Question: 1 / 435

What is the significance of the number of columns in the key bitting array?

It determines the strength of the key

It influences the complexity of the combination

The number of columns in the key bitting array is significant because it influences the complexity of the combination. Each column represents a specific cut depth on the key, and having multiple columns allows for a wider range of possible key combinations. This increased complexity enhances the security of the lock system, as it minimizes the likelihood of unauthorized access due to guessing or trial-and-error methods. A greater number of columns typically means that there are more potential combinations of cuts, making it more difficult for intruders to create a duplicate key or gain entry without the original key.

While other factors may contribute to the overall security and production costs of a key, the primary role of the columns in the bitting array is to create a more intricate and varied set of possible keys that can match the lock's internal mechanism.
