The escutcheon has an index on it for changing the keys (just like a change index on a dial safe):
This is the setup key's change index lined up on the escutcheon:
Insert the change key on the back and turn it about 90 degrees:
Remove the setup key, insert the operator key and turn clockwise until it stops. Then remove the change key and the new operator key is set. Here is a pic of the bitting:
I think this is a pretty cool lock. I'd like to work on picking it but I can't see how to get started. There are a couple of commercial picks for it but it isn't clear how they work. They look like long disc detainer picks but I don't think that would work well on a lock like this because there won't be any feedback when the wheels are turned.
Hope you like the pics and enjoy the rest of your weekend.
