Weird... I drove the car earlier today without any problem, and then when trying to start it later in the day the key wouldn't turn past the first position. I've tried all the keys that I have (two regular and one valet), with the same result, so I know that it's not a problem with the key. Obviously the car won't start, and I can't shift out of park without the ignition turning to the second position. The owner's manual provides no help.
Has anyone experienced this before or have any idea what might be the problem?
