Okay let me first say I am not getting a new key programmed I am replacing the whole lock cylinder. I need to reprogram the whole set up to the truck and cant find a thread about it. Its an 03 Excursion eddie bauer edition 4wd with THE 6.0L production date 3/03. No mods at all. completely stock...

Godiag T300+ As we known, Ford keys use advanced technology to start the engine and operate the power door locks. If I have had to replace my car's battery or my key fob battery, does I need to reprogram my keys???
