I have a 2001 Chevy Malibu. The anti-theft light keeps coming on. Some times it just comes on and nothing happens, then other times when I turn the car off and try to start it back it will not start. Now after the car want start I have to reset the anti-theft. Having to do this about 2 to 3 times a week now. I have no clue where to start looking to solve this so that I don't have to keep resetting it all the time.
