Passlock System

[ponchonutty]

leaving the car sit for 15 minutes usually does the trick.

HELP!

I am new to this forum, but have already found it very helpful.

I too have a continuing Passlock system problem. It usually takes me 20 minutes to get my car started after the Theft System light comes on.

BUT, I have a new problem - both last night and again this morning, I started the car and about a minute into driving - the theft system light went on!

Will my car stop while I am driving? Will I be left in the middle of the highway?

Has anyone experienced this problem? What do I do?

Thanks!

Welcome to AF on your first post.

I will give you a hint. If the light is on you will have a code set that will point you to the problem.
You need to get codes checked and post codes and.
It would be better to start a new post on you problem in the proper forum.
And give us all of the info you can.

Tips on getting a good answer to your questions.
People trying to answer your question do not have a crystal ball.
So give them all of the info you have like year make and model and engine and transmission.
Also service cars engine and transmission service history or any recent repairs or problems.
Also a good description of your problem and what it is doing or not doing.
If you have codes give up the code no.
And remember a code does not say replace the part but only points to the problem that you have to check out.
So to better help you give up all of the info you have on it.

Thank you. I thought I was posting to the proper group - since my problem is with the passlock system.

And I don't understand the hint - I don't understand about codes.

As I said - I have had the same problem - having to wait 20 minutes to start my car - but I asked why the theft system light went on and stayed on after the car started.

Where and how would you suggest I post this question on the forum?

Thanks

If the anti theft light is on you will have a code set in the body computer.
You need to get tthe code checked with a body computer capable scanner.
Good repair shop or dealer can check it for you
This post is old but you can read threw itfor info on it.
But You should start a fresh post on your car and problem.
To many different people on one post can get confusing with two many different answers.

You need to go to the forum of the car you have and look for the New Tread button upper left side and start a new post for your problem.

Any advice is very much appreciated.

HEY TRY TO RESET YOUR SYSTEM .
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

Make sure to have a battery jumper or charger ready because the POS oem battery won't hold up to that.

My security light comes on and disables my car about once a year. Bypassing the system sure sounds like the way to go. I have found that cleaning the ignition switch with electronics cleaner fixes the problem until ignition gets dirty inside again. To clean ignition: wrap key with very thin paper or cloth, soak it with electronics cleaner and insert key and leave it in a few minutes. Remove key and cloth/paper and it will be black from dirt, etc. This has always fixed my problem until it gets dirty again. Takes about a year for it to happen again.

Important: Use tissue paper that will not come apart when wet with cleaner. I use the paper they put in some boxes of new shoes. You can buy the cleaner at large retail stores like WM.

I figure my car has to be similar to many other GM vehicles. I have never had any parts replaced concering this.

Using compressed air works as well too but eventually the magnets inside either wear out or move making the whole system dead therefore needing to be bypassed or repaired.

Just wanted to thank you, this bypass works great. The only problem that someone may encounter is if your battery goes dead, you need to have that lock cylinder work "one more time" to start the car, then disconnect it again. It needs to set that code to take the system off line. I did it for a friends car that was acting up. You can take it a step further and pull the dash and remove the bulb for the light too.

Well, I just bypassed one the other day too. What I did was cut the yellow PK2 wire, stripped a little off of the black reference ground wire, put one lead from my ohm meter on the black ground wire and the other lead on the wire yellow wire going to the ignition switch. Then I put the car in gear and cranked it over. When you do that, the switch will send out what code it has been using. It came out to something like 6.21ohms. I then got some resistors that were about 6.25 and connected one end of the resistors to the cut yellow wire GOING to the BCM and the other end of the resistors to the ground reference wires. It started right up and the theft light went off.

To start with I have a 2001 Impala with NO chip in my key. I have read how to disable the passlock security after having the car running. Is there any way to temporary bypass the THING when it won't start without having to have the security light On all the time by using the cutting of the yellow wire trick? i.e. instant start!

Right. No PK1 or PK2 system has a "chip" in the key. It's all in the lock mechanism itself. It uses cheap little magnets inside it. Usually they get cruddy or even move if the cyl. is worn enough to rub up against them. That's why the problem is always constant.

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.

I like this method over the toggle, would it work on an '03 Impala?
