The key RF fob may further include a plurality of wedge-shaped buttons such as four wedge-shaped buttons. The key RF fob may include a first cross member and a second cross member wherein the first cross member and the second cross member intersect to form four apertures each of the four wedge-shaped buttons disposed within one of the apertures.
