Abstract: A door lock system includes a first circuit performing a first communication to request a response for determining availability of unlocking a door, a second circuit performing a second communication for determining availability of unlocking the door and transmitting a reception result of the second communication to an outside of the door lock system, and a control circuit controlling operations of the first circuit and the second circuit. The control circuit stops one of the first communication and the second communication from being performed in a case where the other one of the first communication and the second communication is performed.
