2002 Chevy Malibu will not start Theft deterrent light stays on and will not reset by owners manual instructions?
From everything I have read about this, if putting the jey in the 'ACC' mode for 10-15 minutes doesn't reset the system you will most likely have to have the key cylinder replaced by the dealer. The security Passkey system will probably have to be replaced or bypassed.
It will be listed in the back of your owners manual. If you lost the manual and your car is faily new, GM has started to keep a record of all manuals on their website. You can just do a quick Google search for Chevy Malibu owners manual, and the it will take you too the gm's page where you will have actually select the year and model again.
