What You’ll Need

Before you get started, gather the following items:

A fresh CR2032 battery (often found at grocery stores, electronics stores, and auto parts stores)

Identifying Your Mazda Key Fob Type

Mazda offers a couple of different key fob designs. To ensure you follow the correct instructions, it’s essential to determine which type of key fob you have.

Flip Key: This common type has a key blade that flips out from the fob body.
Smart Key: Also known as a proximity key, this type doesn’t have a visible key blade and allows keyless entry and ignition.

Locate the small release button or notch on the back of the key fob. This button or notch is typically located near where the key ring attaches.
Gently insert the flat-head screwdriver into the notch and pry open the key fob. Be careful not to damage the plastic housing.
Inside the key fob, you’ll find the battery. Note its orientation for correct replacement.
Carefully remove the old battery and install the new CR2032 battery, ensuring the positive (+) side is facing up.
Align the two halves of the key fob and press them firmly together until you hear a click. This indicates that the fob is securely closed.

Look for a small notch or slot along the edge of the key fob. This is usually located on the side.

Inside, you’ll see the battery compartment. It might be covered by a small plastic tab. If so, carefully lift the tab to reveal the battery.
Remove the old battery and insert the new CR2032 battery, ensuring the positive (+) side is facing up.
Align the key fob cover and press it back into place until it snaps securely shut.

Testing Your Mazda Key Fob

After replacing the battery, test all of the key fob’s functions, including locking/unlocking the doors and starting the engine (if applicable), to ensure it is working correctly.

Common Issues and Troubleshooting

Key fob still not working? Double-check that the new battery is installed correctly, with the positive (+) side facing up. If it’s still not functioning, there could be a different issue with the key fob itself.
Having trouble opening the key fob? If you’re struggling to open the key fob, ensure you’re using the correct release button or notch. Apply gentle pressure to avoid breaking any plastic parts. If you’re still having trouble, consider taking your key fob to a dealership or an automotive locksmith for assistance.

Replacing the battery in your Mazda key fob is a quick and easy DIY project. By following these simple steps, you can save yourself a trip to the dealership and keep your key fob functioning properly for years to come.
