The security light will flash and disable the fuel injectors preventing the car from starting, if it thinks that it is being stolen. its easy to fix. set the parking brake to turn off the automatic headlights. next turn the key to the on position and wait ten minutes. the security light should stop flashing. then turn the key off and this will reset the security system. it should start immediatly afterwards.

SOURCE: 1997 Pontiac Grand Am red security light is on and

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.

SOURCE: 2004 pontiac Grand Am with security passlock starting problems

Unfortunately you are correct, this
vehicle has the PASSLOCK II key
based engine disabling system, and currently it
is engaged. The sensor does not recognize &
retain the passlock reader chip in your ignition
switch any longer.

A bypass is required to circumvent.
If left unchecked, it will lock down the fuel injector
rail (as it has now), and you will need to
tow it in to GM for evaluation, and resetting.
Eventuall, the 10 minute over ride will cease to
work and you will finally be forced to visit
a Pontiac/GM dealer.

But, if you want to just remove this system
from the equation entirelly,
I suggest the PLJX bypass kit to get around
this issue.

This Passlock Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.

The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the passlock system.

That is it's designed purpose.

However, in your case, this input wire on the PLJX module,
instead of going to a momentary ground pulse from
an alarm/remote starter,
would go to a constant chassis ground, through
the bypass module, grounding out the PASSLOCK.
The PASSLOCK would then always be bypassed as long
as that wire is chassis grounded.

I can not speak about a damaged passlock system,
like if a thief has destroyed it, because I do not
get into this part of GM'S security application.
Coincidence to installing
after market remote starters, this does work on bypassing
passlock in most all GM vehicles,
including your year GM vehicle as well.

Also, this is a self learning, resistor sensing
and adjusting module. Once the VATS wires have been tapped,
you would press the program button to learn,
and it does. The car should then allow start
with any hardware store key.

This happened to me as well - always at the most inopportune time. When you get this, turn the ignition off, then turn to on (do not start). Let it sit there for about 10 minutes. Once the security light quits blinking you are good to go.

Not starting


It was the security Passlock system on my car as well. I did't notice that the security light had come on the first time. Look up Passlock in the owners manual.
  1. You can reset it yourself for free by turning the key to accessory position
  2. Leave for ten minutes on accessory mode.
  3. Turn car off completely
  4. Try to restart.
This fixed my problem on my own after I paid to have it fixed and it happened again the next day.
