Flashing security light??

When i get in and start my car the security light flashes for about twenty min or so and then shuts off. It has been this way since I got the car. Any ideas on what is causeing it?? :th_scratchhead:
 


Yup. It turns on every time that the car is started. stays for about the 15 to 20 min. then goes off. I was told that the ignition switch is bad, but it has never failed or shown any signs of it. I dont have a manual for the car is there any thing in there about setting things up??
 
whoever u bought the car from stole it...thats the onstar trying to pinpoint location bwahahahaha jk
 
the stupid passlock sensor is probably dieing, bypass it as it is useless to any real thief (they know the bypass tricks and it only takes a few seconds)
 
Put the key in, turn the ignition to RUN and wait 30 minutes. That will do a passive re-learn of the transponder in the key head. Try that...
 


I know that it should really not be made public, but I would really like to know how to disable the passlock? Befor its to late and I am sitting on the side of the road at 4am on my way to work. Thanks to everyone for far for the info:th_thumbsup-wink:
 
There are several GM anti-theft modules... VATS/Passkey1/Passkey2/Passkey3/Passlock/Passlock2. Need to know EXACTLY what you have. I just did a permanent bypass on a VATS/PK1 system this weekend on a 96 Buick...
 
If I get this bypassed will I be able to install a remote start without having to use the security stuff. More or less like an old lumina or somthing obd1 with no security??? That and I still need to know how to disable it!!!:th_scratchhead:
 


Try this to re-learn key and system--Turn ign to run position (don't start) wait till security light goes off--turn ign off and back on again (security light should be flashing) wait till light goes off again--turn off and back on (light will be flashing) when light goes off this time start the car (don't turn off before starting) This should take care of light-each procedure will take 15-30 minutes-be patient
 
my buddies cars security light is flashing to but when he turns the key to the off position the car still runs and then he has to unplug the alternator for the cr to stop running. has any one ever ran into this problem?
