Programming a Hyundai Sonata key fob is a straightforward process often required after battery replacement. This guide provides a step-by-step walkthrough to help you successfully program your key fob and regain access to your vehicle’s keyless entry features.
Programming Your Hyundai Sonata Key Fob
Before starting, ensure all car doors are closed. Next, insert your key into the ignition and turn it to the “ACC” or accessory position. Locate the “Unlock” or “Open” button on your key fob. Press and hold this button for several seconds. Successful programming is indicated by flashing lights on your car, usually the hazard lights.

Replacing the Key Fob Battery
A dead key fob battery is the most common reason for reprogramming. Accessing the battery compartment varies slightly between Hyundai Sonata models and years. Generally, look for a small notch or indentation on the key fob’s side. Use a small flathead screwdriver to gently pry open the fob casing. Inside, you’ll find a circuit board. Carefully lift it to expose the battery, typically a CR2032. If you need a replacement, your local Hyundai dealership can assist you.
Key Fob Programming Considerations
This programming procedure works only for previously programmed key fobs. For brand new Hyundai Sonatas, or if you’ve lost all your programmed keys, you’ll need to visit a Hyundai dealership or authorized service center. Their technicians have specialized equipment to program new key fobs to your vehicle.
Need Help with Your Hyundai Sonata Key Fob?
While programming your Hyundai Sonata key fob is generally simple, don’t hesitate to contact a professional if you encounter any difficulties. Your local Hyundai dealership’s service department can provide expert assistance, answer your questions, and ensure your key fob is properly programmed. They can also assist with battery replacement and other key fob related services.
