The present invention relates to a door lock drive assembly, which selectively couples an inner door handle shaft to an outer door handle shaft in accordance with an identification signal or a key motion, and which maintains a tightly coupled state even when a high level of torque is transmitted to the door handle shafts. The door lock drive assembly according to the present invention includes: a shaft-connecting unit including a pressing member which selectively connects the first door handle shaft to the second door handle shaft such that the shafts are coupled together or separated from one another; a slide unit, including a pressing unit which is movable upward and downward in order to press the pressing member; and a mechanical driving unit including a keyway, into which a key is inserted and turned so as to move the pressing unit of the slide unit upward and downward. |
