How to Use FORScan to Program A New PAT Key by Yourself

What is PAT Programming?
PATS is an acronym that stands for Passive Anti-Theft System (Ford also calls this SecuriLock). It is also called a transponder key. It is a security feature found on most (if not all) new Ford products, and what it does is disable your vehicle’s starter unless your specially programmed key is used to start the vehicle. There is a computer chip inside of the key, and without that you will NOT be able to start the vehicle — even if you have a regular (non-PATS) key with the correct cuts, it will not work. When replacing the Powertrain Control Module (PCM) on a PATS-equipped vehicle, a parameter reset or relearn procedure must be performed after the PCM is installed. Vehicles with PATS will not start until this on-car procedure is successfully performed.

This ProTech helps identified what type of PATS your vehicle may have and what steps and

equipment are needed to perform the procedures.

Before attempting a PATS relearn, the replacement PCM must be calibrated to current

vehicle specification, the Flash2 All-Makes Reprogrammer can be used for this purpose.

In addition to flashing, Vehicle Identification Block programming may be required for

some applications.
