[0025] 1, the locking / unlocking system 10 includes a second locking / unlocking device 14. The second locking / unlocking device 14 is a device that locks and unlocks a passenger side door 24 of a vehicle 20 through the use of a mechanical key. The passenger side door 24 opens and closes an entrance on the side where a passenger seat 25 is located in a passenger compartment 22 of the vehicle 20. The passenger side door 24 is an example of a second opening / closing body.

[0026] According to the configuration of this embodiment, even if close-proximity wireless communication or short-range wireless communication cannot be performed due to over-discharge of the battery of the vehicle 20 or insufficient charge of the mobile device 50, the user 40 can unlock the passenger door 24 using the mechanical key and enter the vehicle compartment 22. The second locking / unlocking device 14 using the mechanical key is arranged in a door different from the driver's door 21, so that it is possible to provide an alternative locking / unlocking method in the event that wireless communication becomes impossible while easing the constraints on the arrangement of the communication device 12 for locking / unlocking based on wireless communication in the driver's door 21. Therefore, it is possible to improve the convenience of the vehicle 20 in which the opening / closing body is locked and unlocked using close-proximity wireless communication or short-range wireless communication.

[0027] In particular, since the second locking / unlocking device 14 using a mechanical key is arranged on the passenger side door 24, which faces in a different direction from the driver's side door 21, the freedom of the exterior design of the vehicle 20 on the side where the driver's side door 21, which is most frequently seen by the user 40, is located is increased, which contributes to improving the exterior design of the vehicle 20.

[0028] The above-described embodiment is merely an example for facilitating understanding of the present invention. The configurations according to the above-described embodiment may be appropriately modified or improved without departing from the spirit and scope of the present invention.

[0029] The opening / closing body in which the second locking / unlocking device 14 is disposed is not limited to the passenger door 24. As illustrated in Fig. 1, the second locking / unlocking device 14 may be configured to lock and unlock a rear door 27 or a back door 28. The rear door 27 opens and closes an entrance on the side of the rear seat 26 in the passenger compartment 22. The back door 28 opens and closes an entrance behind the rear seat 26 in the passenger compartment 22. The rear door 27 and the back door 28 are examples of the second opening / closing body.

[0030] According to this configuration, even if it becomes impossible to lock or unlock the driver's side door 21 based on wireless communication, the mechanical key can be used to unlock the rear door 27 or the back door 28, allowing immediate entry into the vehicle compartment 22. In particular, when the second locking / unlocking device 14 is disposed in the back door 28 facing in a different direction from the driver's side door 21, the degree of freedom in the exterior design of the vehicle 20 on the side where the driver's side door 21, which is most frequently seen by the user 40, is located can be increased.

[0031] Alternatively, the second locking / unlocking device 14 may be configured to lock and unlock the bonnet 29. The bonnet 29 opens and closes the engine room or the luggage compartment. The bonnet 29 is an example of a second opening / closing body. The bonnet 29 faces a different direction from the driver's door 21, so that the degree of freedom of the exterior design of the vehicle 20 on the side where the driver's door 21, which is most frequently seen by the user 40, is located, can be increased. However, since the space opened and closed by the bonnet 29 is independent of the passenger compartment 22, a mechanism for forcibly unlocking the door needs to be provided in the space. The same applies to the back door that opens and closes the trunk. [Explanation of symbols]
