The PATS (Passive Anti-Theft System) key, also known as the transponder key, is a security feature from Ford that disables your vehicle's starter unless a specially programmed key is used. A PATS key is equipped with a computer chip that prevents non-PATS regular keys, even with the correct cuts, from working.    

One convenient way to program a new PATS key is via FORScan. A video created by SY Diagnostics shows how to properly program a PATS key on a Ford C-Max using FORScan. Check it out at the video below:

Programing a new PATS key requires replacement keys that can be purchased via your dealer or a 3rd-party seller. The replacement key should be compatible with your vehicle in order to work. For vehicles equipped with PATS I technology, you will need to program using one working replacement key. For PATS II, programming a new PATS key requires two working keys, this would ensure and protect vehicle owners that only they can program duplicate keys.
