How do you reset keyles entry on a 2000 ford excursion?

To reset the keyless entry on a 2000 Ford Excursion, first, ensure that you have the factory key fob. Insert the key into the ignition and turn it to the "On" position without starting the engine. Press the "Unlock" button on the driver's side door panel and hold it while you turn the ignition off and then back to "On" three times. Release the "Unlock" button, and the system should beep to confirm the reset. You can then program your key fob by pressing any button to complete the process.
