context_page_description: A key is an object used to open and close locks. Many things have locks, for example, doors. Keys are also used to turn on cars, machines and other things.
  A key is used by placing the key into the slot of the thing you want to unlock.
  A key that can open more than one lock is called a master key or skeleton key.
