How To Open A Hyundai Key Fob & Replace The Battery

You’ll need to know how to open your Honda key fob before replacing your Hyundai key fob’s battery. This is an easy task, but it could vary depending on the model year of your Hyundai vehicle.

Step-By-Step Guide: How To Open A Hyundai Key Fob

  1. Remove the mechanical key by pressing and holding the release button.
  2. Use a slim tool or utility blade to pry open the key fob cover. Do your best not to damage the interior of the key.

Step-By-Step Guide: Hyundai Key Fob Battery Replacement

  1. With the key fob open, remove the old battery. Remember how the battery is positioned in the key fob before removing it.
  2. Check to see the kind of battery needed. Most key fobs require a CR2032 battery. These affordable batteries are easy to find at department stores and auto stores around the Lawrenceville area or online.
  3. Place your new battery into your key fob in the same position as the old battery. If placed incorrectly, the battery may discharge, causing the key to fail.
  4. Reinstall the key fob battery cover.
  5. Re-insert the mechanical key by pushing the key in until a clicking sound is heard.

These steps will be the same for both the remote key and the available Hyundai Smart Key, ensuring you’re covered regardless of which Hyundai key fob you own.
