How to Replace the Battery in a Hyundai Elantra Key Fob (2012 – 2013)

Introduction

Replacing the battery in your Hyundai Elantra key fob is a simple task that you can do at home. This guide will walk you through the steps to change the battery in the rectangular key fob used between 2012 and 2013. The battery you’ll need is a CR2032 coin battery, which is inexpensive and can be found on Amazon.

Materials Needed

Before you begin, make sure you have the necessary materials. Here’s a quick list:

• CR2032 battery
• Flathead screwdriver
• Precision screwdriver
• A toothpick or similar tool

Step-by-Step Guide

Follow these steps to replace the battery in your Hyundai Elantra key fob:

1. Remove the Internal Key

Start by pressing the button on your key fob to remove the internal key. This will expose a hole where the key was located.

2. Separate the Key Fob Halves

Look for a groove below the hole where the key was. Insert a flathead screwdriver into this groove and twist with a little pressure. This will start to separate the two halves of the key fob. You can continue to twist down the side until the two halves come apart.

3. Remove the Old Battery

The battery is housed in a small plastic compartment. Use a precision screwdriver or a similar tool to carefully remove the old battery. A toothpick can also work if you don’t have a precision screwdriver. Be cautious not to scratch or damage the battery housing.

4. Insert the New Battery

Take your new CR2032 battery and ensure the positive side (the side with text and information) is facing down. Slide the bottom of the battery into place, aligning it with the metal component at the bottom, then click the top into place. It should snap snugly.

5. Reassemble the Key Fob

Reconnect the two halves of the key fob by pressing them together until they snap back into place. Insert the internal key back into its slot. The light on the key fob should come on, indicating that the battery is properly installed and functional.

Where to Buy the Battery

You can purchase the CR2032 battery on Amazon for a few dollars. It’s an affordable and convenient option for getting the battery you need.

Changing the battery in your Hyundai Elantra key fob is a quick and easy process. With just a few tools and a new battery, you can have your key fob working like new in no time. Follow the steps outlined in this guide, and you’ll be able to do it yourself at home.
