Replacing Your Mazda5 Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your Mazda5 key fob is a quick and easy process that you can do yourself, saving you a trip to the dealership. Here’s a simple guide:

Locate the small slot or notch on the side of your key fob. This is usually near the key ring attachment.
Insert a small flat-head screwdriver or a key into the slot and gently pry open the key fob casing. Be careful not to damage the plastic.
Once the casing is open, you’ll see the CR2025 battery. Note the orientation of the battery, with the positive (+) side facing up.
Carefully remove the old battery using your screwdriver or fingernail. Avoid touching the battery terminals.
Insert the new CR2025 battery into the compartment, ensuring the positive (+) side is facing up, just like the old battery.
Snap the key fob casing back together. You should hear a click when it’s securely closed.
Test your key fob to ensure it’s working correctly.
