How does Ford anti-theft work?

How Ford Anti-Theft Works
Ford vehicles are equipped with an anti-theft system called Passive Anti-Theft System (PATS), also known as Ford Securilock. This system is designed to prevent unauthorized access to the vehicle and protect it from theft. Here’s how it works:
1. Transponder Key: Ford PATS uses a key with a transponder in the head of the key. Each transponder is coded with a unique identifying code made from a possible 18 billion combinations.
2. Identification Process: When you insert the key into the ignition and turn it to the RUN/START position, the PATS control module sends out a radio frequency (RF) signal. The transponder in the key receives this signal and sends back a unique RF signal to the vehicle’s computer, confirming that the correct key is being used.
3. Authorization to Start: If the vehicle’s computer receives the correct identification code from the transponder, it authorizes the vehicle to start and continue running. This process happens in less than a second.
4. Theft Prevention: If the vehicle’s computer does not receive the correct identification code or if an unauthorized key is used, certain components, such as the fuel pump and starter, will remain disabled, preventing the vehicle from starting or running.
It’s important to note that Ford’s anti-theft system is a passive system, meaning it doesn’t require any input from the driver. The system automatically engages once you park your car, remove the key, close the doors, and lock up.
If you encounter any issues with the anti-theft system, such as the system being triggered accidentally or having trouble starting the vehicle, it is recommended to consult a professional vehicle technician for assistance.
