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.

Key programming
You can add a new key to this Ford-built vehicle yourself if you already have two original 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.

Key programming
This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Mazda B3000 key fob battery
Most B3000 fobs use 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 Find the seam or small slot on the edge of the fob.
- 2 Twist a coin or small flathead screwdriver in the slot to split the case open.
- 3 Lift out the old coin cell and note which side faces up.
- 4 Fit the new battery the same way (printed + side usually faces the cover), then close the case until it clicks.
- 5 Press a button or test lock/unlock at the car to confirm it works.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Try not to touch both faces of the new battery with your fingers; skin oils shorten its life.
- If the buttons still don't respond after a new battery, the fob may need re-syncing or programming.
