Abstract
A key or key blank includes a key blade having a first edge, a second edge, and first and second opposed sides. The first edge has one or more edge bittings to elevate and/or rotate one or more tumbler pins of a lock with a vertically-oriented keyway, and one of the opposed sides has one or more side bittings to elevate and/or rotate one or more tumbler pins of a lock with a horizontally-oriented keyway. Side warding surfaces on the key blank are shaped and positioned to minimize the interference of peaks between the skewed bitting cuts on the key. A lock has a keyway configured for the key having edge bittings to elevate and/or rotate one or more tumbler pins of a vertical lock and side bittings to elevate and/or rotate one or more tumbler pins of a horizontal lock.
