Kontrol Key Brass
A large two inch brass padlock is gimmicked in a most ingenious manner. Several keys are not gimmicked..Any of these keys can be controlled by the performer to open or not open the lock.
It does not matter whether the performer
or a spectator tries to open
the lock, it will open or not controled by the magician.
This is a close-up mehanical version of Theo Anneman's Seven Keys to Baldplate. Complete with several ideas for presentation.
