To provide motor vehicle access, a connection is set up between an ID signal generator assigned to the vehicle and a wireless communication device. A first identification code, stored in the ID signal generator, is transmitted to the communication device. A connection is set up between the communication device and a service provider via a public communication network. The identification code is sent together with a second identification code which identifies the wireless communication device. A multi-part authorization message is generated by the service provider. Parts of the authorization message are sent to the communication device and parts transmitted to a control device in the vehicle. Access authorization of the communication device is checked on the basis of the part of the authorization message from the vehicle and the part from the communication device, via a connection between the communication device and the control device of the vehicle.
