Abstract
A device for locking and unlocking a door of an object, particularly of a motor vehicle, includes a transmitter unit disposed on the object and a transponder assigned to a user. Safety is increased because, in response to alignment of the transmission lobe with the interior of the object, the range of the field of the transmission lobe formed by the transmitter unit or of the signals emmitted by the transponder can be reduced or disturbed by a switching device, so that a transponder located in the passenger area of the interior cannot be queried.
