PURPOSE: A door lock apparatus is provided to stably operate although the failure of the electronic device is generated, thereby making the reliability of the door lock apparatus double. CONSTITUTION: A door lock apparatus includes a latch unit(20), a latch stopper unit(30), a stopper push unit(40), a lever unit(60), a supporting unit(50) and a lock control unit. The latch unit(20) pivotally rotates to an original position by an elastic force when an external force is not applied. The latch stopper unit(30) is hooked on the latch unit(20) or inserted into the latch unit(20). The stopper push unit(40) protrudes to outside through the push hole formed on the body portion with elastically connecting the latch stopper unit(30). The lever unit(60) operates the latch unit(20) and the latch stopper unit(30) with pivotally connecting to the inside and outside rods of the inside and outside handle. The supporting unit(50) supports the lever unit(20). And, the lock control unit locks or unlocks the door lock apparatus not so as to move the latch stopper unit(30) or combine the supporting member with the latch unit(20).
