92 Park Avenue won't start & security light flashes

My 1992 Buick Park Avenue(V6-3800/198,000miles on engine) won't start. When I turn ignition; there is no sound only security light flashes on dash. It has been wrecked on the front driver's door. Every since then; car would start sometimes but most times security light flashes. Now it won't start at all. Can anyone please help me with this.

The likely reason is that the VATS module is not reading the ignition key resistor pellet.

Perhaps this will be of some use:
