Is your Hyundai Sonata key fob suddenly unresponsive? Perhaps you’ve just replaced the battery and now need to re-establish the connection with your vehicle. Reprogramming, or resetting, your Hyundai Sonata key fob is a common task that many owners can perform themselves. This guide provides a straightforward, step-by-step process to get your key fob working again, ensuring you regain access to all your remote system’s features.
Step-by-Step Guide to Resetting Your Hyundai Sonata Key Fob
Resetting your Hyundai Sonata key fob involves a simple procedure that you can typically complete in just a few minutes. Follow these steps carefully to reprogram your remote:
-
Enter Your Hyundai Sonata and Close All Doors: Begin by getting inside your Hyundai Sonata and ensuring that all doors are completely closed. This is crucial for the programming sequence to initiate correctly.
-
Turn the Ignition to the “ACC” Position: Insert your Hyundai Sonata key into the ignition. Turn the key to the “ACC” (Accessory) position. This position powers the car’s accessories without starting the engine and is necessary for initiating the key fob programming.
-
Press and Hold the “Unlock” or “Open” Button: Locate the “Unlock” or “Open” button on your Hyundai Sonata key fob. Press and hold this button down for several seconds. Keep holding the button until the next step is completed.
-
Observe the Car for Confirmation Signals: While holding the button, watch for a light to flash on your Hyundai Sonata. This flashing light is an indication that the key fob programming sequence has been successfully completed. The specific light and its location may vary slightly depending on your Sonata model year, but it’s usually the hazard lights or a light on the dashboard.
Once you observe the confirmation signal, release the button on your key fob. Your Hyundai Sonata key fob should now be reset and programmed to your vehicle. Test the key fob functions, such as locking, unlocking, and panic button, to ensure everything is working correctly.

Opening Your Hyundai Sonata Key Fob for Battery Replacement
Often, the need to reset your Hyundai Sonata key fob arises after replacing a dead battery. Accessing the battery compartment is usually straightforward. Hyundai Sonata key fobs are designed with a small notch or indentation along the side.
To open the key fob:
- Locate the Notch: Examine the edges of your key fob for a small notch or slot.
- Use a Tool to Pry Open: Insert a small flathead screwdriver or a similar thin tool into the notch. Gently twist or pry to separate the two halves of the key fob casing.
- Identify the Battery: Once open, you’ll see the internal circuit board and the battery. The battery is typically a small, round, disc-shaped battery.
- Note the Battery Type: Check the number printed on the battery. Hyundai Sonata key fobs commonly use a CR2032 battery. Knowing the correct battery number is crucial for purchasing the right replacement.
