The 2012–2018 Focus uses the same key setup, so everything on this page applies to those years too. The full picture is on the Ford Focus key guide.

Same key system as the 2012–2018 Focus

Ford kept the Focus's key system unchanged across 2012–2018, so everything about replacing a 2016 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our Ford Focus key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on Ford programming in general on our Ford key page.
