Understanding Your Mazda CX-5 Key Fob

Replacing the Mazda CX Five Key Fob Battery: A Step-by-Step Guide

Replacing your mazda cx five key fob battery is a straightforward process that requires minimal tools and time. You’ll need a small flathead screwdriver and a fresh CR2032 battery. Let’s walk through the steps:

Locate the small notch on the side of the key fob. This is usually opposite the key blade.
Carefully insert the flathead screwdriver into the notch and gently pry open the key fob casing. Be careful not to damage the plastic.
Once the casing is open, identify the battery compartment. The CR2032 battery should be visible.
Using the flathead screwdriver, gently pry the old battery out of its compartment. Again, avoid damaging the contacts.
Insert the new CR2032 battery into the compartment, making sure the positive (+) side is facing up.
Snap the key fob casing back together. You should hear a click indicating it’s securely closed.
