The anciant Egyptians were the first to come up with a complicated security device. This was the pin tumbler lock.

We use the same security principle today on millions of applications. The most commonly used lock today is the pin tumbler lock. A series of pins that are divided at certain points must be raised to these dividing points in relationship to the seperation between the cylinder wall and the shell of the lock by a key cut for that particlar series of pin divisions. Thus the cylinder can be turned, and the mechanism or lock is unlocked.
