Understanding Your Ford Focus Anti-Theft System
The Ford Focus anti-theft system, also known as the Passive Anti-Theft System (PATS), is designed to prevent unauthorized starting of your vehicle. It uses a transponder chip in your key fob that communicates with the vehicle’s computer. If the computer doesn’t recognize the chip, the engine won’t start. While it’s a vital security feature, it can sometimes malfunction, triggering false alarms and preventing you from starting your car. Understanding its nuances can save you time and headaches.
