This problem is caused by a bad Driver Door Module. It is available at your Ford dealer for about $300.00. It comes with a code to reprogram your keyless entry system. If you can remove your driver door trim panel you can easily do the job yourself. I have heard a quote of $550.00 if Ford does the job but that could vary depending on your location. You could buy used for around $100.00 and Ford will reprogram it, after it is installed, for $125.00.
