Problem with theft prevention system and will not crank

When the anti-theft system in your car is activated, it is designed to prevent unauthorized access to the vehicle and protect it from theft. The specific features and functions affected by the activation of the anti-theft system can vary depending on the make and model of your car. However, here are some common ways in which the anti-theft system can impact your vehicle:

1. Ignition Interlock: In many vehicles, the anti-theft system can prevent the engine from starting or cut off power to the ignition system. This is often the primary function of the anti-theft system to deter thieves from driving the vehicle.
2. Key Removal: Some anti-theft systems can also lock the key in the ignition switch, making it difficult or impossible to remove the key when the system is activated.
3. Door Locks: The anti-theft system may lock or unlock the doors automatically when it is activated. This can be intended to prevent unauthorized entry.
4. Windows and Sunroof: In some cases, the anti-theft system can disable the power windows and sunroof to prevent someone from gaining access to the interior through these openings.
5. Alarm Activation: If your vehicle is equipped with a security alarm system as part of the anti-theft system, it may activate the alarm if unauthorized entry is detected or if someone tries to tamper with the vehicle.
6. Vehicle Immobilization: Some advanced anti-theft systems can immobilize the vehicle by cutting off fuel or electrical power to the engine.

If you're experiencing issues with your key not coming out, windows not rolling down, and the sunroof not opening, it's possible that these problems are related to the activation or malfunction of the anti-theft system. However, it's essential to consult your vehicle's owner's manual or contact the manufacturer or a qualified automotive technician for specific information about how your vehicle's anti-theft system operates and to diagnose and resolve the issues you're facing.

In many cases, anti-theft system problems may require specialized equipment and knowledge to diagnose and repair, so seeking professional assistance is often the best course of action.

Anti-theft system , is the security light lit on the instrument cluster ?

The vehicle theft deterrent system is designed in order to prevent vehicle theft by disabling the fuel injectors unless the lock cylinder is correctly engaged by a mechanical key. The theft deterrent system uses the following 4 components for theft prevention:
• The lock cylinder
• The ignition switch
• The body control module (BCM)
• The powertrain control module (PCM)
When starting the engine, the PCM searches for a password from the BCM through the Class 2 serial data circuit. If the password is not recognized or not present, the PCM will disable the engine. Two modes of tamper detection are provided:
No password received
The engine will start and stall quickly. SECURITY telltale will flash on the instrument panel cluster (IPC) and then stay ON steady.
Incorrect or disable password received (More than 3 invalid passwords are received)
The engine is disabled for at least 10 minutes and the SECURITY telltale will illuminate solid on the IPC during the 10 minutes.
After the vehicle has passed theft detection, the PCM will continue normal operation.
Auto Learn
Time required, approximately 10 minutes.
Insure that the battery is fully charged.
Use the scan tool in order to clear the DTCs.
Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
Leave the ignition switch in the ON position while observing the security indicator.
When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
The BCM and the PCM will learn the new code on the next start attempt.

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.

If you have a security light on your vehicle will not crank over !
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. The VTD system prevents vehicle operation if a valid (learned) transponder PASS-Key?®III (PK3) ignition key is not used to start the vehicle. The theft deterrent control module has an exciter that is part of the theft deterrent control module as an assembly. The PK3 key has a transponder embedded in the plastic head of the key. The exciter is an antenna which is made up of wire coils which surround the ignition lock cylinder. The PCM enables the engines starter and fuel delivery system when it receives a valid (learned) password from the theft deterrent control module via the class 2 serial data circuit.

Possibly a failing security/antitheft system. When it fails, it will turn off the starter because it thinks it is preventing theft of the vehicle, Symptoms sound right.
