1. A door lock comprising:
a latch device including a latch movable between a latching position and an unlatching position;
an inner operating device mounted to a side of the latch device and is configured to move the latch between the latching position and the unlatching position, wherein the inner operating device includes an inner escutcheon having a maintenance hole;
an outer operating device mounted to another side of the latch device and is configured to move the latch between the latching position and the unlatching position, wherein the outer operating device includes an outer escutcheon having a mounting area, and wherein the mounting area includes a socket aligned with the maintenance hole;
a main board fixed in the inner escutcheon, wherein the main board is configured to control the outer operating device to or not to move the latch between the latching position and the unlatching position;
a fastener rotatably coupled with the socket; and
an input interface module removably mounted in the mounting area and electrically connectable with the main board, wherein the input interface module is configured to permit input of an unlocking identification information or an unlocking command by a physical or wireless measure, wherein the input interface module includes a connecting member, wherein when the maintenance hole is revealed, the fastener is rotatable to tighten or loosen the connecting member of the input interface module, wherein when the connecting member is tightened by the fastener, the input interface module is secured in the mounting area, and wherein when the fastener is disengaged from the connecting member, the input interface module is removable from the outer escutcheon,
wherein the input interface module further includes:
a box including a fixing hole and a compartment spaced from the fixing hole, wherein the box further includes a coupling portion at a bottom thereof, wherein the outer escutcheon further includes a vertical wall and a bottom wall contiguous to the vertical wall and the mounting area, wherein the outer escutcheon further includes a slot extending from the vertical wall and an insertion groove extending from the bottom wall, wherein the coupling portion of the box is removably coupled with the insertion groove, and wherein the connecting member is coupled with the fixing hole;
a circuit board securely disposed in the box, wherein the circuit board includes an outer connecting seat received in the compartment; and
