The modification at www.bergerweb.net works only on vehicles with Passlock II systems.
1999 - 2004 Oldsmobile Alero
1997 - 2003 Chevrolet Malibu
1999 - 2004 Pontiac Grand Am
A few Saturn models around the same years.
 
If you can get hold of a service manual for your '97 Grand Am, find the page that shows the wiring diagram for the theft deterrent system. Scan the pages and then send them to me at richardbergerweb.net. Also, Find the relearn procedure in your Owner's Manual and see what they tell you to do. If the procedure is the same, then you may possibly have a variation of the Passlock II system.
 
Finally, Check your key, and see if it is stamped on one side with a "+" sign inside a circle. If not, then your key doesn't have any imbedded circuits.

I do have a service manual that's for my car and a few others in the 97-99 range I believe. I will see if I can find a diagram and get it sent to you. I'm not sure I have an owners manual but I will check. No + on the key. Thank you for the help. I'm just at an end with this.

Hi,
 
Thank you for all the advice and assistance. I was lucky enought to be able to afford a new vehicle . I don't have the time or patience to try and deal with trying to fix the car at this point in time so I donated my car to the Breast cancer foundation. Hopefully they can make something off of it and help people at the same time.
 
Have a great day and thanks again!

If your light is on (solid) that means that there is a fault in wiring between your bypass module and the Body Control Module. Go back to the website, and follow the directions near the end of the article for troubleshooting for wiring problems. If you find that there is an open, or a short in your wiring, move your bypass module from the Ignition area to the BCM area. Refer to the circuit diagrams at the bottom of the article. Instructions for doing the bypass at the BCM can be found at:
http://bergerweb.net/grandamsecurityfix.htm
You can still use your bypass module, so you won't have to solder the wires.

I looked through the service manual I have and there is no wiring diagram for the passlock. The service manual seems more a general manual for several make and models of gm cars. Lately since the ignition switch replacement which seemed to work for a couple weeks the car has been passlocking but usually after a few minutes all the lights come back on and the theft light flashes and goes off and car will start. Until tonight. Went to take my husband to work after a few days of no issues with the car it decides to passlock again. This time tried to do the relearn and got nowhere. Looks like I will have to tow it in somewhere just can't afford to keep fixing it temporaly

Thanks for posting this. I will be doing the mod today. Was just wondering while driving when those lights come on my turn signals click, the electric door locks click etc. Was wondering if this will fix that too. Thanks alot!
 
It's a 2004 Grand Am.

You seem to have other issues that are not necessarily related to a Passlock problem, but all of the things you describe are controlled by the Body Control Module. It is more likely that you either have a faulty BCM, or there is a wiring problem in your dashboard that is causing the BCM to do funny things. The most likely area of concern is a bad ground Splice Pack on the circuits that furnish ground to the Body Control Module. I would start by checking the integrity of Splice Pack SP202. You will need a service manual with wiring diagrams for your vehicle. The service manual will also tell you where to locate SP202. This is not an impossible task, but it will take patience to do the troubleshooting.
Considering that you are having other problems that are related to the BCM, I would doubt that doing the Passlock mod will help.

The car has been making those clicking sounds since shortly after I bought it in 2005. If I turn the turn signal on or the hazards on, the clicking quits. It is very intermittent. The techs told me it was some assembly unit and it would be like 350-400 to fix.
 
I didn't get your message until after I did the mod. Cut the yellow/black made the circuit like you showed and I still have a security light. Did the 10 min and 30 min and still a light. I'm just gonna drive it with the light on and hope that it just won't stop starting. LOL My Service Engine Light Soon light has been on for 3 or 4 years and the techs can't find anything either, so I'm not worried about a light.
