for you write ups on these locks. I thing they are very clever. I understand from Realtors that used them that they would gum up and be hard to operate and many sales people carried a can of silicone to lube the locks. I think the cost of the locks and the high maintenance led them to be replaced.
Thanks again.....
Steve

@ escapenrv Let us know how you make out with this keep us posted please !

I have 5 or so of these locks, new and never used. I will trade or buy one or more keys for them.
I hand made 2 keys from aluminum. One is a bitting like 33333 and it works in my locks. The other is a varied bitting. I decoded the wheels in my locks to see what were valid key codes and then scraped the groove in an aluminum blank that I made. These were so much work and time needed to make that I did not make anymore or try to make one in brass.
I would like to get a key or two so I can demo the lock to others. I will trade the others if anyone is interested.
Send me an email...that is the fastest way to reach me.
Thanks
Steve Garrett

If anyone else needs keys for these locks drop me a PM.

Vatorfxr - joined up so I could reach out to you for some help with my Multacc Lock - I'm fascinated by this lock and would like to decode and create a key and decipher the combinations. Seems like I just need to work thru the hasp combo - there are a few vids on how to do that - it's not as easy for me as it looks for everyone else but I'll stick with it and figure it out. Worst case I can open up the back and see what the wheel true gates are and I'll be fine. I'm excited to decipher the film punches to get a working front combination. BUT - I'm not sure how to derive the bitting on the operator Key? I'll try to PM you again if I can figure that out....doesn't bode well for figuring out the lock if I can figure out the messaging function...

I've made an OpenSCAD file which can generate MultAcc keys with arbitrary bittings, based on Gordon's bitting data and SgrA*'s prior work. You can generate either solid models or a split model that allows you to glue a strip of metal into the head for reinforcement. If you know the order of the different types of code wheels for your box, you can lookup the combination for a specific bitting (or vice versa) on my site https://prevarikation.com/locks/multacc/#combination-lookup.

I've 3D printed some different bittings and 4 out of the 5 work, so it's worth a shot if you're without a key. Known working bittings include 44444, 17171, 53665.
