The main chauffeur behind the appeal of car key shell repair is monetary. Dealers rarely offer "shells only." Rather, they sell the entire unit, which includes a new PCB and transponder. This requires the car to be present for specialized programs, adding labor costs to the costly hardware.

By contrast, a shell repair kit includes just the plastic casing and sometimes a brand-new un-cut blade.
