got a few minutes to remove ignition yesterday after work. entire process took me about ten min start to finish, including pix. i didnt remove bottom cover, but it would probably be easier if you did.
put ignition in on position and stuck a #1 phillips screwdriver into the guide hole. once i hit the little ballbearing deal that holds it in place the ignition slide right out no issues. took it inside for some better light and could see the little nub i had pushed down the other day. turned it over and it fell right out. ended up being orange, not pink.
if you look at this pic, the little nub was stuck in the area just between the small protrusion of thin metal with the hole in it and the black thing the key goes into. its really hard to tell with my cell phone pic, but theres a little square hole right there and thats where this little orange piece of broke plastic was hanging out.
i inspected the entire assembly to see where the orange piece of plastic came from, but it wasnt obvious. so im guessing it was part of a piece you cant see on the inside. im having a hard time believing that little piece of plastic was what was keeping my ignition from turning, but i have no other theories. it seems like if that little piece of plastic was the culprit that i would have been able to jiggle it past it. especially with how sloppy that little bit of plastic was in the area it was stuck. the ignition was solid when it was stuck. it didnt budge at all. who knows, but everything is still working good...for now.
