An electronic door lock is provided. An outer housing (1) of the electronic door lock is fixed at an outer side of a door plate. An unlocking message acquisition device is disposed at the outer housing (1). An exterior handle (2) is pin-jointed to the outer housing (1). An inner housing (3) is fixed at an inner side of the door plate. An interior handle (4) is pin-jointed to the inner housing (3). A mechanical lock (5) is fixed inside the door plate. A main bolt (6) and a spindle hole (7) linked thereto are disposed in the mechanical lock (5). A square spindle (8) drives, via the spindle hole (7) of the mechanical lock (5), the main bolt (6). A transmission shaft (9) transmits, to the inner housing (3), a movement of the exterior handle (2), and is disposed in the electronic door lock. A clutch base (10) is disposed in the inner housing (3). The transmission shaft (9) is linked via an internal transmission mechanism to the clutch base (10). A pushing pin (15) is disposed in the interior handle (4). A pushing pin spring (16) forces the pushing pin (15) to eject from a square spindle base (12). When the pushing pin (15) is inserted into the square spindle base (12), the interior handle (4) drives the square spindle base (12) to lock or unlock the door. When the pushing pin (15) is ejected from the square spindle base (12), the interior handle (4) disengages from the square spindle base (12).
