Abstract

A set of locks can be unlocked by a key for each lock and a super-key can unlock the whole set of locks. Like the common lock, a key can unlock one instead of those of the set of locks by driving its core in rotation. However, the super-key can unlock all the locks of the set of locks. A rotation stopper can be driven to two positions to unlock, one position is by a key and another is by the super-key.
