I comprisized my security by destroying my ignition how do i disable pass key system

before you do damage and or disable your ride go to dealer or authorized locksmith and have a key cut using vin will be cheaper than destroying your ignition system +

Passlock™ System
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)

You can not by pass anything , system will not let vehicle start

Theft Deterrent System
The Theft Deterrent System on this vehicle is comprised of two separate systems, the Personal Automotive Security System (PASS-Key?® III) and the Content Theft Deterrent (CTD) system. These system are described and diagnosed separately within this section. For CTD operation, refer to Content Theft Deterrent (CTD) Description .
SECURITY Indicator The yellow indicator SECURITY on the instrument cluster is controlled by both the PASS-Key?® III system (VTD module) and the CTD system (RIM).
?€¢
PASS-Key?® III system, the VTD commands the instrument cluster to control the indicator only when the ignition switch is ON.

?€¢
CTD system, the RIM commands the instrument cluster to control the indicator only when the ignition switch is OFF.
PASS-Key?® III System The PASS-Key?® III system is designed to help prevent vehicle theft by disabling the engine unless an ignition key with a specific electrical value is used in the ignition lock cylinder. The PASS-Key?® III system operates independently of the CTD system. Protection is provided even if the CTD system is not armed. The components of the system are the ignition keys (black or gray), ignition lock cylinder, Theft Deterrent (VTD) module, Reader Exciter, Powertrain Control Module (PCM) and two starter relays (START 1 and 2) in the underhood fuse block.

There is no reset button.
The problem could be the anti-theft system which would knock out the injectors and spark to the plugs.
If the security light is staying on, the problem could be the chip in the key.

It is tied into the pass-key system that disables your car as part of vehicle security. You would have to by pass the pass key system which would make it vulnerable to theft as any duplicate key or broken ignition could start the car. In my estimation if it ain;t broke don't fix it or you might wind up with an inoperable car. There is more than mechanics involved ...codes and software programmed into the bcm will disable the starter, pump and injectors.

your local radio installation shop should have a bypass module

Check your mechanics manual. There is most likely a sequence of times you must turn your vehicle on, then turn the key back one click. you can actually hear the module trying to reprogram itself. If a vandal was at fault and damaged anything, you may have to take it to a mechanic. My daughters Chevy Venture was stolen and destroyed. Little by little we put things back in order..glass/modules/ignition etc. I was not able to reset the system, and had to take it to a dealer. Still cheaper than a replacement van though. Good Luck! :)

Have it checked for DTC'S - diagnostic trouble code's . I suspect the problem is with the tdm module or the ignition switch ???? Assuming will only get you into trouble . If the PCM - engine computer does not see the right coded meassage from the TDM it won't turn on the fuel injectors or it will cut them off in two seconds . .

Ignition Key With Wrong Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs one of the two following actions when you attempt to start the vehicle with a wrong ignition key:
• There are 15 PASS-Key® II resistance ranges. The PASS-Key® II resistance may be one of the 14 valid but incorrect PASS-Key® II resistance ranges. The theft deterrent module will perform the following actions when you attempt to start the vehicle (if the condition is present during an engine start attempt or for 1 second any time after the engine has started):
• Turns on the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit
• The password disables fuel delivery to the engine.
• Disables the theft deterrent relay, which disables the starter circuit
• Disables sampling of the PASS-Key® II resistance for 3 minutes
• The 3 minute time period is called the shut-down period.
• Disconnecting the battery will not clear the timer sequence. The timer sequence will resume when battery power is restored.
• Inserting the proper key during the vehicle shut-down period will not start the engine. The engine will not start until the shut-down period has elapsed.
• After the shut-down period, the engine will start if the correct ignition key resistor pellet is used.
• The PASS-Key® II resistance may be correct and allow the engine to start. Later during the same ignition cycle, the PASS-Key® II resistance may be one of the 14 valid but incorrect resistance ranges. The theft deterrent module will perform the following actions:
• Enters the fail-enable mode
• Turns ON the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit when more attempts to start the engine occur
• The password allows the fuel enable circuit to deliver fuel to the engine.
• Enables the theft deterrent relay, which also enables the starter circuit.

Ignition Key With Correct Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs the following actions when the correct ignition key is used in order to start the vehicle:
• Enables the theft deterrent relay. The theft deterrent relay enables the starter unit.
• Sends a password to the Powertrain Control Module (PCM) through the fuel enable signal circuit. As a result, the PCM allows fuel delivery to the engine.

GM VATS Key Resistor Key Security Bypass

I had this same problem & cause was an aftermarket security system that was disabled by previous owner but never removed & therefore backfed 14.5volts into ignition system over time & destroyed it.Fix is replace ignition control module,computer control module & ignition wiring harness,also I must add that reprogramming is also required for modules & both keys.Unless you know a GOOD GM mechanic who will do this on the side & get you the parts at his cost,this is a COSTLY fix at dealer $900-$1200,about 6-8hrs labor.
