2003 F-350 how do I UNprogram the original key fobs that came with the truck. If I start the program routine and use no key fobs will that clear the codes from the truck?
The truck now has an alarm and remote start that is controlled by it's own fobs. I reprogramed one of the original truck fobs to work with another Ford car (which works fine). However if I attempt to open the car, it also opens the truck which sets the alarm off in the truck, because someone moved the locks. So I need to somehow get the truck to forget about the old key fobs.
