A borrowed ring is locked on a 4 digit combination brass lock, the dials are mixed by the magician and the spectator can hold on to the lock while the dials are mixed and spectator can test a few times that the lock cannot be opened. Spectator thought of a 4 digit number and put the numbers on the lock by herself. This proves to be the secret code that opens the lock! Spectator retrieves her ring from the lock in the end.

Important points:

• Work is pure mechanical, nothing will break, no skill needed, and it is built to last.
• Nothing is added or taken away- except maybe your spectator’s breath!
• No electronics parts, no remote control
• No magnets, no PK rings
• No threads, no wires
• No buttons, no switches
• No gravity switch, no directional limit
• No timers
• Lock can be in spectator’s hand from the beginning to end of performance
• Reset in 2 seconds and right under the nose of the spectators
• It seems impossible! But there is no force of any 4-digit pre-set numbers! – You truly don’t know what 4 digit number will be chosen – the selection of the 4 digits is as fair as it gets.
• Remember this: Spectators set the chosen numbers on the lock. They open it themselves!
