Thank goodness for this site. After having fixed a number of things on my car and driving it more than usual the last few weeks, I noted the other day that I couldn't get it started-- that the key was locked in there. After some wiggling it worked fine and since then fine. We were actually out in the country, getting stuck out there would have been ugly. I bet the tumbler is going bad based on this and other threads and so I'll change it immediately. I never would have thought about that without this site. I'm going to use an aftermarket one since I hate dealing with the dealerships on anything I don't have to, will just have 2 different keys, doesn't bother me.
