Question about 2000 Chevrolet Silverado 1500
The security, antitheft, or passlock light 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 misinterperates 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.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.
