2016 Ford Fiesta
Remote / key fob programming
Programming a remote on this Ford resets every remote for the vehicle, so you reprogram them all together. There are two common methods — try Method A first, and if it doesn't work use Method B. Do not press the brake pedal at any point.
Full steps: Ford Remote Programming: Reset and Relearn Every Remote
Key programming
You can add a new key to this Ford yourself if you already have two keys that start the engine. The new key must be cut first, and it has to be a genuine key — a cloned hardware-store key won't work.
Replacement key fobs
Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.
Proximity Key
Stays in your pocket — the car unlocks and starts without inserting a key.

Ford Fiesta key fob battery
Your Ford Fiesta key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Energizer CR2032 Lithium Coin Batteries (4-pack) on AmazonHow to replace the battery
- 1 Slide the release latch and pull the metal emergency key out of the fob.
- 2 Use that key (or a coin) to pry the two halves apart at the seam.
- 3 Lift out the old coin cell — note which side faces up.
- 4 Drop in the new battery the same way (printed + side usually faces the back cover).
- 5 Press the case back together until it clicks, then test lock/unlock and push-to-start.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Even with a dead fob battery you can usually still start the car by holding the fob against the start button — check your owner's manual.
- If the fob still won't work after a new battery, it may need re-syncing or programming.
