By buying a ford, (joke) seriously the only thing you can do is have your dealer reset the computer for you, it thinks you stole it and needs resetting, To remove it you have to remove the entire EMS and BCM, basic all your computers from the car and that is just not reasonable

Check the battery cables, both positive and negative. Not just on the battery end, but at the starter, and the engine block. The cable could have a bad spot along its length that may or may not be visible. The best troubleshooting step is to replace them.

1999 chevy malibu won't start

if your theft light is on you must disable the security system you have to use your remote to unlock the vechicle which will turn off the security system if your remote is not working you can unlock the rear hatch with the key and it will shut off the alarm if these things do not work you must have the security system read by a dealer to determin if the bcm is the cause the only other way to bypass it is to replace bith the bcm and the pcm with modules out of a vechicle without theft
