Keyed-up first saw the light of day in 2005.
A card is signed and placed back into the pack. You say that there is a secret..a key to being able to find cards face-down exact...the cards are spread and and shown to see one card that has a picture of a key on the back of one card...its is shown to be the signed selection. Then as an after thought you visually cause the picture to become a REAL key and is taken off the card!
I would open up with this routine in my rest. sets all the time..and it never failed to get gasps!
