Introduction

If you own a Hyundai Elantra from 2007 to 2020, you might need to replace the battery in your key fob at some point. The process is simple and can be done at home with minimal tools. In this guide, I will walk you through the steps to replace the battery in your Hyundai Elantra key fob.

Tools and Materials Needed

Before you start, make sure you have the following items:

• CR2032 coin battery
• Flathead screwdriver

You can purchase the CR2032 battery from various online retailers like Amazon. The flathead screwdriver is essential for opening the key fob.

Step-by-Step Guide

Locate the Groove

First, look at the top of the key fob to find a small groove. This is where you will insert the flathead screwdriver.

Insert and Twist

Insert the flathead screwdriver into the groove. Give it a slight twist to separate the two halves of the key fob. Be gentle to avoid damaging the internal components.

Remove the Circuit Board

Once the key fob is open, you might notice the buttons coming out. Carefully take out the little circuit board and place it in the rubber protector that holds it all in place.

Remove the Old Battery

Using the flathead screwdriver, push on the bottom of the battery. It will start to come out, and you can finish removing it with your fingers. The battery type you need is a CR2032.

Insert the New Battery

Take your new CR2032 battery and ensure the positive side with the text is facing up. Slide it back into place, making sure it fits snugly.

Reassemble the Key Fob

Now, put the circuit board and the rubber protector back in place. Reinsert the buttons, ensuring they are correctly aligned.

Final Checks

Click the two halves of the key fob back together. The light on the key fob should come on, indicating that the new battery is working correctly.

Common Issues and Troubleshooting

Buttons Not Responding

If the buttons are not responding after replacing the battery, double-check the alignment of the circuit board and the buttons. Make sure everything is securely in place.

Battery Not Fitting

Ensure you are using the correct battery type, a CR2032. The positive side should face up when inserting it into the key fob.
