Wikipedia definition
4. Key (lock)A key is an instrument that is used to operate a lock. A typical key consists of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. The blade is usually intended to operate one specific lock or a small number of locks that are keyed alike.
