Replacing the battery in your Hyundai Elantra key fob is a straightforward task that can save you time and money. This guide provides step-by-step instructions to help you replace the battery easily.

Key Fob Battery Type

The Hyundai Elantra key fob typically uses a CR2032 lithium coin cell battery. This type of battery is widely available and known for its reliability and long-lasting performance.

Tools Needed

To replace the key fob battery, you will need:

  • A new CR2032 battery
  • A small flathead screwdriver or the emergency key from the fob

Step-by-Step Instructions

1. Remove the Emergency Key: Locate the release button on your key fob and slide out the emergency key. This will expose a notch that you can use to open the fob.

2. Open the Key Fob: Insert the flathead screwdriver into the notch where the emergency key was housed. Gently twist to pry apart the two halves of the key fob. Be careful not to apply too much force, as this may damage the plastic casing.

3. Remove the Old Battery: Once the fob is open, locate the battery compartment. Use your screwdriver to gently push out the old battery. Take note of how the battery is oriented (the positive side should be facing up).

4. Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring that it is oriented in the same way as the old one (positive side facing up).

5. Reassemble the Key Fob: Align both halves of the fob and press them together until they snap securely into place.

6. Test Functionality: Press any button on your key fob to ensure it works properly. If it does not respond, double-check that the battery is installed correctly.
