How to Open a Hyundai Key Fob & Replace Battery

Before completing the Hyundai key fob battery replacement, it’s good to know how to open the Hyundai key fob itself. This simple task varies based on the model year of your vehicle.

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

• 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 open right up.
• If it’s an older Hyundai model, there’s a small notch along the side of the key fob. You can either use a coin or a flat blade screwdriver to 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, carefully lift the circuit board to locate the battery. Remember how the battery is positioned in the key fob before removing it since you will place the new battery into the key fob in the same position.
2. Check to see the type of battery needed – most key fobs require a CR2032 battery. These affordable batteries are easy to find at local auto and department stores around the Milan area or online.
3. Put the new battery into the 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.

Next is learning how to program your Hyundai key fob. 

How to Program a Hyundai Key Fob

Follow these steps to program your 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 flash.

Your key fob is programmed and ready to go! It’s recommended to test your key to make sure that it’s working correctly. If not, reopen the case and check that the battery was placed in there correctly and that the connections are touching. They reprogram your Hyundai key fob. If it’s still not working, a Hyundai key fob replacement is needed.

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