A network lock system and a method for operating the network lock system. The network lock system includes: a battery controller for turning on a microcontroller using power in a battery, in response to a determination by the battery controller that there is enough power in the battery to turn on the microcontroller; the microcontroller after being turned on, for receiving a wireless signal and in response, for generating a lock signal to activate a device adapter; the device adapter for applying a power signal to a lock mechanism, in response to the device adapter having been activated by the lock signal; and the lock mechanism for locking a first lock part to a second lock part together, and for releasing the first lock part locked to the second lock part in response to the lock mechanism having received the power signal from the device adapter.
