Question
The security light on my camaro used to come on, and when it would, the car wouldn't start until it went off, then my dad changed the battery, which reset the memory, and now the car wont start at all, and the security light blinks. I have a viper alarm in it, I've taken it to two places, one place told me, the viper alarm was trash, and that i needed to replace it, so i took it to another alarm place, and they said the viper alarm was fine and it was the starter.

So the tow truck guy told me to test to starter, and if it spun, then it wasn't the starter, and that its the factory alarm.

I've had so many opinions and spent so much money. I'm about to get a diagnostic test on it today, for $80, but before that I need to see if its just a simple problem i can fix before i go and spend more money! Plllease help me!

Answer
This vehicle has the GM Passlock II immobilzer
anti-theft system. A bypass is required to
circumvent.

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 the 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.
But as a happy coincidence to installing
after market remote starters, this does work on bypassing
passlock in most all GM vehicles we've run into,
including your year GM vehilce 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.

Hopefully, it will on yours as well.

You might want a car alarm installer to do this
for you, the fair rate being around 50. to 75.
for labor.
