In this lock design, the lowest pin is the same length in each lock in the group, but the master wafer varies in length. In both cases, there is a gap at the shear line and the key is able to turn. The change key might raise the pins so that the shear line is just above the top of the master wafer, while the master key might raise the pins so the shear line is at the bottom of the master wafer. When three pins are combined in a shaft, there are two ways to position the pins so they open the lock. This third pin is called a master wafer or spacer.
In these locks, a few of the pin pairs are separated by a third pin. The change key will open only that specific lock, while the master key will open that lock and several others in a group. Some locks are designed to work with two different keys. The right combination of pins lines up perfectly with the notches in the key. The correct key will push each pin pair up just enough so that the point where the two pins come together lines up perfectly with the space where the cylinder and the housing come together - this point is called the shear line. The incorrect key will push the pins so that most of the top pins are still partly in the plug and partly in the housing.
