I busted the key off in mine...went to a junkyard and popped an ignition switch and key out of one and replaced it. Super easy to pop in and out. As far as PATS goes, my car had an aftermarket alarm installed on it when I got it. I suspect that PATS has been somehow bypassed, which would explain how I was able to just swap lock cylinders like that. I still ahve to address this problem, as I now have no doors keys (the key that broke off was the only key I had). Should I reinstall the original lock cylinder and have a key made or just have the key made for the doors? I would have for this alarm to go on the fritz and not be able to start the car.....lol!
