Abstract
The invention relates to a device for checking the closed state of a door mounted on an object (1), especially on a motor vehicle, by using an electronic key (2). The electronic key (2) and the object (1) are each fitted with intercommunicating transmitter/receiver units (3, 4 or 13, 14). The closed state of the door (1) is determined via a closure detecting sensor (8) on the door (7) and indicated via optical displays (10 or 16) on the outside of the object (1) and/or on the electronic key (2).
