In locksmithing, which of the following refers specifically to the visual representation of key bittings?

1. Key Bitting Array

2. Key Profile Schedule

3. Lock Identification Chart

4. Bitting Summary

The correct answer is: Key Bitting Array

Key bitting refers to the specific cuts or notches on a key that correspond to the internal mechanisms of a lock. A key bitting array is a visual representation that illustrates the precise depths and patterns of these cuts across multiple keys in a system. This array is essential for locksmiths during the key duplication process or when designing a new key for a particular lock. By representing the key bittings visually, the key bitting array enables locksmiths to understand the layout of cuts that is required for a key to function within its designated lock. This tool helps ensure accuracy in cutting new keys and is crucial in maintaining security and functionality in locking systems. The other options, while related to locksmithing, do not specifically capture the concept of visual representation of key bittings as effectively as the key bitting array does. For instance, a key profile schedule generally catalogs the different key profiles used in a system without directly illustrating the bitting. Similarly, a lock identification chart focuses more on identifying locks and their features rather than detailing the cuts on keys. A bitting summary might provide a written list or overview of bittings but lacks the visual component pivotal for locksmithing tasks.
