The Swiss Army Mult-Key

Key chains are great, they hold all of your keys and  jingle nice melodies.  But they can get over-sized, unorganized and too bulky.  This idea for an improved key chain is inspired by Swiss Army Knives.  Instead of blades and tools flipping out from various locations keys would flip out.

The only negatives are trying to pick out the correct key (maybe color code the keys) and I have always thought it is hard to pry out the particular tool needed on Swiss Army Knives so I assume it may be difficult to pry out your keys.   We can think of ideas to improve those things.
