Understanding the Importance of Your Hyundai Elantra Key Fob
How Does a Hyundai Elantra Key Fob Work?
Your Hyundai Elantra key fob is a small yet powerful device. It uses radio waves to communicate with your vehicle, allowing you to unlock the doors, open the trunk, and even start the engine remotely. Have you ever wondered what powers this convenience? It’s a small battery inside the fob.
Signs Your Hyundai Elantra Key Fob Battery Needs Replacement
Just like any other battery-powered device, your key fob battery will also wear out over time. The most common signs include a less responsive or non-responsive key fob, having to press buttons multiple times for them to work, or the vehicle’s dashboard indicating a low key fob battery.
Step-by-step Guide to Replacing a Hyundai Elantra Key Fob Battery
Gathering the Necessary Materials
Before you begin, ensure you have the correct replacement battery. For most Hyundai Elantra models, a CR2032 battery will be suitable. In addition, a small flathead screwdriver or a coin will also come in handy.
Precautions Before You Begin
Remember, safety first! Make sure you handle the new battery with clean hands, and avoid touching the battery terminals.
Opening the Key Fob
Procedure for Older Models
For older models, you can typically pry open the fob with a small flathead screwdriver. There is a small slot on the side of the fob where you can insert the screwdriver and gently twist to open.
Procedure for Newer Models
For newer models, there’s a small silver button at the back of the fob. Press it and pull out the physical key. You will see a notch where the key used to be. Use a coin to twist and open the fob.
Replacing the Battery
Once open, you’ll see the battery. Use your screwdriver to gently lift the battery out of its slot. Place the new battery in, ensuring the positive side (+) is facing up.
Testing the New Battery
Once replaced, put the key fob back together. Now, test it with your vehicle to make sure the new battery works properly.

If your key fob is still not working after replacing the battery, it might be due to other issues. In such cases, it’s best to consult with a professional or your Hyundai dealer.
