Follow these steps carefully to program your key fob:

Turn Ignition to ACC or ON: Insert your key into the ignition and turn it to the ACC (Accessory) or ON position. Do not start the engine.
Turn Off Radio: Make sure your radio is turned off.
Press and Hold DISP Button: Press and hold the DISP button on the radio for at least five seconds until “settings” is displayed on the radio screen.
Navigate to FOB PROG: Use the SEEK up or down arrows to scroll through the menu until you see “FOB PROG” on the display.
