2005 Cobalt,Shut off the car & the key wont come out .seems to be activated thru the brake pedal. I know about the override switch under the steering column. I know that 1000's of GM cars have this issue.any help on fixing this would be appreciated. I have 2 Cobalts and they both do it periodically. Thanks, JC

CHEVROLET/PONTIAC: SEE DOCUMENT SEARCH BUTTON FOR OWNER LETTER. A BINDING CONDITION HAS OCCUR BETWEEN THE HOUSING AND IGNITION LOCK CYLINDER WHICH MAKES THE IGNITION KEY DIFFICULT TO TURN OR REMOVE FROM IGNITION.
There is a service bulletin on this. You should be able to bring it to the dealer and get it fixed at no charge (though they will charge you the cost of making a new key ~30$).
My father had the same problem. I turned the wheel back in forth as best I could (considering it was locked) and turned and wiggled the key. Eventually it came loose.
They have junk lock cylinders. There's a new style that may or may not work better, depending how good the guy who coded it is. you don't usually need a new key
my equinox did this and they replaced the lock cylinder and the key i was under warrenty so they never charged me for the key

My ZR2 did this also twice under warranty.
Finally the replaced it with a diff style lock cyl and a new key.
Good luck with it.
My car was made with wrenches, Not chopsticks.
