Programming Notes:

  • Verify the following prior to following these instructions:
    • Your vehicle is equipped with keyless entry, and
    • You have a key fob remote that is compatible with your vehicle.
  • Obtain ALL remote transmitters for this vehicle.
  • Keyless Entry Control Module Location:
    • Santa Fe / XG300 / XG350: Access alarm system control module located behind driver’s side fascia panel (Fig 100573)
    • Elantra / Sonata: Access central locking signal control module located behind fascia, center (Fig 100645)
  • Important: Please check to ensure you are able to find the Alarm Control Module and associated SET Switch mentioned in the instructions, otherwise you will not be able to perform the self-programming instructions and will be required to have an Automotive Locksmith program the key fob for you.
  • Alternative: If these instructions do not appear to work, try performing them again WITHOUT inserting the key into the ignition, as Steps 2 and 7 indicate, to see if this resolves the issue.

      Hello Vikar!

      Thanks for your question here. If you DO NOT have the SET/OFF switch, then your vehicle is NOT equipped with keyless entry. If you need to return an item feel free to reach out to our [email protected] email address for assistance.

      Thank you and take care,
      NorthCoast Support

        I also have a 2005 Hyundai Sonata I DEFINITELY has keyless entry because I have had two replaced already. Now am on #3 I purchased one on Amazon am retired Gasoline service station owner. Wasn’t going to replace it but, there were $19 and I figured after watching YouTube that I could do that you have myself.
        I took the dashboard apart took the module completely out of the vehicle. No on/off switch so now and forced to go to the dealership.
        They want $90 to do it. Do you happen to know anyone that will do it any cheaper?? $90 +$20 is a bit more than I plan to spend.
        Thank you Kenny G
