Antitheft 1998 malibu how to disable - Malibu Chevrolet Cars & Trucks

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, or not seen at all. When the communication breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. (like it thinks it's being hot wired) The car shuts down because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. It will either turn off the starter, or the fuel injectors. The vehicle may run for 2-3 seconds before shutting down. This link explains it pretty well.

First try another key if you have one.
If that doesn't work then remove the negative wire, wait a few minutes, reconnect and try.
If that doesn't work then you might have broken cable to the ignition switch.

Why are you wanting to disable the Antitheft System??? I figure it can only be 1 of 2 things...your Antitheft System is malfunctioning and you don't want to do what it takes to repair it properly, or you are trying to steal a truck. In either case, I don't think I can help you.

That Antitheft light is the Starter Kill. Replace the Wire that you cut and Check the Starter and Starter Solinoid.

sounds like an antitheft system malfunction - check to see if light stays on after you remove the key
