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.
----- http://vats.likeabigdog.com/


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.
----- http://newrockies.ca?ap_id=judd0081
----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

You'll have to change out the steering column or actually the ignition key cylinder but keep the door lock key...after you change the key cylinder lock the doors with the key then unlock the doors with the key and it should start and run fine

SOURCE: security light flashes

from what i have read, it is design to cut the gas supply so no one can still your car. Mine car wouldn't crank at all with the light blinking. turn the key to the on position and wait 10 minutes. turn it off and try to crank it. it has worked every time on mine. I have also read to cut the LITTLE yellow wire that runs from ignition,but i don't feel comfortable cutting wires even though you can always reattch the wire.

SOURCE: my security light comes on and i can't start my car

your car security system can not be disable but it can be bypass

but firts on these models it is the pass key the problem

on your key to strt the car you have a little round black thing with a little metal contact this is a resistance that is in your key when you put it in the hole to start your car it mesure the ressistance
and the you can start your car

the usual problem with this system is that in the ignition key lock cylinder there are two wire
and usualy one of the two wire just cut so i would remouve the stearing wheel and get that wire fix

hope that will help you !!!

the way to bypass the system is easy but you need to realy know what you will be doing

first you mesure the ressistance in the key in (ohm) and second get a ressistance the same value from any places that sells electronics

after you will find in your car the passkey decoder module (behind right side of i/p)
the two wires that come out of the box (B7 ppl/wht and B8 wht/blk)
cut these two wires and weld the ressistance in bettwen
this way you won t have to take your stearing appart
and your system will be bypass for ever

great day to you

The process for the passlock relearn is correct. If by chance the relearn does not work, you may have a fail component in the system. Go to this link for options to fix this yourself.

1 Answer

The car sat up awhile. The battery died. We replaced the battery but the car still won't start. Everything comes on. The starter was tested and it was fine. What is the problem?


THERE ARE MANY POSSIBLE CONDITIONS THAT COULD PREVENT YOURCAR FROM STARTING. 1. NUTERAL SAFETY SWITCH IF THE CAR HAS AN AUTOMATICTRANSMISSION. 2. CLUTCH POSITION SWITCH IF THE CAR HAS A MANUAL TRANSMISSION.3. BRAKE PEDAL SWITCH. MANY NEWER VEHICLES HAVE A SWITCH ON THE BRAKE PEDAL ANDIF THE PEDAL IS NOT DEPRESSED WHILE TRYING TO START THE CAR, THE CAR WON'TSTART. ANOTHER POSSIBLILITY IS THE SECURITY SYSTEM. DOES THE CAR HAVE ASECURITY CHIP IN THE KEY? THESE ARE SOME OF THE MOST COMMON REASONS THAT A CARWON'T START FOR NO APPARENT REASON. HOPE THIS HELPS.

When I try to start car, it won't start and security light blinks. I'v e had to ignition switches put on before and I had a new key made. Car still won,t start.


If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.

SL2 ? 2000 starting problem


I had the same problem at one time and what the problem was is a short or an exposed wire connected to the starter which causes the voltage to fluctuate which in turn activates a security feature that stops the flow of fuel to the injectors. The car actually senses the possibility of a spark which could possibly ignite the fuel and be a fire hazard. If you turn the ignition on and off repeatedly after a certain amount of time the car will start and run fine. It is a very intermittent problem.
