Car Alarms: Alarm or cars fault, gm passlock, passlock bypass


Question
I recently removed my battery to work on something really quick.  When I hooked it back up, everything seemed normal (alarm started going off as it usually does).  When I put the key into the ignition and turn to the 'on' position, everything looks fine.  All gauges and dash lights operate as normal.  Then when I switch the key to 'start', I get nothing.  I can hear the ignition relay in the fuse box click when I turn it.  Also, I noticed that the dome light is not on.  Would this be my alarm, or possibly my car going into the GM Passlock problem?  Also, is there a way to remove just the ignition cutoff for the car so that it is no longer affected by the alarm?  I looked up in behind the dash, and didnt want to just start cutting wires.  Another problem that I had was that the locks (remote and buttons on the doors) no longer work.  I brought this problem in to the installer, and they said that it was GM's fault somehow.

:>( Bad news I am afraid.
Somewhere along the way, the passlock system
was reset. Possibly when or, if the battery
was removed. This is a problem.

This vehicle has a the PASSLOCK II key
based engine disabling system.

You can attempt to put the key in the ignition,
turn it on to just before cranking and then leaving
it that way for 10 mins. After that,
some PASSLOCK systems will re learn the code
and allow for starting. But if not, the system
will either need to be seen by GM or, a bypass module
is required to circumvent.

If left unchecked though, it will continue to lock down
the fuel injector rail, and you will need to tow
it in to GM for evaluation, and resetting anyway.

Bothersome, but can be fixed.

I suggest the PLJX bypass kit to get around
this issue. www.PASSLOCK2.com

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.

The catch here is that the car engine
MUST start to program this module or it
won't work.

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 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.

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