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.

A calibration system for induction keys includes a signal source and a computing device. The signal source is configured to generate a low frequency (LF) signal and a magnetic field signal at intervals. The computing device is configured to receive the magnetic field signal transmitted by an induction key when the induction key senses the LF signal. The computing device is configured to obtain a magnetic field strength from the magnetic field signal, and then comparing the magnetic field strength with a pre-stored standard strength of the magnetic field to achieve an offset. The computing device sends the offset value to the induction key and enables the induction key to get a calibrated strength value of the magnetic field according to the offset value. This disclosure further provided an induction key and a calibration method.

Disclosed is a proximity switch provided with an actuator unit and a sensor unit. The sensor unit is provided with an antenna coil, a transmitting circuit which transmits electromagnetic waves at a constant frequency to the antenna coil, a receiving circuit which detects external signals received by means of the antenna coil, and control circuits. The actuator unit is provided with an antenna coil, a power supply circuit which rectifies an electromotive force generated in the antenna coil, and a signal processing circuit which receives power supply from the power supply circuit, performs frequency-dividing to the signals received by means of the antenna coil, and transmits the signals from the antenna coil after the frequency-dividing. The control circuit of the sensor unit has memory for registering the frequency of the signals transmitted from the actuator unit. The control circuit determines whether the actuator unit is in proximity to the sensor unit or not by checking the received signals detected by means of the receiving circuit with the operations of the transmitting circuit and the frequency registered in the memory.
