A digital door lock capable of easily releasing locked state is provided to minimize or prevent a damage of a human life by rapidly releasing a locked state of the door lock by an old or feeble person. A digital door lock capable of easily releasing locked state comprises a second driving gear(21), a locking body(22), a first manual gear(23), a second manual gear(24), a socket(25), a hand wheel(26), and a power transmission unit(27). The second driving gear is rotated by a motor(M) inside a housing(H). In the second driving gear, a circulation rod(21B) is downwardly protruded in an outer circumference of a rotation axis(21A). The locking body is combined with a formation capable of horizontally moving in a lower part of the second driving gear. In the locking body, the circulation rod is inserted in a center of a body(22A) in which a locking rod(22B) is protruded. The first manual gear is combined with a formation capable of rotating in a rotation axis of the second driving gear. The second manual gear is gear-combined in a left side and a right side of the first manual gear. The socket is combined with a formation capable of rotating in a rotation axis of the second manual gear. The hand wheel is exposed outside the housing.
