Manual, key-operated locks are the most common type of security device used to control access through doors. While many companies have installed sophisticated electronic access control systems, the manual lock is still used on most doors. In addition, many doors that are controlled by an electronic access control system still have a manual lock on them that allows override using a key.
Most manual locks that are in use today are using technology that was developed more than eighty years ago. While this technology has proven reliable, standard manual locks have many weaknesses.
Some of these weaknesses include:
To solve many of the weaknesses of standard locks, "high-security" locks have been developed. There are many different brands and styles of high-security locks, but most offer the following benefits:
Silva Consultants strongly recommends the use of high-security locks, particularly on the exterior doors of your facility. High-security locks are also a good choice for use on doors that lead into areas that contain sensitive information or high-value assets.
Here are a few manufacturers of high-security locks:
ASSA Lock, Inc.
ASSA is extremely popular in Europe and other parts of the world. ASSA is starting to become a widely-used brand of high-security lock in the USA.
This venerable old-time lock manufacturer makes a high-security clock cylinder called the Pyramid.
Schlage Locks is a well-known manufacturer of residential and commercial lock hardware. Schlage's high-security lock is called the "Primus". The Primus system works primarily with locks manufactured by Schlage. Versions of the Primus key can operate both the Primus lock and Schlage's standard locks, making them ideal for use at facilities that already have a Schlage lock system in place.
Arguably the most popular brand of high-security lock used in the USA. Largest selection of high-security locks, lock cylinders, cam locks, and padlocks. Medeco lock cylinders can be installed in most existing locksets without requiring replacement of the lock itself.
Interesting product, relatively new in the United States. Now a division of Assa-Abloy.
