Abstract
A host system and a method for unlocking an electronic lock are provided. The host system includes a chassis, an electronic lock and a system circuit board. The chassis has a side door. The electronic lock is arranged on the side door for locking the side door on the chassis. The system circuit board is configured in the chassis, coupled to the electronic lock, and the system board has a plurality of universal serial bus ports. When the system board is not activated and a trigger voltage is received, the system circuit board detects an input sequence in which the USB ports are being inserted, and when the input sequence is equal to a predetermined sequence, the system circuit board outputs an unlock signal to the electronic lock so as to unlock the electronic lock device.
