A high-security key is characterized by its protection through patents, which prevent unauthorized duplication. This means that not just anyone can make a copy of a high-security key; specific permissions are required, ensuring that only authorized individuals or locksmiths have the ability to duplicate the key.

The design and mechanics of high-security keys often include additional security features, such as unique cuts or specific materials that enhance their resistance to unauthorized access. This makes them ideal for environments requiring stringent security measures, such as government buildings, commercial properties, and safes. The patent protection not only limits duplication but often indicates a higher level of manufacturing quality and security technology compared to standard keys.

In contrast, other options either describe keys with lower security standards or do not emphasize the critical feature of legal restrictions on duplication that defines high-security keys.
