my car turns on then stalls will not stay on after 2 trys the engine will not start

on my PT Cruser i had to get keys made from the dealer because the keys have a chip in them. Did you get keys made elsewhere? If so that could be your problem

Believe it or not, the problem is your alarm system. Tell the mechanic to unplug it, and to reset/re-program the system. Once that is done, the problem is solved. I had an amazing mechanic who always did an amazing job of finding what the problem was.
