providing a plurality of short-range transceiver units;
ascertaining first position data of the first identification key carried by a user while the user moves outside of the motor vehicle as soon as the first identification key enters a reception range of a first one of the short-range transceiver units, the first short-range transceiver unit ascertaining the first position data of the first identification key;
transmitting the first position data via a first far-field transceiver unit not disposed in the first identification key;
ascertaining second position data of the first identification key, as soon as the first identification key enters the reception range of at least one further short-range transceiver unit among the short-range transceiver units, the further short-range transceiver unit ascertaining the second position data of the first identification key;
transmitting the second position data via a second far-field transceiver unit;
receiving at least the first and second position data by a third far-field transceiver unit;
ascertaining at least one movement vector for the first identification key from at least the first and second position data;
checking whether the movement vector meets at least one predefinable activation criterion for activating the preconditioning of the at least one component of the motor vehicle; and
when the checking is affirmative, activating the preconditioning of the at least one component of the motor vehicle.
