Step-by-Step Guide to Replacing Your Mazda CX-5 Key Fob Battery
1. Locate the Battery Compartment:
- Examine your Mazda CX-5 key fob. The battery compartment is usually located on the back of the key fob, either behind a small sliding cover or secured by a few screws.

2. Open the Key Fob:
- Sliding Cover: If your key fob has a sliding cover, gently slide it open.
- Screws: If your key fob is held together by screws, use your flathead screwdriver or coin to carefully remove them.
3. Remove the Old Battery:
- Once the key fob is open, you’ll see the old battery.
- Gently pull the old battery out of its compartment.
- Important: Note the orientation of the positive (+) and negative (-) sides of the battery. This is crucial for installing the new battery correctly.
4. Install the New Battery:
- Take your new CR2032 battery and align the positive (+) and negative (-) sides with the corresponding markings in the battery compartment.
- Gently press the new battery into place until it clicks securely.
5. Close the Key Fob:
- If your key fob has a sliding cover, slide it back into place.
- If your key fob was held together by screws, carefully screw them back in.
6. Test Your Key Fob:
- Press the unlock button on your key fob. If it works, you’ve successfully replaced the battery!
- If the key fob doesn’t work, double-check that the new battery is installed correctly.
