Something went wrong while attempting to change my low beam headlight on driver side

[Kellibean83]

I was trying to change my low beam headlight on driver side and after I got the cover/cap off that covers the light I couldn't get a hold of the bulb to remove it. So I thought I should turn my wheel the opposite way so I could see it better.. fyi I didn't remove the fender ..anyway my car started just fine and I turned my wheel the opposite way..still no luck.. well now my car won't turn on. Key won't turn. Steering wheel won't unlock, can't push brake pedal in at all.. but a few times as I was sitting in the car with key in the ignition it actually tried starting by itself. I was not touching the key or anything.. this happened a few times.. what did I mess up? Did I loosen a wire or something that I shouldn't have? As far as I know I never pulled any wires out or moved them. Someone please help
