Locked Minds + ONLINE VIDEO

LOCKED MINDS is a unique prediction lock routine that seems impossible, but is so easy!
And this effect comes with a precision-made push button lock!

There are many ways to present this effect- but here is the one Peter uses:
First, let the customer hold the lock, and confirm that it is indeed locked closed.
Take the lock back, punch in the correct 4-number combination and show the spectator that the lock now opens.
Then close the lock again, and you are ready to start the effect.
Explain that you are going to "lock minds" with your spectator.
You are going to mentally project the four-digit combination to him!
To make the process faster, you are going to use ten cards, each with a digit printed on it.
You place the cards in two piles, and let the spectator eliminate one of the two piles.
That leaves five numbers in the selected pile.
The spectator is now handling the pile of cards.
To make it more random, have him do a one-off shuffle (one card is put from the top to the bottom, the next card is laid on the table, etc.) until four cards are on the table, and one is still in the spectator's hand.
That final card is eliminated to the side.
The four cards that are on the table are now laid face up, revealing the four digits.
Let the spectator push the four digits on the lock.
The lock does not open.
Now, "lock minds" with your spectator.
With both of you concentrating, let your spectator rearrange the order of the digits.
This time, when the spectator punches the numbers on the lock, the lock opens!
