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
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.

What type of vehcile? most likely in some models the passlock sensor has failed.
Check the ignition system on ur corvette. i think the fault lies there.
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: replaced multiswitch in 2000 chevy s10 blazer and now the car won
at the base of the steering column there a orange and white wires these two wires come from the ing switch, you will see the connector that they go to disconnect that take a ohm meter, take the leads one lead to one wire the other lead to the other there should be res, if there is not, try a different setting . take your ing key on the the key you will see a chip take two leads from your meter and either side of the chip place the leads you will see a res reading, you should see the same at the orange and white wires . if you do not replace the ing switch the switch will come with these wires. replacing the switch takes a couple specail tools good luck and let me know how it gose
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.

Here is a detailed write-up on how to bypass the entire VATS security system yourself.
http://newrockies.ca/vatsbypass
This is what saved my car and my money (that I didn't have!).
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.
