key chime sounds if the little tab is grounded where the key contacts it. The theft light is supposed to blink when the system is armed to let you know it is armed. That's normal.
What do you mean by auto door locks won't unlock? The remote doesn't work? the door lock/unlock button on the door trim panel? Do they lock ok? Or, just unlock doesn't work?

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with New Generation STAR (NGS) Tester.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.
