A lock includes a housing and a key-operated lock core mounted on the housing. The key-operated lock core has a spindle with a keyhole defined therein. The spindle is movable between an original position where the spindle is allowed to be rotated with respect to the housing to put the lock in a locked or unlocked state, and an indicative position where the spindle is also allowed to be rotated to put the lock in the locked or unlocked state.
