A door lock/unlock system for a vehicle, comprising: a door lock state detector detecting whether a door of the vehicle is put in a lock state; a door open state detector detecting whether the door is open; a door lock mechanism through which the door is locked and unlocked; and a controller connected to the door lock state detector, the door open state detector and the lock mechanism, the controller being arranged, to compare a first lock/unlock state detected by the door lock state detector during the door open state with a second lock/unlock state detected by the door lock state detector at a moment when an open/close state is changed from an open state to a closed state, to maintain the state of the door lock mechanism when the first lock/unlock state equals to the second lock/unlock state, and to set the state of the door lock mechanism at the first lock/unlock state when the first lock/unlock state does not equal to the second lock/unlock state.
