Abstract: A method and system of minimizing sticky keys in an electronic device having a body, circuitry, and a plurality of keypads is disclosed. The method and system comprise providing a protectant coating; and applying the protectant coating on surfaces of both the keypad and also the body to prevent sticking between the mating surfaces. A system and method is added in accordance with the present invention utilizing a protectant on critical surfaces which serves to prevent the residual buildup of contaminants following spills. In so doing the sticky key problem associated with the contaminated buildup is substantially eliminated.
