can you be specific about the problem?is it about the keys(there is a chip imbedded in the black plastic) or the remotes?i work as a ford dealer tech.from my experience its best not to wire an aftermarkit alarm on top of the ford system.if the ignition lock cylinder gets pulled with a slide hammer it wont start.the dealer has to program the keys into the car with a scan tool.my girlfriend's car has a extra key underneath the back seat so if she loses the keys she can have aaa slim jim it and still drive it.
