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.

2003–2004, 2005, 2009, 2010, 2011, 2012–2013, 2014 Mazda 6 key fob battery
Your 2003–2004, 2005, 2009, 2010, 2011, 2012–2013, 2014 Mazda 6 key fob uses a CR2025 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Energizer CR2025 Lithium Coin Batteries (4-pack) on AmazonHow to replace the battery
- 1 Find the seam or small slot on the edge of the remote.
- 2 Twist a coin or small flathead in the slot to split the case open.
- 3 Remove the old coin cell and note the + side.
- 4 Fit the new battery with the + side matching, then close the case.
- 5 Press a button to confirm the LED lights, then test at the car.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Try not to touch both faces of the new battery; skin oils shorten its life.
- If the remote still doesn't work after a new battery, it may need re-syncing or programming.
2006–2008 Mazda 6 key fob battery
Your 2006–2008 Mazda 6 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 Look for a small notch or screw on the side of the fob where the key blade meets the buttons.
- 2 Pry the housing apart with a coin or small flathead (or remove the screw).
- 3 Pop out the old coin cell, noting its orientation.
- 4 Insert the new battery the same way up, then snap the case shut.
- 5 Test the buttons — if they work, you're done.
Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
