A progressive key notching system that includes a plurality of key notches positioned along at least one surface, such as, for example, a top surface, of a key blade. Each of the plurality of key notches includes a central axis. The central axes of at least one pair of adjacent key notches are separated by a distance that is different than a distance separating another, adjacent pair of key notches. Further, when the key blade is operably positioned within a key slot, at least one of the central axes may be offset from a chamber central axis of an adjacent retention pin chamber. Moreover, one or more of the chamber central axes may be aligned with a portion of a trailing surface and/or leading surface of an adjacent key notch. |
