Today, I turned off the car (seems to turn all the way to the "off" position fine), and the key will not budge out of the ignition lock. I can still turn the car on, drive, etc. Steering wheel is not locked.

I have never had any hint of this problem before, and always drive using the same key. Does anyone know what the problem could be? I am supposed to have the car to the body shop in the morning, so any advice on how to rectify this would be very muhc appreciated.
