Keycards

The Key Cards are used to open a secret door in the Treehouse of Secret Agent Clank. There are three key cards: blue, red and yellow.

The location of the key cards.

Blue

 * At the second "minecart" in the Gadgebot level in Fort Sprocket, Go backwards instead of forward.

Red

 * The key card is in the second Clank level under and left of the 2nd set of police cars.

Yellow

 * The key card is in the Saint Qwark level where you will have to free the Space Nuns.

The last Space Nun you get to (the one you use the cannon on) don't use it yet! Turn around. Face the eyeball and jump of the Gray platform where the cannon is. You will be blasted forward to the key card.
