To replace the driver side mirror on a 2003 Ford Focus you will need a socket and a Philips head screwdriver. Loosen the driver side door panel so that you can reach inside to unplug the wiring harness, and then remove the bolt and screw to remove the mirror. Put the new mirror in place and reattach everything you just removed.
