The term that refers to the one-pin master key for all combinations listed on the same line is known as a Row Master Key. In the context of locksmithing and key systems, a Row Master Key is specifically designed to work with a series of locks that share a similar configuration or layout, meaning that all the locks listed on the same line of a master key system diagram can be operated by this single key.

This design is particularly useful for applications where multiple locks need to be accessed by authorized personnel using a simplified key management strategy. By allowing one key to operate multiple locks in a row, it helps in maintaining ease of access while still providing some level of security.

In contrast, the other terms represent different concepts in key management. A Standard Master Key is typically used to operate a specific set of locks but is not limited to a single line of key combinations. A Change Master Key usually permits access to locks that require a different functioning level beyond just the row configuration, and a Single Key Section refers to a unique key used for individual locks without a master key function. Understanding these distinctions is essential for effective locksmithing and key management practices.
