North Carolina Locksmith Practice Exam

What is defined as one or more cut(s) in a key that are constant across all levels?

1. Row Master Key

2. Single Key Section

3. Rotating Constant

4. Sub-Master Key

The correct answer is: Rotating Constant

The term that refers to one or more cuts in a key that are constant across all levels is the concept of a "Rotating Constant." This means that no matter which level of the locking mechanism is engaged, specific cuts on the key remain unchanged, providing a consistent fit that can open multiple locks within that system. This is particularly important in master key systems where various keys can access different locks, but certain cuts allow for broader access across multiple levels of the system. In contrast, terms like "Row Master Key," "Single Key Section," and "Sub-Master Key" have different implications in the context of key design and functionality. For instance, a Row Master Key typically refers to a master key configuration that may access a specific row of locks, while a Single Key Section relates to a key that serves only one specific part of a master key system. The Sub-Master Key provides access to a subset of locks under a more comprehensive master key system. However, these are not defined by the constant nature of specific cuts across all key levels, which is why "Rotating Constant" is the most fitting term for the question.
