Abstract
A vehicle locking system has a locking unit for a movable vehicle part (particularly a trunk lid) which can be moved between an opened and a locked position and which, in the opened position, provides access to an adjoining vehicle interior area and blocks such access in the locked position. When an authentication element is used which can be carried along on the user side, the locking unit, is reversible between an unlocked state, in which it releases the opening of the movable vehicle part, and a locked state in which it prevents the opening of the movable vehicle part. Authentication element detection devices determine whether an authentication element is situated in the vehicle interior area, and, if so, control the locking unit into its unlocked condition and/or generate a corresponding indicating signal.
