The chip in the key is not a chip, it is a piece of resistive wire, the key reader See's the resistance of the key is correct and allows the car to start. The common cause of the problem you have is the reader in the ignition lock cylinder. You can't buy that part anymore so you must bypass it, this of course will disable the security system (called the VATS system). Here is how you bypass it, go here to read about the procedure.

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

Security light is on and the car wont start


Try removing the negative battery cable and charging the battery full. Then hook it back up and wait 10 minutes or so. If this fails try having the key checked as these keys have a chip in them and the chip can stop working. Most high end Key shops can make you a new Key if that is the problem.

1999 PONTIAC BONNEVILLE SE wont start security lights come on windows wont work, had it happen once b4 thought was out of gas put gas in still same waited an hour started right up, never had prob again...


Had the same problem. Took it to local guy and he put it on the computer and found the wire running underneath the driver side floor mat had gone bad. Had to do with the security shut-off, which this wire affected. Replaced that wire, and the car has been running great ever since - happened 19 months ago.

The security system (VATS/PassKey) is having problems, it's typical on those cars. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

I need to get the schematics to the ingnition wiring . I own a96' pontiac bonneville and everytime I start it ,or try to,the engine starts only then to immediately shut off.I have a friend who works on...


Sounds like the security system is engaged. If the security light is flashing with the key on, leave the key on till it stops flashing (about 10 or 15 minutes) then once it glows steady try and start it. The chip on those is in the tumbler assembly and you can change that if necessary then re-set it. You don't need a schematic for that and it is a classic symptom. It's easy to try and wont cost you anything if it just needs a re-set.
