Abstract

An apparatus, a key partner, methods and computer programs for a key module of a vehicle and a vehicle. The apparatus for the key module includes a communication interface for radio communication with a key partner of the vehicle, a motion sensor, and a control module for controlling an operating state from operating states of the key module based on the information about the motion of the key module. The operating states include at least a first operating state, a pre-shutdown operating state and a shutdown state. The control module activates the first operating state if the motion of the key module is above a motion limit value and activates the pre-shutdown operating state if the motion of the key module is below the motion limit value over a period of time.
