A master key system is designed to eliminate many keys being carried around and more than one being able to open a lock. The Master key would open all locks and an operating key would open only one lock. Therefore, two different cut keys would open the same lock. There are times when many different keys might open a certain lock such as a janitor or entry door. In this case there are many pins in the lock cylinder to allow the various keys to let the pins meet the shear line. The shear line is the area where the inner cylinder meets the outside shell or lock. When the pins are aligned at the shear line there is a gap and the cylinder can be turned. The more the pins in the cylinder, the more the keys can be used to open, to include those not part of a system. Some master keyed locks would be easier to be picked because of the large amount of possibilities to create a break at the shear line. A lock with many keys is a therefore more prone to a breach in security.
