ignition lock disassemble

[jimfulco]

Well I poked around on it for a while and finally got it apart. The tumbler retainer looks to be a thin piece of stamped metal that's staked to the plug. I can't deal with tiny staked things, so to the locksmith it goes.

I hope they keep the guy who designed that thing in a cage somewhere. Under the bezel, there's a washer. Under that, there are 2 small brass plungers in the right-hand edge of the cylinder housing that act as detents for the LOCK position. The uppermost of the 2 also blocks a nub on the plug from turning counter-clockwise past the ACC position. Depress that plunger and turn the plug (key all the way in) a fraction of an inch more so the sidebar* on the plug lines up with a 1/8"x3/8" slot on the right end of the housing. The nub will be above the plunger. Pull the key out a notch or two to disengage the key buzzer mechanism. The plug should now come out with the proper amount of wiggling, jiggling, and kind words. No small parts came flying out, so working inside the two-gallon ziploc bag wasn't necessary.

* The sidebar is gray metal with a brass cross-piece on both ends, but you'll only be able to see one end at this point.
