What Is Ford PATS?

In Ford cars, a PATS system means a Passive Anti Theft System. The main purpose of this system is to prevent Ford cars from being stolen.

However, PATS is not in all Ford models before 1996.

How Does Ford PATS Work?

How to Bypass Ford PATS System Without Key

A Ford key has an RFID chip in it. There is communication between this chip and the transponder inside the steering column of your Ford car. Each Ford car has a unique RFID code.

PATS can also be known as Ford Securilock. After inserting your key in the ignition, a theft light comes up for a moment, and PATS gets activated.

The fuel pumps and injections are powered by the PCM, while the PATS controls the detection of fake keys.

Only original keys have an RFID chip, so if a fake key is inserted, there won’t be communication between the transponder and the RFID chip.

This enables the system to know you are using a fake key, and the car won’t start.

  • New Keys- The new one has to have the same shape and size as the original key.
  • Flathead screwdriver- This will help you to remove the chip from the original key.

Step 2: Remove the Transponder

Bypassing the PATS system is set if you get the chip and a look-alike key.

Everything will be ready if you can remove the chip from the chip key without causing damage. These steps will guide you on how to remove the RFID chip from the original key:
