System allowing service provider to selectively open vehicle

A system for selectively opening a vehicle, comprises a first communication module for establishing a communication link to a communication terminal of a service provider who obtains authorization data via a communication network, a first identification routine for unambiguously identifying the service provider, a second communication module for establishing, via a wireless communication network, a communication link to a communication device of a control unit of the access arrangement on a vehicle, a second identification routine allowing the access arrangement to unambiguously identify the system, a third communication module for receiving update request data from the driver, and an update routine for updating authorization data in a memory of the system. When valid authorization data has been provided, the control unit, using the second communication module for establishing, via a wireless communication network, a communication link to a communication device of the control units of the access arrangement off a vehicle, receives a profiled control signal via the communication link, said profiled control signal causing the vehicle to be selectively opened via the control unit.
