Electronic locking devices, systems, and methods may require the utilization of an electronic key generated by an electronic key generation device. The electronic key may be generated using a data payload received from a server and/or an administrative device. The administrative device is enabled to remotely manage the locking device and locking system via, for example, a software application running on the administrative device and/or a website.

An electric lock includes a housing, a keypad module and a lock assembly. The keypad module is arranged on the housing. The keypad module includes a key panel, an electrode pad, a circuit board and a spacer. The key panel is marked with a plurality of key characters. The electrode pad is arranged on an inner side of the key panel, and the electrode pad has a plurality of key electrodes corresponding to the plurality of key characters respectively. The circuit board includes a plurality of key circuits. Each of the key circuits is configured to generate a key signal when contacting a corresponding key electrode. The spacer is configured to form a gap between each of the key circuits and the corresponding key electrode. The lock assembly is electrically connected to the keypad module for performing locking and unlocking operations according to the key signal.

The embodiments of the present disclosure disclose a method and system for controlling a device. The device control method includes: determining one or more sets, wherein the one or more sets include one or more preset rules each of which corresponds to a set of the one or more sets; including a first device into a first set of the one or more sets based on information of the first device; and controlling the first device in the first set to perform a corresponding operation according to a preset rule corresponding to the first set.

The administrative device is enabled to remotely manage the locking device and locking system via, for example, a software application running on the administrative device and/or a website.

According to various embodiments, an electronic device including a touch screen display may receive first information associated with a first electronic key of a first door lock, display a first graphic user interface (GUI) associated with the first electronic key to indicate an inactive status of the first electronic key on the display, receive first credential information associated with the first electronic key, and after receiving the first credential information, change the first GUI to indicate an active status of the first electronic key.

Rental property management technology, in which reservation data is accessed on a rental property management server, and a request from a mobile device for an upcoming reservation at a property is detected. In response to detecting the request, the rental property management server confirms the upcoming reservation based on the accessed reservation data. In response to confirming the upcoming reservation, the reservation management server generates a unique access code. The rental property management server transmits the unique access code to the mobile device and to a monitoring system on the property. The rental property management server also transmits data to the monitoring system indicating that the unique access code grants access to the property.

Present disclosure relates a secure electronic lock system. Secure electronic lock system includes many secure electronic locks connected through a communication network to a secure electronic lock system server. Each secure electronic lock includes a passive electronic lock, an active electronic key and a passive electronic key. Active electronic key includes electrical power source providing electrical power supply to active electronic key, passive electronic lock and passive electronic key. When both active and passive electronic keys are inserted into respective electronic keyholes of passive electronic lock, both active and passive digital keys are transmitted to passive electronic lock, passive electronic lock can be locked and unlocked only when both active and passive digital keys received match prestored active and passive digital keys respectively. Active and passive digital keys are updated and an access event is transmitted to secure electronic lock system server every time each secure electronic lock is accessed.

A watercraft rental system is used to rent an owner's watercraft to a user. The watercraft rental system includes a computer and a user terminal. The computer communicates with the watercraft and records rental condition information of the watercraft. The user terminal provides borrowing request information to the computer. The borrowing request information corresponds to a response to the rental condition information. The computer executes a rental process of the watercraft based on the borrowing request information.

A center, configured to communicate with an OTA master configured to control software updating of an electronic control unit via a first network, includes a processor. The electronic control unit is installed in a vehicle. The processor is configured to store vehicle management information including key information used for authenticating the vehicle, receive an authentication signal from the vehicle via the first network. The authentication signal is signed using a unique key imparted to predetermined equipment installed in the vehicle. The processor is configured to perform authentication of the vehicle based on the vehicle management information and the authentication signal, and when the processor receives the key information from the vehicle, rewrites the vehicle management information stored by the processor based on the key information.
