How often are keys and padlocks inventoried by serial number?

• A. At Least Once Every 6 Months
• B. Every Month
• C. Annually
• D. Every 2 Years

Answer: (A)

Regular serial-number inventory of keys and padlocks is a security control that keeps ownership and access under tight oversight. These items are high-risk; if a key is lost or a padlock becomes unassigned, unauthorized access becomes possible. Checking them at least every six months provides timely detection of discrepancies without creating an overwhelming administrative burden. Daily or monthly checks would add unnecessary work for something that doesn’t change as rapidly, while annual or biannual checks leave longer windows for misplacements to go unnoticed. The process is straightforward: compare each item’s serial number to the asset records, confirm its location and custodian, and update records or reissue keys as needed. This cadence helps ensure only current holders retain access and that all keys and padlocks remain accounted for.
