Here is a great write-up on the subject. This will get rid of the entire Passkey system and the car will start like new. It was the only thing that saved my 94 Park Avenue: http://newrockies.com/vatsbypass . I had the exact same situation.

DOES THE PASS KEY II THEFT SYSTEM NEEDS TO BE DISENGAGED THROUGH THE RADIO THEFT 4 CODE SYSTEM TO RESTORE THE FUEL SYSTEM IN 1995 OLDSMOBIL88 LSS


The Passkey anti theft system and the radio theft deterrent system are completely separate systems, so the answer is no the radio code does nothing to the Passkey. Passkey is a passive system, that is to say it disarms itself and arms itself just by inserting or removing the key from the ignition and locking the door of the car either with the key or the remote. If the Passkey is the source of any problem and is not working correctly then the Security light should be flashing in the dash to indicate a problem. The most common issue with the Passkey 1 and 2 is that the reader located in the ignition switch lock cylinder goes bad, this locks out the fuel pump and the engine will not start. The system can be bypassed but it is not easy.

How to reset the auto thief system?


Hello: There is no any reset on the GM theft deterrent system. If the security light is on or the security light is blinking it means there is a malfunction and you have to have it diagnosed with a scanner (GM) and repair it. (what good would a theft system do if you could reset/by-pass it?????)

Passkey light flashing


Hello: Does the truck start? If it does it means there is a problem with pass-lock and one of these days it may quit starting. Best to find out what code is setting, not all gernic scanners can read it. GM scanner will.

The dashboard security light blinks in my 98 camaro


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

My 1999 tahoe has a security problem. The light comes on and goes off it will start.If the light flashes it fails to start. can you help


The pass lock is beginning to fail.You can try reporogramming it following this procedure. If it still continues to happen the pass lock/ignition tumbler may need replaced.
PASSKEY LOCKOUT RESET ALL GM CARS 1999 AND UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key

Won't start, radio locked, security light flashing and check engine. Disconnected positive battery and connected started. While driving radio locked up again amp dropped out and air quit stopped shut off...


If your vehicle has the GM Passkey system, it is possible the security lockout has been engaged. The way to reset the Passkey system is as follows.
1.Turn the key to the ignition "on" position (but do not start the engine) and leave it in the on position for 10 minutes. After the ten minutes has passed, turn the key to the off position.
2. repeat the above step 2 more times. This will take about 30 minutes.
3.Do not attempt to start the vehicle or use any accessories while performing this reset procedure.

I hope this helps.

Passkey light in the dash flashes and the car wont start on a 95 buick roadmaster


pull the fuse from the fuse panel on the left side of the dash. It can be accesed by opening the drivers door and removing the panel that is the left end of the dash. Pulling and reinserting the fuse will usually solve this problem. The other issue could be in the key itself. The pass key is simply a resistor built into your GM key.
