- the update information set is transmitted as information for updating the dedicated application to the key device 2.
- the lock-side controller 12 controls the lock-side communication section 11 to intermittently drive the antenna, thereby transmitting the beacon signal.
- the key-side communication section 22 receives the beacon signal from the lock-side communication section 11.
- the communication area is a range within which the key device 2 can receive a radio signal from the electric lock control system 1 with intensity necessary for processes performed by the key device 2. That is, a range within which the key device 2 can receive, but cannot execute the process based on, a radio signal from the electric lock control system 1 is deemed outside of the communication area.
- the key device 2 When receiving the beacon signal, the key device 2 transmits the beacon response to the lock-side communication section 11.
- the lock-side communication section 11 receives the beacon response from the key device 2, and thereby, the authentication section 121 executes the authentication process.

- the lock-side controller 12 does not control the electric lock 3. That is, in this case, even if the user 6 operates the lock-side operation section 13, the lock-side controller 12 does not control the electric lock 3.
- step S10 When the user 6 carrying the key device 2 enters the communication area of the electric lock control system 1, the electric lock control system 1 starts communicating with the key device 2 (step S10).
- the authentication section 121 executes the authentication process (step S11).
- step S12: No When the authentication process is unsuccessfully performed (step S12: No), the lock-side controller 12 does not control the electric lock 3 as described above. In this case, even when the update information is stored in the key device 2, the lock-side communication section 11 does not receive the update information from the key device 2.
- step S12: Yes when the authentication process is successfully performed (step S12: Yes), the lock-side controller 12 controls the electric lock 3 to lock or unlock the opening and closing member 5 (step S13).
- the lock-side communication section 11 After controlling the electric lock 3 (i.e., after the authentication is successfully performed), the lock-side communication section 11 performs communication with the key device 2, thereby receiving the update information stored in the key device 2.
- the lock-side controller 12 updates the control program of the lock-side controller 12 based on the update information (step SI5).
- the lock-side controller 12 does not update the control program of the lock-side controller 12.
- the key device 2 communicates with the server 7 (step S20) regularly or at a timing at which the user 6 operates the key-side operation section 23. At this time, if there is an update information set which the key device 2 has not yet received (step S21: Yes), the key device 2 requests the server 7 to transmit the update information set. In response to the request from the key device 2, the server 7 transmits the update information set to the key device 2.
- the key-side communication section 22 receives the update information set from the server 7, the key-side controller 21 updates the program of the key-side controller 21 based on the update information of the program for use in key device 2 (step S22). Moreover, the key-side controller 21 causes the key-side storage section 24 to store the update information of the control program.
- the key device 2 acquires the update information of the control program included in the update information set (step S23). In contrast, if there is no update information set which the key device 2 has not yet received (step S21: No), the key-side controller 21 does not update the program of the key-side controller 21.
- step S24 When the user 6 carrying the key device 2 then enters the communication area of the electric lock control system 1, the key device 2 starts communicating with the electric lock control system 1 (step S24).
- the electric lock control system 1 executes the authentication process, but if the authentication process is unsuccessfully performed (step S25: No), the electric lock 3 is not controlled, and the opening and closing member 5 is neither locked nor unlocked. In this case, even when the update information is stored in the key device 2, the key device 2 does not transmit the update information to the electric lock control system 1.
- step S25: Yes When the authentication process is successfully performed (step S25: Yes), and the update information is stored in the key device 2 (step S26: Yes), the key device 2 transmits the update information to the electric lock control system 1. Even when the authentication process is successfully performed (step S25: Yes), if the update information is not stored in the key device 2 (step S26: No), the key device 2 does not transmit the update information to the electric lock control system 1.
- the lock-side controller 12 updates the control program of the lock-side controller 12 based on the update information received by the lock-side communication section 11 from the key device 2.
- the present embodiment enables the control program relating to the control of the electric lock 3 to be updated without using a dedicated maintenance device.
- the lock-side communication section 11 receives the update information of the control program in a state where the key device 2 is successfully authenticated by the authentication section 121. That is, the lock-side controller 12 updates the control program of the lock-side controller 12 only when the key device 2 is successfully authenticated by the authentication section 121.
- the present embodiment provides the advantage that the control program can be prevented from being illegally altered by an illegal apparatus without a new authentication means being prepared.
- a communication method is a communication method of a key device 2 including a first communication unit 221 and a second communication unit 222.
- the first communication unit 221 is configured to perform communication with an electric lock control system 1.
- the second communication unit 222 is configured to perform communication with a different system (a server 7) different from the electric lock control system 1.

- the acquisition step is a step of acquiring update information of a control program relating to control of an electric lock 3 serving as a control object of the electric lock control system 1 through the communication between the second communication unit 222 and the different system.
- the transmission step is a step of transmitting at least part of the update information of the control program, which is acquired to the electric lock control system 1 through the communication between the first communication unit 221 and the electric lock control system 1.
- a program according to one embodiment is a computer program including instructions which, when the program is executed by a computer system, cause the computer system to carry out the communication method.
- update of the control program may include addition of a function, for example, giving a remote control function to a key device 2 which does not have the remote control function.
- the lock-side controller 12 controls the electric lock 3 to lock or unlock the opening and closing member 5 and thereafter checks the presence or absence of update information, but the sequence of these processes may be reversed. That is, in FIG. 3 , the lock-side controller 12 may perform steps S14 and S15 before performing step S13.
- the lock-side communication section 11 receives the update information from the key device 2 when the key device 2 is successfully authenticated by the authentication section 121, but this should not be construed as limiting.
- the lock-side communication section 11 may receive the update information from the key device 2 regardless of whether or not the key device 2 is successfully authenticated by the authentication section 121.
- the lock-side controller 12 may update the control program of the lock-side controller 12 regardless of whether or not the key device 2 is successfully authenticated by the authentication section 121.
- the key device 2 acquires the update information of the control program in advance by, for example, updating a dedicated application, but this should not be construed as limiting.
- the electric lock control system 1 may acquire the update information of the control program from the server 7 by adopting the key device 2 as a relay. In this case, it is not necessary to cause the key device 2 to acquire the update information of the control program in advance.
