If the ignition key does not turn and/or cannot be removed, a new lock cylinder may be needed. A worn key can also cause similar problems.Google+

Key goes in, but won't turn so I cannot start the car. First time this has happened. I'm going to be late for work today, no doubt because of this Chrysler POS!!!

I have had a problem with the cylinder. When I turn the key right before the engine starts, all is well. But, when the engine starts, the air-bag light comes on the dash, the air does not work the electric windows do not function and the turn indicator does not engage!!!!!!
I have to jimmy the key back-and-forth until everything works. I was told it would cost over $450.00 to fix. So I just jimmy. Then the interior door handle broke and they do not make it any more-not in stock! Then the arm rest fell off from the center console. I know they do not make this model anymore. THEY JUST LEAVE US ALL STUCK WITH THE HEADACHES!!!

i had a similar problem with my 1997 Chrysler concord, one day i just couldn't turn it to get the key out. turns out the shifter lever has to be pushed forward slightly while in park for this to happen. it was like it was sticky or too tight and needed a good push to slide forward. once i discovered this, the key came right out.

try the micro switch on the shifter when it is in park----faulty or misaligned
