OK, the Security light comes on while driving....does anything happen when the light comes on? I don't think the car will die if the light comes on while driving......If you shut it off, and the light is still on, the car won't start.....

First, have all codes read......every module....

9 out of 10 times, the problem is the lock cylinder, more than anything else...
