The invention discloses an asynchronous door knife with a car door lock. When a second unlocking blade device receives pushing force from the door opening direction, the second unlocking blade device drives a first unlocking blade to move horizontally through a rope under the guide effect of a horizontal guide mechanism; the movement of the first unlocking blade drives a rotating hook of a rotating lock hook component to rotate in the unlocking direction, so as to enable the rotating hook of the rotating lock hook component to be unhooked from a fixed hook to unlock the rotating lock hook component; and meanwhile, the rotation of the rotating hook drives a driving door switch trigger to rotate, so as to enable the electrical contact of the pickgurard driving door switch to be disconnected. The asynchronous door knife has the functions of opening the car door lock and switching a door in-place switch; a landing door device is not to be equipped with a landing door pickgurard and other additional mechanism for unlocking of the car door lock, and during emergency rescue of a leveling layer, the car door lock is unlocked by opening a landing door. The invention further discloses an elevator door motor with the asynchronous door knife with the car door lock and a car door system adopting the elevator door motor.
