I spent 15 minutes this morning trying to get my in key to turn the ignition switch. Finally got started and got to work. Turned off just fine.

I know that I will need to replace parts here. I don't want to fight this battle every morning. Should I plan on replacing the key cylinder, the ignition housing, the ignition switch, or a combintation of those parts?

If I replace the key, I'll do the door locks at the same time.

I have had good luck spraying a small amount of wd-40 on the key and working it in and out of the lock to lube the tumblers. Can't hurt

I did that. I prefer teflon lubricant that I use on my bicycle parts, but I didn't have any handy, so used WD40. This morning it was much easier, but It's been easy before.

This week I will try to take it all apart and lube and see if I can find the catch. This truck sat out in the sand and dirt for 14 years gathering grit in every movable part. I'm slowly working through items as I need to for daily driving.

Ignition switch is fairly easy to disassemble. I pulled mine apart and let it soak in contact cleaner for a few days, then blew it out with an air hose. I rang it out with a meter and made sure nothing was shorted.

While you have it apart,clean the tumblers with carb cleaner since there is no electrical stuff involved in those,and then lube them up again.Small precaution,and could just solve the problem.

I love carb cleaner.
Thanks for the reminder pay attention to every moving part. Maybe I'll get the switch out this weekend. For now, It hasn't siezed since the WD40, so I'm just slowly grinding away with the grit that is trapped inside of the switch.
