What You’ll Need to Change Your Mazda CX-5 Key Fob Battery

Before diving into the process, gather the following:

A new CR2032 battery: This is the standard battery for most Mazda CX-5 key fobs. You can easily find them at most convenience stores, auto parts stores, or online.
A small flat-head screwdriver: This will help you pry open the key fob casing.
Optional: A small tray or container: This can help keep the small parts of your key fob organized during the process.

Step-by-Step Guide: Replacing the Battery in Your Mazda CX-5 Key Fob

Follow these simple steps to replace your Mazda CX-5 key fob battery:

Locate the release button on the back of your key fob. It’s usually a small, indented button.
Press the release button and gently pull out the metal key. This will expose a small gap in the key fob casing.
Carefully insert the flat-head screwdriver into the gap and gently pry open the casing. Be careful not to damage the plastic tabs holding the casing together.
Once the casing is open, carefully remove the old battery. Note the orientation of the battery (positive (+) side facing up).
Insert the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up.
Align the two halves of the key fob casing and press them firmly together until you hear a click. This indicates the casing is securely closed.
Reinsert the metal key into its slot.
Test the key fob buttons to ensure the new battery is working properly.

Troubleshooting Tips

If your key fob still isn’t working after replacing the battery, here are a few things to check:

Battery Orientation: Ensure the new battery is inserted correctly with the positive (+) side facing up.
Battery Contacts: Inspect the battery contacts inside the key fob for any dirt or corrosion. If necessary, clean them with a cotton swab and rubbing alcohol.
Key Fob Programming: In some cases, you may need to reprogram your key fob after replacing the battery. Refer to your Mazda CX-5 owner’s manual for instructions on how to do this.
