According to TCJS 259.154, keys and locks for detention doors shall be ________.

The correct answer is based on the requirements set forth by the Texas Commission on Jail Standards (TCJS), which stipulates that keys and locks used for detention doors must be of a specific type to ensure security and safety within the facility. Mogul and paracentric locks are designed with features that provide a higher level of security compared to standard locks, making them more suitable for correctional environments. These locks are often resistant to manipulation and forced entry, thereby enhancing the overall safety of the jail and its inhabitants.

Using mogul and paracentric locks aligns with best practices in jail management, where the security of both staff and inmates is a top priority. Other types of locks—while they may be effective in different contexts—do not meet the specific criteria established for detention facilities as specified in TCJS. Therefore, the requirement for mogul and paracentric locks reflects the need for enhanced security measures in a correctional setting.
