What does a Block Master key manage in a keying system?

1. Only one lock

2. A specific group of locks

3. All combinations listed as a block

4. Pins of different lengths

The correct answer is: All combinations listed as a block

A Block Master key is designed to provide access to multiple lock combinations within a specific grouping, often associated with a master key system. It manages all combinations that are categorized under that block, allowing for one key to operate an entire set of locks which may be configured with those specific combinations. This system is particularly useful in environments where certain users need access to a number of locks without the need for multiple individual keys, thus enhancing convenience and security management. The ability of a Block Master key to operate all locks within its defined group is essential for effective administrative control in facilities like apartment complexes, office buildings, or educational institutions, allowing designated personnel controlled access while maintaining security. In terms of the other options, managing just one lock or a specific group of locks doesn’t fully capture the broader capacity of a Block Master key, which is focused on accessing all combinations within its designated block. While pin lengths are an essential aspect of how locks are configured, they don’t directly relate to what a Block Master key manages in terms of operational capability.
