How do you program the keyless entry remote on a 2000 Ford Excursion?

To program the keyless entry remote for a 2000 Ford Excursion, first, sit in the driver's seat and close all doors. Turn the ignition to the "On" position (without starting the engine) and then back to "Off" eight times within 10 seconds. The door locks will cycle to indicate that the vehicle is in programming mode. Press any button on the remote to be programmed, and the locks will cycle again to confirm successful programming. Repeat for additional remotes, and then turn the ignition to "On" to exit programming mode.
