like I said mine was acting up so Sat. I took my truck and bought the cheapest of the three offered at AutoZone. When I drove home and got in the stang it took me 30 minuets of constant trying, moving the wheel while trying to turn the key, moving the release knob, pulling the key out a 1/64 to get the key turned to "run". Are you trying like that and just being patient and playing with it to get it to turn?....finally got it to turn after a half hour of trying. Then I used a 1/8 drill bit to depress and pulled the old cylinder out
