Abstract
A wireless key () for unlocking a vehicle and/or for enabling a function of the vehicle. The wireless key () has a sensor () for motion detection, an evaluation unit (), and a transceiver () which is designed to signal its availability as a connection partner and to wirelessly transmit data to a connection partner and/or to receive data from the connection partner. The transceiver () has at least one operating mode (A, B) and at least one sleep mode (C, D) where an energy requirement of the transceiver () is lower than in the at least one operating mode (A, B). The evaluation unit () is designed to switch the transceiver from the operating mode (A, B) to the sleep mode (C, D) if no movement is detected by the sensor () within a predetermined interval and to switch the transceiver () from the sleep mode (C, D) to the operating mode (A, B) if a movement is detected by the sensor ().
