Key bitting is typically organized in three columns to facilitate a systematic approach to key cutting and duplication. This organizational method allows locksmiths to arrange the depth of cuts on a key according to a standard format. Each column represents a specific position on the key, with each position being assigned a depth that corresponds to the pin heights in a lock.

This columnar arrangement makes it easier for locksmiths to read key cuts and to ensure that they match the specifications required for a particular lock. By utilizing three columns, it also aids in efficiently managing key codes, thereby enhancing the accuracy of key duplication and the overall security process. The three-column method is widely accepted in the industry, ensuring consistency when creating keys for different types of locks.

The other options reflect less standardized or systematic approaches. Organizing bitting into four distinct groups would complicate key duplication rather than simplify it. Position differences might be relevant in specific contexts but do not provide the clarity and order needed for practical locksmithing tasks. Random assignment would undermine the entire purpose of having a systematic method, leading to potential issues with compatibility and security in locking mechanisms.
