So I am new to this. I don't own the grand prix, my boyfriend does. What happened was that I had plugged in the seat cover heater into the outlet and made the mistake of leaving it plugged in. So obviously the battery has been drained. But when he went to put his key in the ignition it was jammed. It took us awhile to get the key out (nothing broke during the process). We tried boosting the car and were able to get basic power (lights and power locks) but the steering coloum is locked, and it seems that the ignition is as well. Like, we cannot turn the key in the ignition at all. We aren't sure where to begin or what to do. We are currently charging the battery.
