Are you using the right key? Weird that its locked up on you.. Try holding pressure on the key in the same way you would start the car and wiggle the steering wheel from left to right...
the ignition is faulty i believe, but i cant get warrenty on it because ill have to cut the housing to get it out. not worth it. ill just try drill through the pin to remove the housing.
