That really is interesting! From what I understand of what I saw, he puts the blank in and turns it pretty hard several times and the pins leave marks on the key. He files down where the marks are until the pins no longer leave marks, and at that point the lock should turn. Did I understand that correctly?
I'm embedding it here to make it easier for everyone to see.
Im doing a little online training course that may lead to a new job and stumbled upon this video of a new ford ignition key being cut.
Im posting it just because I find it interesting. Hes demonstrating on a one side key, I dont know what era that is.
They are all 1 sided keys just that Ford keys are cut to work either side.
As you see he only worked 1 side and installs it the same way each time to use the "cut" side of the key.
A trick you can use with Ford leys if you have 2 that use the same type key is to cut 1 side to work with 1 car/truck and cut the other side for the other car/truck this way you only carry 1 key for 2 cars/trucks.
BTW IIRC the early 60's Ford cars and maybe trucks used a 1 sided key like most other cars & trucks.
Thinking early Mustangs, Falcons & Comets.
