Step-by-Step Battery Replacement Process

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

1. Remove the Internal Key

First, locate the button at the bottom of the key fob. Press this button and remove the internal key.

2. Open the Key Fob

Next, find the small groove near the hole where the key was removed. Insert a flathead screwdriver into this groove. Apply a little pressure and twist to create separation between the two halves of the key fob.

You can now use your fingers or continue twisting the screwdriver to fully open the key fob.

3. Remove the Old Battery

Inside the key fob, you will find the CR2032 battery. It is housed snugly, so you may need a precision screwdriver to remove it. Insert the tool into the top corner of the battery and apply a bit of pressure to pop it out.

4. Insert the New Battery

Take the new CR2032 battery and ensure the positive side (the side with the text) is facing down. Align it with the metal component inside the key fob and push it into place.

5. Reassemble the Key Fob

Make sure the circuit board inside the key fob is properly positioned and not moving around. Place the two halves of the key fob back together and click them into place.

6. Return the Internal Key

Finally, reinsert the internal key into the key fob. Ensure it clicks securely into place.
