An electronic key (30) for a vehicle (10) comprises a motion sensor (31) configured to detect a movement of the electronic key (30), a processing unit (32), and a transceiver unit (33) configured to transmit signals to and receive signals from the vehicle (10). Upon occurrence of a triggering event, the processing unit (32) is configured to, if it is detected by the motion sensor (31) that the electronic key (30) is not moving, and if the electronic key (30) is detected to be outside the vehicle (10), switch the transceiver unit (33) from an enabled state to a disabled state such that no signals may be received from the vehicle (10). The processing unit (32) is further configured to, if it is detected by the motion sensor (31) that the electronic key (30) is not moving, and if the electronic key (30) at the same time is detected to be inside the vehicle (10), keep the transceiver unit (33) in the enabled state.
