You likely have a bad ignition lock cylinder. You will have to replace it or bypass the security system.

GM Passkey Security Systems: What You NEED To Know. Written by NEWROCKIES Inc., February 7, 2014, GM Passkey, GM VATS
Back in 1986 the GM Passkey security systems, also known as immobilizers, were introduced. In doing so, an expensive was implanted in each and every one of the affected vehicles. Given the impact of the GM Passkey systems in the years since they were introduced, it's not really clear whether the intention was really to provide additional security, or to generate a new revenue stream.

GM PASSKey goes by many names

Over the years, GM has come up with a number of catchy names for these systems:
  • Vehicle Anti-Theft System (VATS)
  • Personal Anti-theft Security System (PASSkey). To be precise, GM PASSkey I, PASSkey II, and - count them - PASSkey III.
  • PASSlock. After all, what good is a key without a lock?

The disabling effect of GM PASSkey Systems

In spite of the efforts to make the systems, generally known in the industry as PASSkey Systems, sound effective and ever more advanced, they are really all pretty much the same.
It doesn't really matter if the vehicle's PASSkey System is controlled by a resistor in the key, by the Theft Deterrent Module (TDM), or by the Body Control Module (BDM).
One of the key attributes that all the GM PASSkey Security Systems share is that they systematically end up immobilizing cars, alright, making it impossible for their owners to start them!
Yes, the many versions may all look different, but they are all based on the same simple idea - so simple, in fact, that you could argue it's not a suitable foundation for building a true security system.
Most importantly, they all end up immobilizing the host vehicle permanently and often before it is even 7 years old. In all cases, your friendly dealer will ask at least $1,000 to fix the problem - which will invariably strike again after some more time.
But wait a minute... what's a car dealership's core business? It's not repairing obscure, crippling vehicle problems, at a reasonable price. It's selling you a new vehicle, as often as humanly possible.
So even if your dealership were inclined to help you repair or replace the GM PASSkey Security System... well, what a coincidence, many of all those versions introduced over the years have been completely discontinued.
In the meantime, your car still won't start, and that won't change unless you have a way to disable or bypass the GM PASSkey System, and so far... you don't. Nor do you have time to figure it out. And your time is money. Money on top of the taxpayer-funded bailout of GM in both the USA and Canada.
So what do you do end up doing? Maybe you junk the lame Chevy. Then you take out yet another loan to buy another one. That's a perfectly happy ending to this story.... for the dealer, for GM, and for the bank.

Don't get me wrong! What I hate is Passkey, not GM!

Look, don't get me wrong. I love GM cars. Most of all, I love Buicks! I love the sound of the engine, the understated attitude, the size.... In fact, I love them so much, that I own two of them! You can even read about
how I saved my '95 Buick LeSabre from the PASSkey trap. And I was recently lucky enough to get my hands on a rich gold 1970 Buick Electra in mint condition, no GM PASSkey Security System in that one, thank you very much!

An ounce of prevention....

Is worth a ton of cure. You remember that saying.
Remove the GM PASSkey "Security" System before it gets a chance to take out your vehicle. Seriously! Even (or especially) if it's still starting every time, just do a full bypass of the PASSkey System with the NEWROCKIES Inc PRO Module and save yourself a great deal of money, time, and aggravation.
And if your vehicle is having trouble starting - trouble that cannot be traced to the usual easy suspects, like the battery or starter motor, get it

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.

Car shut down and security light is blinking


Try doing a Passkey security system reset (procedure below), if that is not successful then you will need the dealer to scan the VATS module with controls the security system.

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.

Se activa security en el tablero


A special security indicator light provides information about system operation and self diagnostics.

The security indicator is controlled directly by the PASSkey(R) decoder module. If there is a PASSkey(R) failure this indicator will be grounded by the PASSkey(R) decoder module with the ignition in RUN, BULB TEST, or START. When the ignition switch is first placed in RUN, BULB TEST, or START the indicator lights for about 2 seconds as a bulb check.

Some vehicles may show additional messages if equipped with Driver Information Center or Body control.
