Are there key-operated built-in locks approved for storing classified information?

• A. Yes.
• B. No.
• C. Only certain models.
• D. It depends on security policy.

Answer: (B)

Key access alone doesn’t provide enough control for storing classified information. A key-operated built-in lock creates a single point of control: anyone with the key can open it, keys can be lost or copied, and there’s usually no reliable way to verify who accessed the contents or when. For classified material, policies require stronger access control, often with dual- or multilateral authorization and an auditable record of access, along with locks that meet approved standards. Because of these needs, key-operated built-in locks are not considered approved for storing classified information.
