A door lock includes a casing mounted in a bare of a door. The casing includes inner and outer coupling seats to which inner and outer mounting plates are mounted respectively. The outer coupling plate includes two diametrically opposed slots located outside the bore of the door. The inner mounting plate includes a plurality of pairs of diametrically opposed holes. The inner mounting plate is rotatable relative to the inner coupling seat to a position in which one of the plurality of pairs of holes is aligned with the slots. Two mounting posts are extended through the slots and through two through-holes in the door. Each mounting post is slideably received in one of the slots, allowing the mounting posts to move toward or away from each other until a spacing between the mounting posts is equal to that between the two through-holes of the door.
