Overview of a masterkey system
A failure in either of these areas will jeopardize the integrity of your
system. To ensure that your system is not corrupted, BEST masterkey
experts are responsible for creating all codes.
System
organization
and size
The size of your system is simply the total number of codes you have
available to use at your facility. You need to consider the following
factors to help you make this determination:
■
■
■
the number of individual locks you need
the pin size of your cores
the code system you need
The number of actual locks you require is taken from the information
you received from the site survey. A general rule-of-thumb is to take this
total and double that number. This will allow you to have codes
available when you need to rekey a lock because someone lost their
key. It will also let you expand your system if you add an additional
building or wing that needs to be on the same system. Of course, this is
merely a general rule and may vary according to your needs.
The pin size refers to the number of barrels in a core. BEST uses sevenpin
cores as a standard in order to provide greater flexibility in the
number of combinations generated. However, you may have an existing
system that uses five or six pin cores to which you are trying to adapt.
BEST does offer these other pin sizes, but with each decrease in the
number of barrels in the core, the less total combinations you have
available.
The code system refers to one of three systems used to establish your
facility’s codes. The three systems are:
■
■
■
A2 system
A3 system
A4 system
Although each system offers a different total number of available codes,
that is not the only criteria to apply in selecting the system you need.
Each system has benefits and limitations which need to be considered
before the selection is made.
Your BEST staff can help you determine which options are not only
right for your facility, but also those that will give maximum life and
efficiency to your system.
