Replacing the battery in your Hyundai key fob is a common task, and often, it requires reprogramming the key fob to work with your vehicle again. The good news is that Hyundai Program Key Fob procedures are generally simple enough to handle yourself at home, allowing you to regain access to all your remote system’s essential features without a trip to the dealership for basic reprogramming.
To begin the Hyundai program key fob process, start inside your Hyundai, ensuring all doors are completely closed. Next, you’ll need your physical key to access the accessory function. Insert your Hyundai key into the ignition switch. Turn the key to the “ACC” (Accessory) position. This is typically the first position you encounter when turning the key clockwise, before actually starting the engine. You should hear a click and some of your car’s electronics may turn on.
Once in the ACC position, locate the “Unlock” or sometimes labeled “Open” button on your Hyundai key fob. Press and hold this button down firmly for several seconds. Keep holding the button while you observe your vehicle for a signal confirming successful programming. Typically, you will see a light flash somewhere on your car. This light flash is your confirmation that the Hyundai program key fob sequence has been successful and your key fob should now be recognized by your Hyundai’s system.

The most frequent reason you need to program Hyundai key fob is after replacing a dead battery. Opening the key fob to access the battery is usually straightforward. Most Hyundai key fobs have a small indentation or notch along the side. You can typically use a small flathead screwdriver or even a fingernail to gently pry it open. Once open, you’ll see a circuit board and the battery. The standard replacement battery for most Hyundai key fobs is a CR2032 battery. When replacing the battery, ensure you are using the correct type and that it is inserted with the correct polarity to avoid any issues.
Keep in mind that these DIY Hyundai program key fob instructions are generally for reprogramming a key fob that was already paired with your Hyundai, especially after a battery change. If you’ve purchased a new Hyundai, are adding a new key fob, or are dealing with a completely new key fob or a system malfunction, you’ll likely need to visit a Hyundai service center. Expert technicians have specialized tools and diagnostic equipment to program new key fobs, integrate them into your car’s system, and diagnose any more complex underlying issues that might be preventing your key fob from programming correctly.
