Bitting refers to the specific pattern of cuts made on a key that correspond to the pins inside a lock. These cuts are crucial because they deepen or raise the profile of the key to precisely match the heights of the pins in the lock cylinder. When the key is inserted into the lock, the bitting aligns the pins at the correct heights, allowing the lock to turn and operate smoothly. The accuracy of the bitting is essential for the lock's security and functionality, as even slight misalignments can prevent the lock from opening.

Understanding bitting is vital for locksmiths when cutting or duplicating keys since the exact configuration must replicate the original key to ensure proper locking mechanism engagement. This insight into the key's design helps locksmiths maintain the integrity and security of the locking systems they work with.
