A key fob assembly comprises an electronic circuit comprising a substrate carrying a plurality of switching elements and a display element. A rear casing member having a first outer rim and receives the electronic circuit. A front casing member has a second outer rim, a plurality of button apertures, and a display window. The button apertures are substantially aligned with the plurality of switching elements and the display window is substantially aligned with the display element. A lens is contained within the display window providing a protective layer over the display element. An elastomeric seal member is provided having an outer periphery captured between the first and second outer rims and having a display aperture defined by an edge wherein the edge is captured between the display element and at least one of the front casing member and the lens. The elastomeric seal member includes a plurality of pedestals aligned with respective ones of the button apertures. A plurality of substantially rigid button caps are each cohered to a respective one of the pedestals and project into a respective one of the button apertures, whereby a button cap can be depressed toward the substrate to actuate a respective one of the switching elements.
