So went to unlock my car and I had this happen

 

The outer have of the cylinder came out if I stick that half back in and use the key it still works but it won't stay in what attaches this and how do I fix it I really don't wanna put a used cylinder in and have 2 separate keys

 

I have the opposite problem. I have a junk yard door and can't get my old cylinder out.

There's some sort of clip-style cover on the back, but I can't figure out how to get the damn thing off.

Sorry I can't help, but I figured I'd bump your thread for you and hopefully we'll both get our answers.

 

Right cause I have a spare door in the same color but obviously a different key that I don't have and I don't want 2 separate keys that's just a pain

 

What year is it? Had that happen on my 96. Since my remote fob worked, I just blued the lock back in place and relied on the passenger side lock as my backup. At 99.5 they did away with the pass side lock though.

 

It's 96 what kinda glue worked best

 

Pretty sure I just used an epoxy...I usually have JB Weld around. Keep the disk brake cleaner handy in case you get some smeared around. That stuff eats epoxy pretty good.
