Re: Ignition Lock Cylinder Removal Questioin
You did not say what model Jeep you are working with.... But, I've faced this problem with 82-86 CJ's. If you happen to be working with the same, or something similar, here's what I found. My manual was less-than-clear. It seemed to have an 'arrow' that pointed to something I couldn't figure out, for the 'release' of the ignition lock cylinder. I only discovered the 'trick' by accident, on another column in the junk yard. There is supposed to be an access hole to poke through, where the arrow points in the manual. What the manual did not mention is that the access hole could have casting-flashing cast over it. It's kind of like a 'knock-out'. As soon as you knock out the access hole, you can access the release on the lock cylinder. You might need to ask a locksmith about this, or go look at more columns at the junk yard.
BTW, I do not remember it as a 'lock-screw'. I think it is something you push on. But, don't trust my memory.
