How Does The Ford PATS System Work?

Before we learn how to bypass Ford’s passive anti-theft security system, it is essential to know how this system works. There is a special chip inside this car alarm system. This chip is also directly linked to your key fob. When you press the button on the vehicle key fob, the signal reaches the chip inside the anti-theft security system, and it disengages the alarm. 

You may wonder why pressing the button on another key fob does not have the same impact. This is because each key has a unique electronic identification procedure. The chip will only respond to the signal emitting from the vehicle’s original key. If someone tries to operate your vehicle with a false or replica key, the engine won’t start, preventing your car from getting stolen by thieves

This feature will be handy if you park your car and you forget to lock your vehicle, the engine will only respond to the original key and not to a replica key. Or if on the streets where there is no proper security.
