How do you disable the theft system 2000 Pontiac Sunfire?

Answer 1

I have a 2005 sunfire and i realize that the theft systems might be different on different year models of the car-

i had trouble with my theft system going off randomly- the car would crank but not start and the "theft system" light would flash. I called several dealerships and even tried calling a GM hotline and they all told me the same thing- the theft system cannot be disabled, like it or not it is part of the car and if it is defective it needs to be replaced.

there is, however, a relearn procedure you can use to get the car to start without towing it to a shop.

1) try to start the car (it won't start and the theft system light will flash)

2) leave the key in and resting in the "on" position (the position it's in after you crank and release- turns on the radio, dash lights etc.). the theft system light will continue to flash for about 10 min and then it will stop flashing and stay on.

3) turn the key to "off" and leave it there for another minute or two.

4) try starting it again. if it does not start now, it should after repeating the above two or three times
