Remote / key fob programming
This remote 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 remote, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement remote 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 RX-8 key fob battery
Your Mazda RX-8 key fob uses a CR1616 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Panasonic CR1616 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.
