Changing the battery in a Hyundai key fob is a straightforward process that many car owners can handle themselves. This guide is aimed at Hyundai vehicle owners who are looking for a simple, step-by-step method to replace the battery in their key fob. By following these instructions, you can ensure that your key fob operates smoothly and efficiently.

Steps to Change the Battery in a Hyundai Key Fob

Step 1: Gather Necessary Tools

You will need:

  • A new CR2032 battery
  • A flathead screwdriver or the mechanical key from your fob

Step 2: Remove the Mechanical Key

To access the battery, start by removing the mechanical key from your key fob. Press the button or tab on the fob to release it.

Step 3: Open the Key Fob

Using the mechanical key or a flathead screwdriver, locate the small slot where the key was housed. Insert the key or screwdriver into this slot and gently twist to pry open the two halves of the fob. Be careful not to apply too much force to avoid damaging the plastic.

Step 4: Remove the Old Battery

Once open, you will see the circuit board and battery. Gently lift out the old battery using your fingers or a small tool, noting its orientation (the positive side should be facing up).

Step 5: Insert the New Battery

Take your new CR2032 battery and place it in the same orientation as the old one. Ensure that it is seated properly and making contact with all necessary connections.

Step 6: Reassemble the Key Fob

Carefully align both halves of the fob and press them together until you hear a click, indicating they are securely closed. Reinsert the mechanical key into its slot.

Important Tips

  • Check Battery Orientation: Always ensure that you place the new battery in with the correct orientation; typically, this means having the positive (+) side facing down.

  • Use Quality Batteries: Opt for high-quality batteries to ensure longevity and performance of your key fob.

  • Test Functionality: After reassembly, test your key fob to make sure it works correctly before relying on it.
