Have you tried to Insert the ignition key into the driver door lock. Turn the key counterclockwise. Turn the key clockwise to lock the door. Turn the key counterclockwise to unlock the door again. This will shut the alarm off and reset the system. That doesn't work the radio has to match the pcm if it doesn't the dealer should program it to work with the new pcm cost me 50bucks to have done.
