A key fob for housing at least one electrical component for wireless communication with a vehicular system includes a main body having at least one actuator button. The actuator button is operable to control an electrical component for wireless communication with a vehicular system. The main body includes a first detent mechanism. The key fob further includes a cap moveably connected to the main body. The cap is moveable between a closed position and an open position such that in the closed position the cap at least partially covers the actuator button and such that in the open position the cap at least partially exposes the actuator button. The cap includes a second detent mechanism. The second detent mechanism is operable to cooperate with the first detent mechanism to lock the cap relative to the main body in one of the closed position and the open position.
