Which type of key is specified for detention use?

• A. Ward
• B. Paracentric
• C. Pin tumbler
• D. Tubular

Answer: (B)

Detention-use security relies on locks that resist unauthorized manipulation, often by using restricted or unusual keyways. A paracentric keyway is offset or irregular, with wards positioned in a way that complicates insertion of tools and makes generic picks or non-authorized keys less effective. This design helps ensure that only specially cut, authorized keys can operate the lock, which is crucial in confinement facilities where access control is critical. In contrast, other types like warded locks are easier to bypass with simple tools, and standard pin tumbler or tubular keyways don’t offer the same level of restricted access.
