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.

SOURCE: replacing ignition switch in 2001 chevy silverado

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.

2005 chevy classic new lock and keys starts and runs if off more then 10 minutes antitheft comes on and have to wait 10 minutes starts again any idea?


Yeah , take it to a qualified repair shop. You have a anti-theft system problem . Need to have code's pulled
DTC B2947
DTC B2948
DTC B2957
DTC B2958
DTC B2960
DTC B3031
DTC B3033
DTC P1626
DTC P1630
DTC P1631
DTC P1632

This will point to a diagnostic procedure .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock™ System are as follows:
• The ignition lock cylinder and key
• The ignition lock cylinder case, including the Passlock™ sensor
• The ignition switch
• The body control module (BCM)
• The security indicator on the instrument cluster
• The powertrain control module (PCM)

Changing the Passlock™ Components
The following components contain codes or passwords, or must learn codes or passwords for the Passlock™ System to allow the vehicle to start:
• The ignition lock cylinder case
• The body control module (BCM)
• The powertrain control module (PCM)
If any of these parts are replaced, a learn procedure must be performed. Refer to Programming Theft Deterrent System Components . If parts are replaced and a learn procedure is not performed, the engine will crank and will not run or will start and stall immediately.

The engine starts and dies immediately. I have just changed the starter switch and starter switch housing. 2001 Chevy Silverado 5.3 Does the system need to be coded?


See if the fuel pump is working. Turn the key on and listen by the gas tank if you hear the pump working. Mine was still working but didn't have enough pressure to keep the truck running. You might want to test the fuel pressure.

Pass lock problems


Your Passlock may need to relearn the ignition keys, if the ignition lock has gone bad like my in-laws Grand Am Gt, here is what i did so they will not get stranded any more. Buy a Passlock by pass module for around $70.00. You can order one from GMPASSLOCK.COM in the mean time try resetting the Passlock. Good luck

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure
1.) Turn ON the ignition, with the engine OFF.
2.) Attempt to start the engine, then release the key to ON; the vehicle will not start.
3.) Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF.
4.) Turn OFF the ignition switch, and wait 5 seconds.
5.) Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes.
The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
6.) Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
