This lets the person with the master key access any lock in the group, while someone with a change key can open only his or her own lock. 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. Two or more locks which can be operated by a single key (. Some locks are designed to work with two different keys. MASTER KEYING -A master keyed lock can be operated by two or more keys which are NOT cut the same. The right combination of pins lines up perfectly with the notches in the key.

For example, an apartment building owner can unlock all doors and locks however the tenant can only unlock one door. The levels of keying and complexity required within the master key heirarchy. The size of the system needed and the number of pin chambers in the cylinders. D Repeat until all cuts have a corresponding numberfrom bow to the tip of key. C Write down number and proceed to the next cut. B Slide key left until it stops on a number. Move key to first cut, or notch, from the key bow. Most master key systems work in a hierarchical way, providing various levels of access and control for a secure site. First lets consider the basics of masterkeying: Your system design will be impacted by the following factors: The type of lock and bitting system in use.
