Abstract

The invention relates to a method for operating a motor vehicle (10) by means of a fob device (22) for authorizing a user of the motor vehicle (10) to unlock at least one function. The key device has an identification code which unambiguously indicates the identity of the key device and an authorization data set for at least A function is described. The authorization data set (43) and the identification code (41) are received by the control device (12) of the motor vehicle (10) from the key device (22) (S6). In addition, the received authorization data set (43) and the received identification Whether the code (41) corresponds to a predetermined combination (S8). At least one function is triggered corresponding to said predetermined combination (S9). The invention also relates to a portable key device (22).

Description

Technical field [0001] The invention relates to a method for operating at least one function of a motor vehicle, wherein the user of the motor vehicle authorizes the use of the at least one function by means of a portable key device. The invention also relates to such a key device. Background technique [0002] In many countries, for example, valet parking or refueling services or car wash services during visits to restaurants or hotels are a matter of course. The valet parking key specially set for this can start the vehicle, but for example cannot open the glove box. In modern vehicles, the following necessity is gradually eliminated: the traditional key must be inserted into the ignition switch to activate the vehicle. The start key combined with the near field transmitter in the key assumes this function. In service work, for example, in a car wash operation in the United States, the vehicle and the key are usually handed over to the employee and retrieved after finishing ...
