If there are 5 pins and either an 'on' or an 'off' for each, then there are only so many combinations possible. There WILL be repeats, and a lot of them. Same is true for old-style car keys. Your keys will open about 1 in 25 of every similar car (GM, Ford, etc,) in the mall's parking lot. The situation is better now that the mfgs put computer chips on the keys, too.
