How to Change Battery in Hyundai Key Fob: A Step-by-Step Guide

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock or start your Hyundai. Fortunately, changing the battery in your Hyundai key fob is a simple DIY task that can be done in minutes. This comprehensive guide will walk you through the process step-by-step, ensuring you’re back on the road in no time.

Identifying Your Hyundai Key Fob Type

Before you begin, it’s essential to determine the type of key fob you have, as the process may vary slightly. Hyundai typically uses two main types of key fobs:

  • Standard Key Fob: This traditional type features a physical key blade that folds out from the fob.
  • Smart Key or Proximity Key: These keyless entry fobs don’t have a visible key blade and allow you to unlock and start your car without taking the fob out of your pocket or purse.

Once you’ve identified your key fob type, you can gather the necessary tools and proceed with the battery replacement.

What You’ll Need

  • A new CR2032 battery: This is the standard battery size for most Hyundai key fobs.
  • A small flat-head screwdriver: This will be used to pry open the key fob.
  • Optional: A small plastic pry tool or a fingernail can be used instead of a screwdriver to minimize the risk of scratching the fob.

Step-by-Step Guide to Change Battery in Hyundai Key Fob

Here’s a detailed guide on how to change the battery in your Hyundai key fob:

  1. Locate the release button: On the back of your key fob, you’ll find a small button or switch. Press this button to release the physical key blade (for standard key fobs).

  2. Open the key fob: Carefully insert the flat-head screwdriver or pry tool into the seam where the two halves of the fob meet. Gently twist or pry the halves apart. Be careful not to use excessive force, as this could damage the fob.

  3. Remove the old battery: Once the fob is open, you’ll see the battery sitting in a compartment. Gently pry out the old battery using the screwdriver or your fingernail.

  4. Install the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up. You can usually determine the positive side by looking for the manufacturer’s markings.

  5. Reassemble the key fob: Align the two halves of the fob and press them firmly together until you hear a click, indicating they’re securely closed.

  6. Test the key fob: Once the fob is reassembled, test all the buttons (lock, unlock, panic, etc.) to ensure the new battery is working correctly.

Troubleshooting Tips

If your Hyundai key fob still doesn’t work after changing the battery, try these troubleshooting tips:

  • Check battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
  • Clean the battery contacts: Over time, the battery contacts inside the fob can become dirty or corroded. Use a cotton swab and a small amount of rubbing alcohol to clean the contacts.
  • Reprogram the key fob: In some cases, you may need to reprogram the key fob after replacing the battery. Consult your Hyundai owner’s manual for specific instructions on how to do this.
  • Contact a Hyundai dealership or qualified automotive locksmith: If none of the above solutions work, there may be a more complex issue with your key fob that requires professional attention.
