SOURCE: gm passlock security system how to disable

Wiring diagrams can be found online, however i believe you can re-learn the key by leaving it inside the ignition tumblen and switch it to accesory. Then disconnect the b attery for about ten minutes and then try starting the car without taking the key out.

How do i bypass pass lock on 2002 saturn vue


This is a very common problem on GM vehicles. The security system is known to fail. Basically when you insert your key, the system checks for certain signal. If the system cannot get the correct signal from the key, it assumes the key is incorrect and goes into SECURITY lockout mode. (prevents hotwiring) This has been happening with GM's for a very long time. There are ways to bypass this now. Read through this page for info, solutions as well.

How to disable the security anti theft system in a 2002 pontiac grand am


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

HOW TO DISARM SECURITY SYSTEM


The system is automatic and disarms as soon as the key is used or the remote. If it is locking you hurt then it has a fault in the system and you need to have the security system scanned by the GM dealer to see what is locking you out.
