Abstract
This invention relates to a lock, which includes a housing and an indicative lock core. The indicative lock core is operable by a key to move to an indicative position and be stuck in the indicative position. The indicative lock core can move back to its original position only through a restore mechanism. When the key-operated lock core is in the indicative position, the key-operated lock core is partly situated outside the housing and is easily noticed.
