Introduction

Replacing the battery in your Kia Optima key fob can seem daunting, but it’s actually a simple task you can do at home. This guide will walk you through the steps to change the battery in your key fob, which covers models from 2014 to 2020.

You will need a CR2032 battery and a flathead screwdriver to complete the task. Let’s get started!

Tools and Materials Needed

• CR2032 battery
• Flathead screwdriver

Step-by-Step Guide

Step 1: Open the Key Fob

First, flip open the internal key. This will give you access to the back of the key fob. Turn it over to locate the two pieces of plastic that form the back cover.

Step 2: Remove the Back Cover

Use your fingers to push up the back cover. This might be a bit difficult, but with some effort, it will come off. If it’s too tight, use a flathead screwdriver, another key, or even a coin to pry it open. Insert the tool into the area where the key is housed and gently pry up.

Step 3: Access the Battery

Once the back cover is off, you’ll see the CR2032 battery. Use your tool to wiggle in from the top. If your screwdriver is too large, opt for a smaller precision screwdriver. This will make it easier to remove the battery without damaging the key fob.

Step 4: Remove the Old Battery

Carefully pry the old battery out. Be gentle to avoid damaging the contacts inside the key fob.

Step 5: Insert the New Battery

Take your new CR2032 battery and make sure the positive side is facing up. Slide it into the compartment and click it down so that it sits flush. Ensure it won’t fall out easily.

Step 6: Reassemble the Key Fob

Click the back cover back into place. Flip the internal key back in, and you’re done!
