Understanding the Process

The process of programming a new key fob for your 2015 Hyundai Sonata involves synchronizing the key fob’s electronic code with your vehicle’s computer system. This allows the key fob to communicate with the car and perform functions like unlocking the doors, starting the engine, and activating the alarm.

Gather Your Materials

Before you begin the programming process, make sure you have the following:

• New key fob: This should be a genuine Hyundai key fob specifically designed for the 2015 Sonata.
• Existing key fob: You will need a working key fob to initiate the programming sequence.
• Vehicle owner’s manual: The owner’s manual provides detailed instructions specific to your vehicle model.

The Programming Steps

Step 1: Prepare the Vehicle

• Unlock the doors: Use your existing key fob to unlock all doors of your Sonata.
• Insert the key: Insert your existing key into the ignition and turn it to the “ON” position without starting the engine.

Step 2: Enter Programming Mode

• Locate the programming button: The programming button is typically located within the driver’s side door panel. It might be concealed behind a small cover or labeled with a key symbol.
• Press and hold: Press and hold the programming button for at least 10 seconds. You should hear a chime or see a flashing indicator light on the dashboard, signifying that the vehicle is in programming mode.

Step 3: Program the New Key Fob

• Insert the new key fob: While the vehicle is in programming mode, insert the new key fob into the ignition.
• Turn the key: Turn the key to the “ON” position without starting the engine. You should hear a chime or see a flashing indicator light on the dashboard, confirming that the new key fob has been recognized.
• Remove the key: Remove the key fob from the ignition.
