Battery any good? Battery contacts? Solenoid? Ignition switch good?
Sec life ?????? SECURITY LIGHT ? anti-theft system problem .
The Pass-Key II® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
How to bypass GM VATS system GM no crank no star
SOURCE: 1999 Buick regal Security light on. Won't start.
I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.
SOURCE: 2000 buick regal lse 3.8 wont start or turn over
several things to check out:
get it started and go have the battery, alternator, and voltage regulator tested. No charge at most parts stores.
IF they all test ok then you will need to remove the starter and have it tested. The solenoid could be bad. Was it wet outside the day it wouldnt start? if so then oisture is probably getting into the solenoid.
