Tools you’ll need:

A new CR2032 battery
A small flat-head screwdriver

Let’s get started:

Locate the key slot: On the back of your Mazda CX-5 key fob, you’ll see a small slot.
Release the emergency key: Insert the flat-head screwdriver into the slot and gently pry open the key fob.
Separate the halves: Carefully separate the two halves of the key fob to reveal the battery compartment.
Remove the old battery: Gently pry out the old battery, paying attention to its orientation (positive side facing up).
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, just like the old one.
Reassemble the key fob: Align the two halves of the key fob and press them together until you hear a click.
Test the key fob: Try locking and unlocking your car doors to make sure the new battery is working properly.

Still Having Trouble?

If your Mazda CX-5 key fob isn’t working even with a new battery, don’t despair! Here are a couple of things to try:

Check the battery orientation: Make sure the positive (+) side is facing up. It’s a simple mistake that can easily be overlooked.
Clean the battery contacts: Over time, the battery contacts inside the key fob can get dirty or corroded. Use a cotton swab and a bit of rubbing alcohol to clean them gently.
