Anyone familiar with US Navy Yale pin-tumbler padlock codes?
I have two 830s with some rather odd codes; UE71803 and UE91287. Obviously, these don't track with the normal Yale codes, which end st 29000 and change. These are J-series keyway small pins, so it's not a direct bitting. Have heard of adding 3 to each number & cutting as a direct bitting; that did not work in this case. Picked open, so they do work;keyway too small to get a good measurement on pins other than #1.
Impressioning has thus far been unsuccessful, and my blank supply is limited. Any help is greatly appreciated!
