theft warning display

i was driving and the theft warning car may not restart come up on the display and my sevilles engine stalled and wouldn't restart. has anyone had this happen and is there a way to fix it without taking it to the caddy dealer. thanks

i know that other GM products had problems with their security keys. i would imagine that if it just popped up, it would have to be an electrical issue, such as a bad sensor or key, or something along those lines.

i had this happen to me and i got it fixed for about $200.. its stupod they need to replace the ignition switch and make u a new key with sensor.. u dont have to do it at the dealer though.. the dealer would do it for around $400
