What is not a responsibility of the Key Custodian?

• A. Maintain an up-to-date key inventory
• B. Change or rotate locks quarterly
• C. Grant access to authorized personnel
• D. Track key issuance and returns

Answer: (B)

Changing or rotating locks quarterly isn’t a responsibility of the Key Custodian. The key custodian’s role centers on controlling the keys themselves: keeping an up-to-date inventory so you know what keys exist, granting access only to authorized personnel, and tracking who has issued keys and when they’re returned. Rotating or changing locks is a physical security task involving hardware and potentially rekeying, which typically falls to facilities management or a professional locksmith rather than the key control process. It’s a security action that operates outside the day-to-day key-management duties, which is why it’s the option that doesn’t fit.
