key won't turn
 

ok could this be a lock cylinder . put the key in to start and it won't turn. i wiggle the key and it turn on. i check this again this morning and it started right up. my car is a 95e320. is this common any help would be helpful thanks

Yeah, sometimes the wheel position will prevent the key from turning, just play with the wheel with the key in and you will find the position that lets you turn it on.

move your wheel left and right while your turning the key.... you'll get it ;)

make sure your car is all the way in park as well
but it's most likely the steering wheel position

If above fails....... the tumblers are jammed and a little force is needed to dislodge them, try hitting the key with a hammer into the lock if that fails just force the key clockwise with pliers, not to the point where the key is going to break but enough pressure to dislodge the stuck pin. :naughty:

i second that motion.

The steering wheel and shifter position are common things your probly would have checked before posting a thread about this.

I had the same problem when I first got the car. It would be fine sometimes, and other times it would be impossible to get started. I had read up on bump-keys and how they work so i gave the mallet trick a try. Sure enough a little tap into the ignition fixed the problem. I sprayed a little slick 50 lubricant in and it hasnt stuck in almost 2 years.

I also want to reassure you that I wouldent recommend something I haven't tried myself, so I second Rivcal4life. I have tried this while "stuck at college" and the above fixed my problem. I've been good for about 6 months now with no stickage. :zoom:

thanks guys

Repair BEFORE getting stranded.
 

Mine did it too. I got a new ignition lock from Mercedes for $85. NO TOW for me.

It was simple to replace it (search this forum for instructions), and when it came out, I found several pieces of the old one jammed up in there.
