Passlock System

PK3 vehicles like most of the newer Caddy's, and brand new GM vehicles do have a "chip" in the head of the key. You don't see it but there is one.

If you do what I did in my previous post you'll eliminate the magnets completely. Once you do it and it starts, it should be fine every time.

what ?

i was always told that passkey is with resistor in the key and passlock is with resistor in the cylinder only

what gives ?

I think you have the VATS system mixed up with these newer systems. VATS had that chip you could actually see in the metal shaft of the key. The new PK3 keys use a chip that's embedded into the black head of the key.

Doing some research on my exact same problem I found this thread, but this post from ponchnutty really worried me. I have a Malibu LS 2001 and it has been having problems to start ... "Theft System" light on dash. Nevertheless, it has also ocurred to me like 6 times that the car is already running, I'm driving and suddenly it just dies. I put in Neutral and the car starts just fine! ... do you think it may be a problem with the auto-tranny? I am wondering if the computer keeps a log of all error messages ... just to make sure if it's passlock or other system the one with the problem.

Thanks for any comments on this.

Yes, any and all error codes will be stored but again, if the car just dies as you drive, it isn't a security issue. My guess would be a loose wire or connection somewhere. It could even be as easy as a loose/dirty battery cable. GM did have major issues with battery cables and batteries. The leads on the cables were too long and would crack the leads on the battery causing acid to leak inside the cables and rotting them out.

It's nice to have this bulletin as confirmation. I also wired my toggle backwards from the way it suggests. (On for Passlock Enable---Off for Passlock Disable.) Either way, it works.

hey Ray-

Gosh i wish i would have found this website sooner as i just had my Alero taken to the shop today for this very same non-starting problem. I am going to print of f some things from here and take it to the dealer later this afternoon and show them all of this. I wonder what kind of reaction i will get? Well i know where to go if i have a future problems...thanks

THIS HOW YOU DO IT .
1ST PUT KEY IN SWITCH
2ND TURN TO ACC LET IT STAY ON OF 11 MINS.
TURN IT OFF AND BACK ON TO ACC FOR 11 MINS.
TURN IT OFF AND BACK ON TO ACC FOR 11 MINS.
IT TAKES ABOUT 33 MINS TO COMPLETE P.S. DO NOT TURN
THE CAR ON ALL THE WAY JUST TO THE ACC WHEN TRYING TO RESET . AFTER THE 33 MINS IT'S OK TO START. YOU JUST RESET THE
SECURITY SYSTEM........... EMAIL fvalle@houston.rr.com

Has anyone tried this? Does it really work?

[MT-2500]

if that is what the systems needs it will work.
It is a relearn procedure for when the body or anti theft modules are replaced or it has lost it memory.
But it is key off to on not key off to acc for 10 or more minutes and the key off and repeat key on 2 more times.
You will need a good batery or a charger hooked up for the total 30 minutes key on.

Even if you turn off the radio and fans? Will it really drain the battery? Would it be safe to do the procedure then jump start the vehicle?

[ponchonutty]

It's never recomended to jump a car. It'd be better to put a battery charger on it when you go to start the car. Now, if your PK2 system is at fault and stays at fault the relearn won't help you. The same thing is if it's intermittant (like most are).

So if the problem is intermittant - which I think it is. Will reomving the battery negative terminal for 10 seconds clear the light until the problem starts again?

I can't stand the light but don't really want to shell out $400 for a repair that will just turn off a light. I have not had anyproblems starting the car.

Black tape, I got rid of my 04 malibu orange MPH always on. It is there because you can change it to KM through the DIC.

Thats good but now I have to figure out how to take off the screen that protects the instrument panel.

I put right over the shield, when the day comes that the cluster needs work then I will put it directly on the panel. Works for me.
