The primary purpose of sectionals in pin tumbler locks is to facilitate a system where multiple locks can be keyed alike while still utilizing distinct change keys. This allows for greater flexibility in managing access across several locks. For instance, in scenarios where different areas or rooms require different access levels, sectional designs permit the creation of keys that operate specific locks without compromising security across the entire system.

Each sectional component can be designed to match a specific set of pins, offering unique combinations that keep the overall system secure. Therefore, while one master key can open several locks, each lock can also have its individual key for additional security measures. This design efficiency enables locksmiths to meet client needs more effectively by ensuring control over which keys operate which locks, thus enhancing the usability of the locksmith’s products.
