Dead Lock by Michael Murray - a high-precision psychological weapon that makes the impossible feel real! 

The premise is as clean as it gets: You hand a genuine solid lock to a participant. Without you saying a word or touching the device, they are guided by their own intuition to input the one specific four-digit combination that clicks it open. Whether you are revealing a secret PIN or a participant’s exact date of birth, the moment the lock springs open in their hands, you are guaranteed a great reaction.

Why Dead Lock is a Must-Have:

• The magic happens in their hands, not yours. 
• This is a custom-manufactured lock designed specifically for the rigorous demands of professional performers.
• If birthdates are used, it can easily be calibrated for US MM/DD format, ensuring your performance feels natural regardless of where you are in the world.
• Your purchase grants you access to an exclusive Facebook community and online video packed with advanced routines and handlings.
