How to Change Battery in Mazda 2 Key Fob

Changing the battery in your Mazda 2 key fob is a quick and easy process that can save you time and money. Knowing how to perform this simple task yourself avoids the need for a trip to the dealership or an auto locksmith. This guide will walk you through the steps to replace your Mazda 2 key fob battery, ensuring your key continues to work flawlessly.

Identifying Your Mazda 2 Key Fob and Battery Type

Before you begin, it’s crucial to ensure you have the correct replacement battery. Most Mazda 2 key fobs use a CR2025 battery, a common type readily available at most stores. However, it’s always best to double-check your owner’s manual or the existing battery in your key fob to confirm.

Gathering Your Tools

You’ll need minimal tools for this task: a small flat-head screwdriver or a similar tool to pry open the key fob and the new CR2025 battery. A small tray or container can be helpful to keep the small parts organized during the process.

Step-by-Step Guide to Changing the Battery

Locate the small release button or slot on your key fob. This is typically on the side or back of the fob.
Carefully insert the flat-head screwdriver into the slot and gently pry open the key fob casing. Avoid using excessive force, as this could damage the plastic.
Once the casing is separated, you should see the CR2025 battery. Note its orientation.
Gently remove the old battery. You can use your screwdriver to carefully lift it out.
Insert the new CR2025 battery, ensuring it is positioned correctly, matching the orientation of the old battery.
Close the key fob casing by pressing the two halves together until they snap securely back into place.
