What is considered strictly forbidden regarding key duplication?

Key duplication is a critical aspect of jail security, and certain practices surrounding it are strictly forbidden to ensure the safety and integrity of the facility. The process of duplicating keys without proper authorization poses a significant security risk. Maintaining a duplicate key at home can lead to unauthorized access should that key ever be lost or fall into the wrong hands.

By keeping a spare key outside of the secure environment of the facility, there is a potential for breaches that could compromise the safety of both staff and inmates. This practice undermines established protocols designed to maintain control and prevent unauthorized access to secured areas. The security of keys is paramount, and any practice that can lead to unwarranted access is strictly forbidden.

The other options, while related to key control and usage, do not address the same level of risk inherent in having unauthorized duplicates outside of the secure environment of the jail.
