Abstract: The present invention relates to a motor vehicle that is equipped with an electrical door closing mechanism, a radio-based signal receiver and a control unit, wherein the door closing mechanism can be actuated after receiving and verifying an access authorization code by electrical signals that are generated by a control unit. The motor vehicle possesses an electrical charging apparatus accessible from the outside so that a signal generator that is provided to generate the access code can be charged from the electrical system of the motor vehicle in the event of an insufficient charge. Furthermore, the invention describes a method for charging a signal generator that can be executed using the device according to the invention.

Abstract: The invention relates to a method for operating an anti-theft system of a motor vehicle, comprising a communication system for near field communication and a storage device within a transmission and reception zone of the communication system. The mobile terminal is deposited in a control area in the interior compartment of the motor vehicle, the control area being located outside the transmission and reception zone. The deposited mobile terminal is connected to the communication system by a connecting device, which may, e.g., take the form of a cable, and a wired data communication connection is established. A control unit detects whether the data communication connection has been established with the mobile terminal by the connecting device and detects whether the mobile terminal is authorised to operate the anti-theft system, and depending on whether the authorisation has been detected, activates and/or deactivates a function of the anti-theft system.
