What does it mean when the red "security light comes on while I am driving?


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Security light comes on when first started for the day, use to be random but more frequent now, i usually shut the car down and restart and the security light will go out. if i leave the security light on...


It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shuting down while running, im sorry i have no quick fix...

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page......... They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks.

----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

Put new alternator and battery in 1995 Buick Lesabre with key pass will turn over and run afew seconds but wont stay running


actually a pretty easy fix. The pass key computer lost its programming. Put the key in and leave it on with the security light flashing. Just turn off all your accessories and make sure battery is pretty good charge. Anyway after you leave the key on for ten minutes the security light will come on steady so turn key off and right back on and start car. If security light still starts blinking and car stalls then do it again. It will usually work the first time but can take a few times to get it right.

2004 Alero. Car turns over, but won't start. Security light blinks.


Hey jonce17....I had the same problem, and my Alero sat in my driveway for 2 days. I looked online for the solution, and I found out how to bypass the security. After it won't start and the security light is blinking, turn the ignition to the on position. Leave it there till the security light stops blinking and stays on (usually takes 9 to 10 minutes). Then turn ignition to off position and start it like normal. This happens to me about once every couple of months. Hope this helps....

Need to have a code scanner hooked up to it to find out why the light comes on, that will identify the problem, might be one of the four wheel speed sensors.
