2014–2015 Mazda 3
Remote / key fob programming
On a Mazda without the Smart Entry system, you can program a remote yourself from the driver's seat — no tools needed.
Key programming
You can add a new key to this Mazda 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.

2004–2006, 2007, 2008, 2009 Mazda 3 key fob battery
Your 2004–2006, 2007, 2008, 2009 Mazda 3 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.
2010–2013, 2014–2015 Mazda 3 key fob battery
Your 2010–2013, 2014–2015 Mazda 3 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.
