A few weeks ago, I was running around town and went to shut off the ignition. The key wouldn't come out of the ignition. I moved in and out of gears just to see if it wouldn't getting into park correctly and this didn't fix the problem. I actually ended up driving the car home. I left the car sit for a few hours and went to try it again. The key removed immediately. A few days later, the same problem happened and I have been unable to get the key out. Everyone I talked to said it was the ignition cylinder, so I replaced this with a part I purchased from my local dealer. After removing the old part, the key removed from the ignition. I installed the new part and the same problem occurred. I am at a loss on what the problem could me. I am by no means an expert at repairing cars, so I was hoping I could find some help here. Thanks for any ideas anyone can give me.
