Passlock System

[ponchonutty]

Why does everyone insist on doing the toggle switch???? To answer your question, yes. The light will always be on and once the system totally takes a crap you'll never start your car again. The better method is to use matching resistors and wire them inline like I constantly say to. This way if your car's battery goes dead or you have to change the battery, it'll start back up. With the toggle switch the system can fail perminately which will cause you a very big headache if the car's battery ever fails or you lose power to the bcm.

I am sooooo tired of this damn thing going off for no reason...I am a health care worker who drives from home to home and having to wait an extra ten minutes between clients cuts into my paycheque.
Anyone with any help or answers would be sooo appreciated.

I have a 1997 chevy malibu, my theft sytem came on yesterday, but i need a new engine put in my car. Once a new engine is install, would this cause the theft system problem to go away.

No, as the problem is NOT with, or, in your engine. And chances are you're not really getting a completely "new" engine... You're prob. getting a gasket changed, or new heads or something - I seriously doubt that getting the engine replaced in your car would come out financially possible, as the work alone would prob. cost more than your car is worth since its a 97. (Just food for thought).

If you are indeed going to have an engine swap most of the time it seems the problem gets worse. I have not had the time to mess with the older PK1 system to see if it can be bypassed too. Only VATS and PK2 I can do.

I feel the same way about the engine being the engine and the thelft system being the theft system. But I called up a junk yard shop and asked them about swap my engine and I also told them about the theft lock problem i have.... They told me once the engine is swap it would some how reset itself..........But I live in Philadelphia there are alot of crackhead mechanics whom are more experience than you local pepe boy mechanic, so labor here can sometimes be dirt cheap......

The shop price was $800 for getting and putting in the engine......... Plus i didn't pay for the car............It was a given to me because of the engine problem.

An engine that is ran by the PCM is totally different than the BCM which controls the theft system.

[tjr19136]

I am getting a little scared here now because I read somewhere that if you remove the battery while the car is in theft system mode, then the car is totally screwed..........So other words when this guy swap the engine and go to cut the car on the theft system problem will only get worst........

[ponchonutty]

You got it.

Can a new car key cause this problem, reason I am asking is, because I lost my orignal key car key. I never had any problems with the orignal key. I only had the new car key for about 3-4 days before it caused my car to go into this theft system mode. I noticed the origanl key a little circle on the top of it, and the new key didnt have that..................

[tjr19136]

I think my battery has died due to the cold weather,while in theft system mode...........Are you sure only a GM dealership can fix this; not even a first class alarm system person can fix this.......................

[tjr19136]

LOL, I went and got the battery charge up, and once I install the battery; I got into the car and turn the key and the car can on...............LOL, maybe I just had a dead battery the whole time or dissconnecting the battery made it reset itself?????????????

You need to verify that the PK2 system is operating correctly. If it is, you can try to do the Passlock relearn sequence and see if it'll take or not.

I am trying to do the bypass using the resistor method on 2002 Pontiac sunfire 5sp manual, but I can't seem to get a reading on the meter to find out what resistor (s) I need.
Where am I going wrong?

I followed the below procedure :

(1) Start car
(2) Cut yellow wire (security light comes on)
(3) turn car off
(4) strip yellow wire ends and part of black wire.
(5)meter between yellow (going to ignition switch) and black ground for resistance as I start car
(6) (security light is still on)
(7) turn car off
(8) solder correct resistor between yellow (going into dash) and black
(9) start car (security light is off)
