A door lock for a door panel includes a coupler and a door handle. The coupler is mounted rotatably on the door panel and is capable of driving rotation of an operating spindle between first and second angular positions for moving a latch bolt between latching and unlatching positions, respectively. The door handle includes a handle sleeve that is sleeved fittingly and removably on the coupler, and a lever that extends outwardly and radially from the handle sleeve. The lever extends sidewardly when the operating spindle is at the first angular position, and is operable so as to rotate the door handle downwardly such that the coupler drives rotation of the operating spindle from the first angular position to the second angular position.
