Method for actuating a function of a vehicle from a large distance

摘要

A method for activating a function of a vehicle, which is associated with a key which wirelessly interchanges data with the vehicle, is carried out with the aid of a telecommunications device which is different from the key. However, the telecommunications device attempts to communicate with the key in order to make the method safe. During communication with the key, an item of information is obtained and is compared with an item of comparative information.
