I'm trying to change out a key start, solenoid-starter-type ignition switch. It appears to be the stock 1952 GMC switch and I can't figure out the correct formula to remove the lock cylinder which needs to come out first before removing the switch bezel and hence the switch. There are 2 holes in the lock face to insert wires, drill bits, etc. My GMC shop manual gives no removal instructions and Chevy instructions haven't worked so far. Any suggestions on the proper removal sequence would be greatly appreciated! Thanks.
Yes - I just did this with my 53 3600 and it only worked after turning clockwise after doing the paper clip maneuver. And my key switch only had one paper clip hole...
I still have the original key for my 1952 Chevy 1/2 ton truck. The positions on my ignition switch don't seem to agree with any descriptions I read on replace the key portion only. my key goes in with teeth pointing up. 45* left of straight up and down is the "OFF" position. Key straight up and down (teeth facing up) is the "ON/START" position, and 45* to the right is I guess "ACCESSORIES"-gauges on truck will not start. The face of the lock has two holes. I bought a new insert and keys, but have not tried to remove the cylinder yet. I will review the provided "tech tip" link. Any further suggestions appreciated. Brad
Brad - Just a my $.02 worth, but it sounds like your ignition switch is installed upside down.
Below are snapshots from a 1952 Truck owners Manual describing the ignition switch location, position and functions. The description of switch operation sounds like yours is 180 degrees off. Your switch also shouldn't have a third position according to the owners manual, so maybe replaced at some point in the past???

Dan, I wondered about that. I have the shop manual and owners manual, and will take a close look. I will not feel so bad replacing the switch then. I will miss that old very worn and thin brass key that I got with the truck in 1973. I will replace it this weekend. I hope it come off easier than nearly every bolt or screw I attempt to remove. (I will search a thread about that later!) Thanks, Brad
