What document should be kept to identify keys for each lock and their current location and custody?

• A. Key and lock register
• B. Inventory log
• C. Access authorization list
• D. Incident report

Answer: (A)

Maintaining physical security requires clear accountability for every key. The document that records which key goes with which lock, where that key is currently located, and who is entrusted with it is the key and lock register. By keeping this register, you have an auditable, up-to-date trail of custody that helps prevent loss, supports rapid responses in emergencies, and simplifies audits and inspections. The other documents have different purposes: an inventory log tracks items and quantities, an access authorization list shows who is allowed to enter areas, and an incident report logs security events. None of those provide the ongoing key custody tracking that a key and lock register does.
