Introduction

Replacing the battery in your Hyundai Elantra GT key fob is a straightforward process that you can do yourself. This guide will walk you through each step, ensuring your key fob is back in working order in no time.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials. This will make the process smoother and more efficient.

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

You can purchase the CR2032 battery on Amazon.

Step 1: Remove the Internal Key

Start by flipping your key fob over to the back. Locate the small lever that releases the internal key and push it down. This will allow you to remove the key from the fob.

Step 2: Open the Key Fob

With the internal key removed, find the groove where the key was housed. Insert a flathead screwdriver into this groove and give it a small twist. This action will begin to separate the two halves of the key fob.

Continue to work your way down the groove, twisting the screwdriver until the key fob is completely open.

Step 3: Remove the Old Battery

Once the key fob is open, you will see the CR2032 battery inside. You can push the battery out with your finger or use the flathead screwdriver to gently pry it loose.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure that the positive side (the side with the text) is facing up. Slide the battery into place until it is secure and does not move.

Step 5: Reassemble the Key Fob

If the rubber piece with the circuit board comes out during this process, make sure to put it back in place. Then, reattach the two halves of the key fob, ensuring they click back together securely.

Finally, insert the internal key back into the fob. Check to see if the light on the key fob comes on, indicating that the new battery is working.

Conclusion

Replacing the battery in your Hyundai Elantra GT key fob is a simple task that can save you time and money. By following these steps, you can ensure your key fob is functioning properly.
