1. B - Utility patents protect against the unauthorized manufacture (and duplication) of keys.

2. D - Utility patents are in force for 20 years from the date of application, providing for protection against unauthorized manufacture of your keys.

3. False - A sequential serial number on a restricted key provides a simple system to maintain knowledge and control of all keys issued.

4. False - A lost key is worth much more than the actual cost of the key. The potential cost is, at a minimum, the cost to rekey all the doors that it operates, and potentially all of the valuables that are behind those doors.

5. True - The easiest way to gain entry to a locked door is with the use of an unauthorized key.

6. False - A policy and procedure to collect keys from employees as they leave helps to maintain the security and investment in a good security system.

7. True - By having a written key control policy, outside vendors (such as cleaning people) or others with keys are aware of the protections included in the system, as well as their liability in maintaining security.

8. True - But what really improves the security of the system is insuring that keys cannot be copied, along with a deposit requirement, so that students/employees must notify you if keys are lost.

9. False - Only a utility patent that is defended by the manufacturer provides real assurance that your system is secure. Stamping keys "Do Not Duplicate" provides "feel good security"...not real security.
