Many Ford vehicles have convenient aftermarket features such as remote start. When it's enabled in your vehicle, you can start the engine from up to 60 feet away. Programming the key fob that controls it is a cinch.
Sit in the driver's seat. Leave the driver's side door open.
Insert the key and turn it to the "On" position. Do not start the engine.
Press and hold the "Programming/Override" button for approximately 15 seconds or until the horn sounds three times; release the button.
Press any button on the fob. The horn sounds once to indicate that the fob has been programmed successfully.
