Abstract
A method for wirelessly accessing a vehicle including the steps of: exchanging data between a UID-transponder and the vehicle to verify authorization of the UID-transponder, triangulating a location of UID-transponder relative to the vehicle using at least three first antennas being positioned at three different first positions of the vehicle and providing access to the vehicle under the first authorization condition that the UID-transponder is identified as an authorized UID-transponder and if the location meets a second authorization condition as well, to recognize a relay attack.
