Replacing the battery in your Hyundai key fob is a straightforward process that can save you time and money. This guide provides clear instructions for various Hyundai models, ensuring that you can easily perform this maintenance task yourself.

Understanding Your Key Fob

Hyundai key fobs typically use a CR2032 or CR2025 lithium coin cell battery. Knowing your specific model's battery type is crucial, as using the wrong battery can lead to malfunction.

Materials Needed

  • New battery (CR2032 or CR2025)
  • Small flathead screwdriver or your car's mechanical key
  • Clean cloth (optional for cleaning contacts)

Step-by-Step Instructions

Step 1: Remove the Mechanical Key

Locate the small button on your key fob that releases the mechanical key. Pull it out to access the internal components.

Step 2: Open the Key Fob

Find a small notch or slot next to where the mechanical key was housed. Insert the flathead screwdriver or the mechanical key into this slot and gently twist to pry open the two halves of the fob. Be careful not to apply too much force, as this could damage the casing.

Step 3: Remove the Old Battery

Once opened, locate the battery inside. Take note of its orientation (which side is positive). Use your screwdriver to gently lift and remove the old battery from its compartment.

Step 4: Insert the New Battery

Take your new battery and insert it into the compartment, ensuring that it matches the orientation of the old battery (positive side facing up). Press down gently until it clicks into place.

Step 5: 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. Make sure there are no gaps along the edges.

Step 6: Test Your Key Fob

Finally, test your key fob by pressing each button to ensure it functions correctly. Stand near your vehicle and check if you can lock and unlock doors from a distance.

  • If your key fob does not work after replacing the battery, try reprogramming it according to your vehicle's owner manual.
  • Dispose of old batteries properly at designated recycling centers.
  • Consider purchasing batteries in bulk for future replacements, as they are relatively inexpensive.
