The control module outputs a wakeup signal upon receipt of an input signal. The transmission module is to be awaken to an awaken state from a sleep state upon receipt of the wakeup signal, and outputs a confirm signal based on the input signal. The server unit receives a remote signal containing an unlock condition associated with the confirm signal, and outputs an unlock signal to the control module to cause the electronic lock device to operate in an unlock state upon receipt of the unlock signal when the unlock condition is satisfied. ## Claims ### Claim 1 An electronic lock system comprising: an electronic lock device that includes an input module configured to output an input signal in response to a user input;
