One of the greatest threats to key control within your facility is the unauthorized duplication of keys; one simple solution is the use of a patent-protected keying system. Yet the selection of the right patented keying system can be anything but simple. Many variables come into making a sound decision.
• How do I control interior security?
• Should perimeter security receive greater attention?
• Will I be able to quickly and easily service the system?
• Can I set up a sound masterkey system?
• Will I be able to meet budgetary constraints?
Very seldom can a single product meet all of your exact needs, and often your level of convenience must be sacrificed to fit the capabilities of the product.
With the new MX8 Patented Keying System by Stanley-Best Access Systems, you don't need to compromise. The MX8 Patented Keying System provides you, the end user, with an significant amount of flexibility, enabling you to customize a solution that fits your unique balance between security and convenience.
VERSATILE APPLICATION
The MX8 Patented Keying System is available in two series of
keyways, the M Series and the X Series. Each series offers a different
blend of features to help you maximize convenience while optimizing
your security.

M Series Keyway Features
- Patented keys operate both MX8 and Standard BEST cores (backward compatibility) with certain existing BEST keyways (for example the JKLM keyways). Standard keys do not operate MX8 cores.
- Available in large bow, long blade, and long nose key blanks to work with special applications.
- Available in core designs for use in special application locks, such as high security mortise, hotel cylinders, and glass display-case locks.
- Utilizes the same combinating kits and key cutting equipment as the Standard BEST keyways. M Series keys operate MX8 cores and Standard (non-patented) BEST cores. Standard key blanks do not operate MX8 cores.
X Series Keyway Features
- Distinctive key design includes thicker key blanks with larger bow for added strength and easier handling.
- Keyways are unique to MX8 Patented Keying System offering even higher key duplication protection.
- Requires only minor modifications to key cutting equipment to accommodate new keyways. X Series keyways utilize the standard combinating kit, minimizing the expense of system changeover.
- X Series keys only operate MX8 cores.
HOW IT ALL WORKS
MX8 keys and cores are available exclusively through Stanley-BEST
sales offices. To help assure that key blanks do not end up in the
possession of unauthorized personnel, Stanley will only sell key blanks
to individuals designated by the CUSTOMER, and only after validating
the individual is an authorized purchaser.
MX8 cores are compatible with all existing BEST figure 8 core lock housings, eliminating the need for new or modified locks.
Long term utility patent guarantees extended life of keying system.
