Understanding Your Key Fob

Hyundai Tucson key fobs typically use a CR2032 battery, which is a common lithium coin cell battery. It's essential to ensure you have the correct battery type before starting the replacement process.

1. Gather Materials

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

- New CR2032 battery

Locate the button on your key fob that releases the physical key. Press this button and slide out the metal key.

3. Open the Key Fob

Insert the metal key or flathead screwdriver into the small slot next to where the physical key was housed. Gently twist to pry open the fob. Be careful not to apply too much force, as this could damage the casing.

4. Remove the Old Battery

Once opened, you'll see the circuit board and battery. If necessary, use a small tool to gently lift out the old battery. Be cautious not to touch any electronic components.

5. Insert the New Battery

Take your new CR2032 battery and insert it into the compartment with the positive (+) side facing up. Ensure it fits snugly in place.

6. Reassemble the Key Fob

Align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.
