I am trying the sticky key fix but my key apparently doesn't turn to the 1st position in order to get the tumblers out - the key turns clockwise but maybe not all the way to the first position??? What can I do? After having the car towed apparently due to a cam shaft position sensor failure, the key would no longer turn. It was towed on a flatbed so not sure why that would impact key except that it was probably hooked up by the front axle.
