How To Program A Ford PATS Key

Ford’s PATS key system was developed to prevent vehicle theft by using a computer chip within the key. PATS stands for Passive Anti Theft System. Ford utilized the PATS key system in many vehicles throughout the late 1990s and early 2000s. Within the key is a computer chip programmed to a particular code. Your Ford vehicle only recognizes specific codes. If someone made a copy of your key, without the PATS system, the car would not operate.

This feature from Ford was a valuable system for many years. Still, as technology evolved, Ford moved on from the PATS key system. If you have a Ford, Lincoln, or Mercury built between 1999 and 2006, the odds are likely that your car utilizes the PATS system. If you need a new PATS key, read on as we’ll help you understand how to program a Ford PATS key to your car.
