Replacing the battery in your Hyundai key fob is a common part of car maintenance. However, after a battery change, you might find your key fob isn’t communicating with your vehicle anymore. This is because changing the battery can sometimes require you to reprogram your Hyundai key fob to regain access to features like remote locking and unlocking. Luckily, reprogramming your Hyundai key fob is often a straightforward process you can do yourself.
Step-by-Step Guide to Reprogramming Your Hyundai Key Fob
If you’re looking to restore the functionality of your Hyundai keyless remote after a battery replacement, follow these simple steps. This method generally works for previously programmed key fobs.
-
Enter Your Hyundai and Close All Doors: Begin by getting inside your Hyundai vehicle and ensuring that all doors are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Turn the Ignition to “ACC”: Insert your Hyundai key into the ignition. Turn the key to the “ACC” (accessory) position. This is typically the first position before starting the engine. You should see the dashboard lights illuminate.
-
Press and Hold the “Unlock” or “Open” Button: Locate the “unlock” or “open” button on your Hyundai key fob. Press and hold this button down for several seconds. Keep holding it until you observe the next step’s indicator.
-
Check for Confirmation: When the reprogramming process is successfully completed, your Hyundai will usually provide a visual confirmation. This is often indicated by the car’s lights flashing. This flashing light signals that your key fob is now recognized and paired with your vehicle again.

Understanding Key Fob Battery Replacement
Often, the need to reprogram your Hyundai key fob arises after replacing a dead battery. Accessing the battery compartment is usually quite simple. The design of the key fob can vary slightly depending on your Hyundai model and year.
Most Hyundai key fobs are designed with a small indentation or notch along the side of the casing. You can typically use a small flathead screwdriver or even a coin to gently pry open the fob at this point. Once opened, you’ll see a circuit board. Carefully lift the circuit board to reveal the battery underneath.
The battery will have a number printed on it, indicating the battery type required for your Hyundai key fob. The most common battery type is the CR2032. When replacing the battery, ensure you use the correct type for optimal performance. If you’re unsure about the correct battery, your local dealership’s parts department can assist you in finding the right replacement.
Important Considerations and Tips
Keep in mind that these reprogramming instructions are generally for key fobs that have been previously programmed to a Hyundai vehicle. If you have purchased a brand new Hyundai or are dealing with a completely new, unprogrammed key fob, this procedure might not work.
In cases where you have a new Hyundai or are facing difficulties reprogramming an existing key fob, it’s best to visit a certified Hyundai service center. Expert technicians at the service center have specialized tools and diagnostic equipment to program new key fobs to your vehicle. They can also diagnose and resolve any underlying issues if the reprogramming process is unsuccessful.
If you need any assistance with your Hyundai key fob reprogramming or any other car-related service, don’t hesitate to contact your local Hyundai dealership for professional support and guidance. They are equipped to handle all your Hyundai service needs, ensuring your key fob and vehicle systems are working correctly.
