A system for selectively opening a vehicle includes a first communication module for establishing a communication link to a service provider who obtains authorization data via a communication network, a first identification routine for unambiguously identifying the service provider, and a second communication module for establishing, via wireless communication, a communication link to a control unit of an access arrangement on a vehicle. A second identification routine allows the access arrangement to unambiguously identify the system. A third communication module receives update request data from the driver. An update routine updates authorization data in a memory of the system. When authorization is valid, the control unit receives a profiled control signal via the communication link, the profiled control signal causing the vehicle to be selectively opened via the control unit.
