SOURCE: my 2000 chevy express won't

this is a 30 minute procedure. make sure you have a battery charger on it. to begin, insert the key into igniton, attempt to crank the engine, do not start. leave key in the on position. if the system is working properly after 10 minutes the security light should go out. turn key off for 5 seconds and then back on and attempt to crank engine again, do not start, after 10 minutes the security light should go out. repeat the above steps a third time. after the third time. turn key off and then start the van, if system is working properly it will learn the passlock again and car will start. if this does not work, try it once more making sure you followed these steps. any variation from these steps will stop the learn process. if it stiil does not work, then you either have a bad passlock module or sensor.

Why won't 2002 Chevy express van with Sidewinder security system headlights shut off when headlight switch and key is off?


Either the headlight relay is stuck on, or the security system's headlight control is shorted and keeping the headlight relay on. Find the headlight relay (probably in a fuse and relay box under the hood), remove it and check the contacts with an ohmmeter. They should read open in a good relay, but will read little or no resistance if the contacts have welded together ( a possible result of rapid on-off cycling).

You need to get the codes from the theft deterrent module.Usually a B2960.This will help in the diagnosis of the problem.Hope this helps.Good luck.

2001 chevy impala security light keeps coming on


This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.

it may be the security system but i don't know how to bypass it. most security systems only prevent the original radio from being played if stolen from your car. but wouldn't affect a new radio. you may have to call a local dealer and ask them. the only other thing i can think of is when installing the new radio, you unhooked a wire or cut a wrong wire. good luck
