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.

Apparatus, key remote, and method for controlling operating conditions of a key module

A method for assessing a reliability of a determination of the relative position between a device for accessing a vehicle and the vehicle including transmitting a first radio signal from a first antenna of the vehicle; transmitting a second radio signal from a second antenna of the vehicle; receiving the first radio signal at the device and determining a first signal intensity; receiving the second radio signal at the device and determining a second signal intensity; determining, at the device or the vehicle, a relative position of the device and/or the vehicle and/or signal directions from which the radio signals have arrived at the device, based on the first signal intensity and the second signal intensity; determining a compatibility of the determined relative position and/or the signal directions with an arrangement of the first antenna and the second antenna at the vehicle to assess the reliability of relative position determination.
