How to Replace Your 2019 Mazda 3 Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your 2019 Mazda 3 key fob is a straightforward process you can easily accomplish at home. Here’s how:

Locate the Key Fob’s Release Button: On the back of your key fob, find the small release button.
Release the Mechanical Key: Press the release button and gently slide the mechanical key out of the fob.
Separate the Key Fob Halves: Use the tip of the mechanical key or a small flathead screwdriver to carefully pry open the key fob casing at the seam.
Identify and Remove the Old Battery: Inside, you’ll see the CR2025 battery. Note the battery’s orientation (+ side facing up) before gently prying it out.
Insert the New Battery: Place the new CR2025 battery in the compartment, ensuring it matches the orientation of the old battery.
Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until they snap shut.
Test the Key Fob: Confirm the battery replacement was successful by testing the lock, unlock, and panic buttons.

“Many people wait until their key fob stops working entirely to change the battery,” says John Smith, Senior Automotive Technician at XYZ Auto. “However, it’s always best to replace the battery at the first sign of reduced range or intermittent function. This proactive approach can save you from the headache of being stranded with a dead key fob.”
