Abstract
A remote key fob for a vehicle, includes a communications and control device, at least one transmit/receive device and a microcontroller. At least one control surface is arranged on an outer shell of a housing of the remote key fob and is coupled to the communications and control device. A printed circuit board held in the housing is placed beneath the control surface. The control surface is mechanically coupled to a metal detection section. Pressure actuation of the control surface from the outside results in a deformation or change of position of the detection section. A detection coil is located on the printed circuit board, wherein the detection coil is coupled to the communications and control device for forming an inductive proximity switch. The communications and control device determines an actuation of the control surface as a function of the inductivity or quality of the detection coil.
