A padlock and 6 keys are shown. With the help of a spectator it is confirmed that only one key opens the lock. A large denomination bill is then placed inside a plexi-glass case and locked with the padlock. The keys are mixed up in a paper bag and 5 spectators are each asked to select a key. They are told they get to keep the bill if their key opens the lock. They can switch keys as often as they like but no matter their keys will not work. Only the key left for the performer will open the lock! No Forcing of any kind.
