its an 84 745. ive wiggled the steering wheel, shifted in and out of park, squirted graphite lube in the lock. no joy. It wont even turn to the on position. I took the steering wheel off and then the snap ring. no help. Do you have to take off the ignition switch? how to do that ?

Take off the steering column half shells. There is a small set screw underneath holding the entire ignition key lock assy in position. Once loosened the lock assy will slide out. The ignition switch is just that a separate replaceable switch with connector right in the column. Most likely worn and jammed . Make sure you got battery disconnect during this repair and careful on that set screw don't loose or over tighten. Set screw head may be covered in paint or light coat of glue to hold in place. It is difficult to align with ignition key lock assy, look for detent in new switch purchased from Bavaria auto sport.
Most of this from memory, if you can't figure it put will post here a detailed procedure.

I remember you take off just the steering wheel and column bottom half cover, Philips screws.
The set screw (slot blade ) is glued or sealed over. Will be see from below,
The column, holds the switch in place. Mark,the new switch on the outside as to position of screw detent to allow installation and mating with key lock.
Best to wait until you get new switch and it will become obvious how to remove old switch.most likely the plastic coupling bwt key lock and switch has broken which is part of the new switch.

Greg,

Thats probably exactly what I needed. The paint over the set screw made it a mystery.

Thanks
