Locks are the most acceptable and widely used security devices for protecting facilities, materials and property. All containers, rooms, and facilities must be locked when not in actual use. Regardless of their quality or cost, locks are considered delay devices only. Some locks require time and expert manipulation to open, but all locks can be defeated by force and with the proper tools. Locks must never be considered as a stand-alone method of security.
The systematic control of locks and keys is one of the most important components of any security program. Without proper key control, locks provide little deterrence to illegal or unauthorized entry into a facility.
The National Park Service recommends the fewer the keys there are, the better:
- Keys multiply over time, particularly at the master and grand master levels. Unchecked, this quickly compromises the access control program.
- Good key control requires ongoing maintenance and cooperation by all staff.
- Lost or stolen keys increase the risk of loss.
- Lack of accountability invites unauthorized possession and duplication of keys.
