摘要

A lock system is disclosed. The lock system includes a lock and one or more keys. The lock includes a plurality of tumblers configured for interaction with associated key features. A tumbler includes at least two sections and defines at least two contact points. One contact point is configured to interact with a feature included on either of an operator key or a master key, while the other contact point is configured to interact with a feature included on a separate key. A key according to the present disclosure includes features configured to interact with a contact point on each tumbler, such as with only one of the two contact points. One of the keys may include channels defined on surfaces thereof. Such channels accommodate the set of contact points that the features of such key are not interacting with, allowing access to and interaction with the appropriate set of contact points.
