Which lock is appropriate for a storage closet when you want to deter entry but not require high security?

• A. A built-in lock
• B. A high-security padlock
• C. A digital keypad lock
• D. A magnetic lock

Answer: (A)

A simple, integrated mechanism that is built into the door or cabinet provides the right balance for a storage closet: it deters casual entry without adding the complexity or cost of high-security systems. A built-in lock is easy to install, reliable, and sufficient to discourage unwanted access while remaining inexpensive and low-maintenance. In contrast, a high-security padlock is more protection than needed for a closet, a digital keypad lock introduces electronics and code management, and a magnetic lock depends on power and access control infrastructure, which isn’t necessary for this scenario.
