QUESTION: we just got a prostart 3 in 1 but before i get started is it absolutely necessary to get a bypass module?  or is there a way to wire past it?...lol i would really appreciate anything else i might need to know before i get started too...thank you very much

ANSWER: Depends on the make, model & year of the GM vehicle.

QUESTION: sorry it's a 2000 Pontiac Grand Am  4Dr

ANSWER: Yep, this
vehicle has a the PASSLOCK II key
based engine disabling system, and currently it
is engaged. The ignition does not recognize
the chip in your key 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.

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.
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.

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.

QUESTION: thank you so very much you don't know how helpful that was...but just one other question in the whole process of this thing...if i was to do this thing, would i need a resister of some sort to get the door lock/unlock funtion to work??? is says that sytem is multiplex whatever that means...thank you again ur so great...i love people that know what they're doing  :)

Answer
Ah, this simply means that they are using 1 wire
to do locak and unlock in this care, and to
differenciate between the two. GM's way of
saving some $$$, but we figured it out.

The Lock requires a negative trigger, directly and unlock
requires a negative trigger through a 1,500 ohm resistor. You will require relays to get this done correctly.
See www.relayhelp.com at "single wire negative door locks" to get that part done right too.

The Radio shack has um,
& you must close doors to lock with a single pulse.

And that's that.
