What's a SKELETON KEY?
Does it look like a Skeleton to you? A SKELETON KEY is basically a master key, one that has been modified or created to grant its possessor passage to all the rooms in a dwelling. The reason why it is called a "SKELETON" KEY is due to its shape that somewhat resembles that of a skeleton. Well, at least it resembled a skeleton to those who used those keys. In Spanish there is not an equivalent to SKELETON KEY, or Passkey as it is also called. But a Master Key is called LLAVE MAESTRA.
