The term that describes a key provided by the lock manufacturer is “original.” An original key is crafted specifically for a lock by the manufacturer, ensuring that it perfectly fits the mechanism of that lock. This key includes design features and specifications that are unique to that particular lock model, allowing for optimal function and security.

In contrast, duplicate keys are replicas made from an original key, typically created by a locksmith or key-cutting service. Master keys are designed to open multiple locks, offering broader access than a single lock's original key. Skeleton keys are simplified versions of keys often used historically to open a variety of locks, but they do not represent the specific key provided by a lock manufacturer.
