How to Open a Hyundai Key Fob & Replace Battery

Keep in mind that replacing the battery can depend on the year and model of your Hyundai:

Step-by-Step Guide: How to Open a Hyundai Key Fob

• You can remove the metal key by pressing and holding the metal tab or button. 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. The case should pop right open.
• If you drive an older Hyundai model, there’s a small notch along the side of the key fob. You can either use a flat blade screwdriver or a coin to carefully pry open the key fob at the notch.

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

1. With the key fob open, gently lift the circuit board to see the battery. Remember how the battery is positioned in the key fob before removing it since this is how you will place the new battery into the key fob.
2. Check to see the kind of battery needed. Most key fobs require a CR2032 battery. These are affordable batteries that are easy to find at department stores and auto stores around the Macon area or online.
3. Place your new battery into your key fob. The battery needs to make contact with all of the connections.
4. If you removed a metal key, remember to replace it when your Hyundai key fob is snapped back together.

Once the battery is replaced, your fob must be programmed.

How to Program a Hyundai Key Fob

This is how to program a Hyundai 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.

The above method is only for key fobs previously programmed for your Hyundai. If you get a brand new key fob, our service center near Gray can take care of programming it.
