Abstract
One embodiment of the present invention provides a lock-and-key system for an electrical power plant. The system includes a plurality of locks and a smart key. A respective lock is installed with a standardized lock core, and the lock is associated with a lock identifier (ID). The smart key includes a key head that matches the standardized lock core; a lock-ID detector configured to detect the lock ID; a rotation stopper which, when enabled, is configured to prevent rotation of the key head while the key head is inserted into the standardized lock core; and a control module configured to disable the rotation stopper based on the detected lock ID, thereby facilitating the smart key to unlock the lock by rotating the key head.
