Key switch replace?
« on: May 03, 2014, 11:02:05 pm »
1977 C10. My key switch falls out when I pull the key out. I looked at several in the wrecking yard and found they have a screw that goes through the slot on the bottom of the cylinder. My aluminum housing doesn't have a place for that screw.
What holds the key cylinder in place?

Early GM ignition tumblers in the column were retained by a spring loaded steel tang that was integral with the tumbler (e.g., LC14290).  The tang engaged a small slot or window in the housing that was about 3/8" long by about 3/32" wide.  Just as a guess - there maybe an issue with the locking tang or someone may have mismatched the tumbler and column.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Ya, my lock cylinder doesn't have a lock tang.
I think you may be right. I think the PO may have put the wrong cylinder in. My cylinder has a slot that would except a screw keeper. But the aluminum housing doesn't have a place to put the screw.
