How to Replace the Battery in a Hyundai Ioniq Key Fob (2017 – 2020)

Introduction

Replacing the battery in your Hyundai Ioniq key fob is a straightforward process. With just a few tools, you can easily do it yourself at home. In this guide, I’ll walk you through each step to ensure your key fob works perfectly.

What You Need

Before we start, gather the following tools and materials:

• Flathead screwdriver
• CR2032 battery
• Precision screwdriver (optional)

You can purchase the CR2032 battery online. It’s inexpensive and convenient.

Step 1: Remove the Internal Key

First, locate the button on your key fob. Press this button to release the internal key. Once the key is out, you will see a keyhole and a small slot next to it.

Step 2: Open the Key Fob

Insert your flathead screwdriver into the small slot. Twist the screwdriver gently to start separating the two halves of the key fob. Work your way down the edges, twisting as you go until the key fob is completely open.

Step 3: Remove the Old Battery

Inside the key fob, you will find the battery housed in a small plastic area. To remove it, use a precision screwdriver or a smaller flathead screwdriver. Carefully pry the battery out by pushing down into the small space beneath it and lifting it out.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side (the one with text and information) is facing down. Position the battery into the metal component and click it into place. The battery should sit flush within the compartment.

Step 5: Reassemble the Key Fob

Once the new battery is in place, align the two halves of the key fob and press them together until they click. Insert the internal key back into its slot.

Step 6: Test the Key Fob

If the battery is correctly installed, the light on the key fob will illuminate, indicating that the key fob is functioning properly. If there’s no light, double-check the battery placement and try again.
