What does the term "Bitting" refer to in locksmithing?

1. The designation of a key combination for future reference

2. The number(s) that represent the dimensions of the key

3. The shape of the key cut

4. The process of duplicating a key

The correct answer is: The number(s) that represent the dimensions of the key

The term "Bitting" in locksmithing specifically refers to the number(s) that represent the dimensions of the key. This includes the depth and spacing of the cuts on the key that correspond to the pins inside the lock. It is crucial in determining how the key will interact with the lock mechanism. The bitting essentially controls how the lock will respond when the key is inserted, allowing for proper engagement or disengagement of the locking mechanism. Having precise measurements for the bitting is essential for ensuring that a key will function correctly with a specific lock, as any alterations can prevent the key from turning smoothly or engaging the pins inside the lock. This concept directly ties into the manufacturing and duplication of keys, as understanding the bitting layout is a critical step in creating a key that works effectively with a particular lock model. In contrast, the designation of a key combination pertains to referencing a specific key pattern; the shape of the key cut relates more to its visual profile; and the process of duplicating a key involves creating a new key based on an existing one, rather than precisely defining the key's bitting.
