The present invention relates to a digital door lock installed in a first door and a second door to open or close at least one of the first door and the second door. The digital door lock comprises: a first main body unit which is installed on one surface of the first door; a second main body unit which is installed in the second door to form a receiving space; a locking unit which is installed in the first main body unit and of which a portion is received in the receiving space to close the first door and the second door and removed from the receiving space to open at least one of the first door and the second door; a driving unit which is installed in the first main body unit and moves the locking unit to receive the portion of the locking unit in the receiving space or remove the portion of the locking unit from the receiving space; a detection unit which is in contact with one surface of the first door to detect a signal transmitted to one surface of the first door through the other surface of the first door; and a control unit which is electrically connected to the detection unit and the driving unit to control the driving unit when the detection unit detects the signal. Therefore, the digital door lock of the present invention can move the locking unit for closing or opening the first door and the second door by using the signal transmitted to one surface of the first door through the other surface of the first door, thereby having no need for an outer unit installed outside the first door. |
