I have about 100 pinned Sargent cylinders and cores with keyways such as KA, KB, KC and KE. A group of 50 of these are keyed/pinned but use an undetermined keyway. Is there a KD keyway?
I also have 50 brand new cores that might use KF key but I am not sure. The box has KF hand written on it. So I believe I need a KF key to check with and then begin the process of repinning them.
I have tried several local locksmiths but they simply don't seem to know.
Any input will be appreciated.
