I think GM uses a private firm to do their security but I'M NOT SURE .
probably your security system . Search google for "Bypass GM Vats Security"
Yes. When your GM security system activates, it disables fuel delivery to prevent startup.
Passlock security system needs repair - gm dealer only as reprograming is part of the fix
passlock system needs repair, tow it to a GM dealer. They usually replace the lock cylinder & reprogram the security system. $500.oo-$600.00
The security system is activated all the time unless the proper key is in the ignition its part of the gm vatsII system, the only time you will see the light on is if there is a problem with the resistor pellet in the key being out of range or if there is a problem with the computer that runs the system also known as the vats II brain. there is three parts to the system if you look up gm security system or vats II on the internet it will explain everything in detail and give diagrams.
Go to the gm service center nearest you with title/proof you own this vehicle, and probably pay to have a gm technician utilize a gm scan tool to re-set the security system between the radio and the pcm.
My first thought was there might be a fuse that controls it but I would contact a GM Dealer's service department if I were you.
Check to see if the security light is on, on the dash. Could be a passlock system problem and if it is the GM dealer is the only one to fix it & reprogram the system
I am a gm service manager and there have been no security system recalls on 02 grand ams i have a 2002 grand am as well and my security systems keeps acting up it will activate then i cant use car because it wont turn off then i have to get it towed in and they reset it they showed me how to but it still doesn't work for me No need for a tow you sit in your car for 10 minutes until the security light goes off then you can start your car again. Its poor parts that GM choose to use. I love my Grand Ams ( on the 5th one)
To disconnect the GM Goodwrench security system in a Chevy G20, locate the security module, typically found under the dashboard or near the ignition switch. Disconnect the wiring harness from the module, ensuring the battery is disconnected beforehand to avoid any electrical issues. If you're unsure, consult the vehicle's service manual for specific instructions and diagrams related to your model year. Always consider professional assistance if you are not comfortable performing this task.
Supposedly there are bypass modules....some are so that the remote start systems can function with the security system in the car....others are just strictly to bypass the security system intirely. I have seen some websites that sell these modules such as Ebay but there are some more specific car sites that sell them too. I have read a few things on this recently and it looks as though GM has used the Passkey I, II and III systems. The year, make and model of the car depends on what system was used and what type of bypass you will need.
Short answer is you don't. Get the unit towed to a GM dealer for repair if required. The pass key system is integrated into the engine management computer and is nearly impossible to bypass successfully.
