• To remove the metal key, press and hold the metal tab or button. You can then use the metal key to open up the back cover on your key fob by inserting the key into the tiny opening and turning it in either direction. Once you do this, the case should pop open. 
• Those who drive an older Hyundai model should notice a small notch on the side of the key fob. WIth a flat blade screwdriver or a coin, carefully pry open the key fob at the notch. 

How to Replace a Hyundai Key Fob Battery: Step-by-Step Guide

1. With the key fob open, carefully lift the circuit board to locate the battery. Remember how the battery is positioned in the key fob before taking it out since this is how you’ll place the new battery into the key fob.
2. Check and see the type of battery that’s needed – most key fobs require a CR2032 battery. These batteries are affordable and easy to find at local auto parts stores around the Newville area.
3. Place your new battery into your key fob. Make sure that the battery makes contact with all of the connections.
4. If the metal key was removed, remember to replace it when your Hyundai key fob is snapped back together.

Now that you have your new battery in the key fob, your next step is learning how to program your Hyundai key fob. 

How to Program a Hyundai Key Fob

Follow these steps below to program your key fob: 

1. Get inside your Hyundai and close the doors.
2. Using your key, turn your Hyundai to the “ACC” (accessory) position on your ignition.
3. Hold the “open” or “unlock” button on the key fob until your car lights flashes.

You’re all set! Now that your key fob is programmed, it’s best to test your key to make sure that it’s working properly. If it’s not, reopen the case and check that the battery is in there correctly and the connections are touching. Then, reprogram your Hyundai key fob. 

Keep in mind that the above only works on key fobs that were previously programmed for your Hyundai. If you purchased a new key fob, please visit our service center to have it programmed.
