Anti-theft system wont allow my vehicle to start

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.

Tampering with the anti-theft system can lead to damage to the vehicle or may even be *******. If you have lost your key or are having trouble starting your vehicle due to the anti-theft system, it is recommended that you contact a professional locksmith or a Ford dealership for assistance. They may be able to help you get a replacement key or repair the anti-theft system to allow you to start the car. It is important to follow proper procedures to ensure the safety and security of yourself and your vehicle.

PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related No Start issues.
