2–4 A2 System Service Manual
DEFINING A MASTERKEY SYSTEM
Definition of a
masterkey
system
A masterkey system is often misunderstood because it is not a tangible
product and can have many variations. A BEST Masterkey system can be
customized to meet any particular customer needs.
Masterkeying is a mathematical process that shows the number of
different combinations available within a given plan and allows all cores
to be combinated into your system. It also assists the user in controlling
the doors that people can access in the given facility.
Several security levels of keys are usually able to operate a single lock in
a masterkey system. This feature offers flexibility as well as control to
your system. Careful planning and consultation with your BEST
Representative can help you maximize the benefits and avoid common
pitfalls of a masterkey system. In most systems, 7-pin cores are used
because they permit more combinations and allow greater flexibility for
future expansion.
General design
guidelines
BEST Representatives use the following guidelines when designing a
customized masterkey system for the customer:
■Design the keying system around the function of the building and
not the actual organization, if possible.
■Develop a simple design.
■Try to predict where, when, and how people move throughout the
building.
■Plan for any future expansion that may be needed.
■Recognize the families of keys that are established, because they can
restrict the flexibility of the system.
Moreover, once a system is established, it is not necessary to use all of
your codes at one time. Codes may be set up as needed. Then, if growth
occurs, BEST refers to its own secure files for the remaining available
combinations. This activity is conducted as directed by the customer. It
is the customer’s responsibility to keep track of which core markings
have been used in a given series.

Interchangeable
core
The standard figure-8 core that is interchangeable throughout the entire
product line is a major feature of BEST. This interchangeability permits
BEST locks of any type, size, or style to be masterkeyed into one system.
Therefore your system can easily expand to include new facilities. Also,
no BEST core needs alterations to fit any other BEST lock. You simply
remove the core with the control key and insert a new core that
operates by different keys. This unique feature lets you perform a re-
lock in seconds. See page 5–9.
Keys It is important to understand several key terms to more fully
comprehend the concepts of masterkeying. See Figure 2.2.
Control key
The control key installs and removes the interchangeable core in your
BEST system. The control key has the same security level as a
grandmaster and must receive the same level of protection.
Grandmaster key
The grandmaster key operates all locks in a masterkey system (unless
locks are specifically excluded from the grandmaster for security or
safety reasons such as cash boxes, drug cabinets, hazardous waste areas,
and so forth).
Master key
The master key operates a large group of locks. For example, one
master key can have access to an entire building, floor, or department.
Submaster key
The submaster key operates a smaller group of locks that are part of a
master group.
Operating key
The individual key is also known as the operating key and is the lowest
level key. This key operates only one lock or keyed-alike group of locks.
(This type of key is also called “change key” in the locksmith industry.)
It is important to note that keying is not limited to just the organization
of the keys listed above. More levels in the hierarchy may be created if
needed. For example, a sub-submaster key level may be added.
Overview of a Masterkey System
A2 System Service Manual 2–7
Keyways The keyway of a core is a specific design or shape of the key blade and
is manufactured into the core plug. This specific design keeps keys of
other keyways from working in a dissimilar core. The keyway shapes
can be grouped into the following categories:
■Standard keyways
■Restricted keyways
■Patented keyways.

Codes One of the most significant elements of a masterkey system is the codes
on which the entire system is based. Codes are the number sequences
that directly relate to key cuts and indirectly relate to the pin segments
or combinations within the interchangeable core. Codes originate at the
corporate headquarters and are used by BEST offices to establish
systems around the world. All codes remain proprietary property of
BEST.
Codes are only supplied to the customer when BEST authorized service
equipment has been ordered and received. Once generated, the codes
arrive in the form of a code sheet or bitting list. This sheet then
becomes a printed record of your keying system. It contains
information about your system that is highly confidential. See page 5–8
for an example of a code sheet.
SYSTEM ORGANIZATION AND SIZE
The size of your system is determined by the following factors:
■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 estimate
your future core needs by doubling the number of locks determined by
the site survey. Then you will have codes available when you need to re-
key one or several locks due to lost or stolen keys. Planning for extra
codes will also let you add an additional building or wing under the
same system.
The pin size of cores refers to the number of barrels in each core. BEST
uses 7-pin cores as a standard in order to provide greater flexibility in
the number of combinations that can be generated. However, if your
existing system uses 5-pin or 6-pin cores, BEST offers these pin sizes as
well. Using 5-pin or 6-pin, though, will decrease the number of total
combinations that are available to you.
Manufacturing tolerances, as designed, are a vital factor in consistent
key control. For each specific system, keys and core segments must be
designed to mate exactly as coded. BEST holds a very close tolerance
throughout its product lines.
Your BEST Representative can help you determine which options not
only meet your facility’s current needs, but also provide maximum
flexibility and efficiency as your system evolves.

A2 System Service Manual 2–9
SYSTEM SECURITY
To increase the level of security within your system, you need to
protect sensitive security products or information. These may include:
■Code sheets
■Service equipment
■Authorized security personnel contacts
■Key/core inventory.
BEST will help you with these procedures by maintaining code records
at local BEST offices. In addition, authorized security contacts are kept
on file. These contacts are people who are responsible for receiving all
products and information. Security policies and procedures such as
these help assure the integrity of your keying system.
Overview of a Masterkey System
2–10 A2 System Service Manual
KEY AND CORE CONTROL
A good mechanical locking system involves more than hardware. A key
and core control system is a recording and filing plan that provides
complete information on keying, doors, locks, and personnel. The
system should include formal policies and procedures to regulate the
distribution and control of key, core and code issuance. The following
five elements must be controlled in all lock and key systems in order to
maintain security:
■Keys
■Cores
■Forms
■Doors
■People.
Common
control
problems
Based on a survey conducted by BEST, security system users revealed
the following problems with managing and administering the locking
system:
■Loss of keys—either lost or stolen
■Not retrieving keys from employees that have been replaced or have
retired
■Management indifference to security problems
■Theft—internal and external
■Too many keys issued
■Poor management of records resulting in keys being misplaced or
stolen by employees within the facility
■Code expansion without BEST involvement
■Too many people involved with the system.
G-Series forms Keeping accurate and up-to-date records is essential for the overall
management of a BEST system. It is important to use adequate forms, in
detail, to account for all keys/cores in your facility. The BEST G-Series
form system provides color coding, cross-referencing, and space for
continuous relocks and key changes. Contact your BEST Representative
to obtain these forms.
Keystone 600
Software
For larger systems (systems with 100 or more users), the Keystone 600
Software is the recommended means of maintaining the A2 System.
BEST’s Keystone 600 key and core control software is a valuable tool for
managing records. This user-friendly, Windows-based system allows for
expedited entry of data and the generation of multiple standard reports.
This program records, cross-references, and accesses all key and core
information. Modeled after the proven G-Series form system,
Keystone 600 helps you to efficiently make the transition from a manual
system to a computer.

system and need more flexibility.
Description
Standard keyway BEST offers standard keyways for general use by customers
that are compatible with existing systems and provide a cost
effective means for system expansion.
Restricted keyway BEST offers non-patented keyways, which BEST restricts by
volume and proximity usage for limited distribution.
Patented keyway BEST offers patented keyways that cannot legally be
duplicated by other manufacturers.
Options and Applications
A2 System Service Manual 4–3
SPECIAL OPTIONS AND APPLICATIONS
The following table describes special core options that BEST offers for
the A2 System and gives examples for when they are used.
Option Description Application
Key trap core When the key is inserted into the core and is
turned, the key is trapped in the core. The key
cannot be returned vertically nor withdrawn
from the core. The core and trapped key must
be drilled out of the lock.
This special core is modified at the factory to
match the key that you want to trap.
Eliminates a key from the system
by trapping it in the core. This
option is useful if a key has been
lost, or if someone has a key and
will not return it.
Keyway blockout blade†This blade prevents any and all keys from being
inserted in a core. A special extractor key must
be used in order to remove the blockout blade
from the keyway.
Prevents keys from having access
to a given entrance. This option is
useful to have in case of a natural
disaster or a specified job action
such as a strike or lockout.
Wear resistant core Hardened stainless steel segments are used as
the bottom segments in each barrel of the core.
Provides longer life for cores in
high traffic areas such as entry
doors or other frequently used
doors.
Pick resistant core Spooled segments are used as the top and
bottom segments in each barrel of the core.
Provides enhanced resistance to
picking the core. This option is
useful for high security areas such
as narcotics rooms, special
equipment rooms, or cash offices.
Drill resistant core Hardened ball bearings are used in the throw
pin holes and hardened stainless steel segments
are used at the top and bottom segments in the
first two barrels of the core.
Provides enhanced resistance to
drilling the core. This option
provides an added measure of
security for areas listed above.
Pick and drill resistant core Hardened ball bearings are used in the throw
pin holes and hardened stainless steel segments
are used as the top and bottom segments in the
first two barrels of the core. Spooled segments
are used as the top and bottom segments in
each remaining barrel of the core.
Provides enhanced resistance to
picking and drilling of the core.
This option provides an added
measure of security for areas listed
above.
Core dust cover Stainless steel spring-loaded dust cover is
installed over the keyway.
Prevents the keyway from
accumulating dust and dirt. This
option is useful for cores exposed
to the elements such as doors in
high humidity climates, selected
doors in chemical plants, or for
low use exterior doors.
Note: If the core is housed in a
cylinder, use the cylinder dust
cover instead of the core dust
cover for maximum protection.
† See page 3–4 for illustrations of the keyway blockout blade and extractor key.

5 CHANGES TO THE A2 SYSTEM
This chapter contains guidelines for determining
your A2 System needs, guidelines for working with
BEST when making changes to the A2 System, and
also includes possible re-lock options.
Changes to the A2 System
5–2 A2 System Service Manual
DETERMINING YOUR NEEDS
Questions to
consider
There are several questions that customers should consider when
assessing what changes need to be made to the A2 System including the
following:
■How many keys did I originally plan for?
■How many new locks do I need now and approximately how many
will I need in the future?
■How many codes do I have left for my system?
■How many master keys do I want (see page 2–8)?
■Are there any special options or adaptations that I want
(see page 4–3)?
■Do I have specific security needs or concerns about
re-locks (see page 5–9)?
The way that your system was originally customized may affect how
you go about making changes or expanding the system. For instance, if
you did not originally plan to add on to your facility, then there may not
be enough codes saved to do so. It is necessary to contact your BEST
Representative to help you determine how to resolve any issues that
may arise.
WORKING WITH BEST
Surveying the
facility
After the initial assessment of the system has been made, a physical site
survey is conducted for new areas of the facility. Your BEST
Representative will inspect and assess all of the requirements associated
with securing your facility. The goal of a site survey is to systematically
gather information that allows a thorough analysis of each access point.
This analysis helps identify all necessary hardware requirements. It also
organizes valuable information about the feasibility of integrating
additional buildings, wings, and so forth into a system. The survey can
then be used with the system schematic to determine how each lock is
to be keyed/programmed. For an example of a site survey, see
Figure 5.1.
Changes to the A2 System
A2 System Service Manual 5–3
Figure 5.1 Sample site survey
Changes to the A2 System
5–4 A2 System Service Manual
Designing the
schematic
The keying schematic is a plan or blueprint that illustrates the various
levels of security you need for the BEST system. These levels are defined
and designated into specific groups. The schematic design is similar to
an organizational chart, as shown in Figure 5.2 and Figure 5.3.
General guidelines
When designing a masterkey system schematic, BEST Representatives
follow these guidelines:
■Initially structure a control and grandmaster level.
■Determine how the facility is to be grouped as far as buildings,
locations, wings, floors, departments, and so forth. The first
grouping or level usually determines the master level of keys.
■Develop a second level of control within a building, floor, or
wherever necessary by creating a submaster group. Additional levels
or groups can be created if needed.
■Determine codes for masters, submasters, and any additional
groupings.
■Design special levels of access or restriction for additional system
flexibility.

RE-LOCK OPTIONS
The process of adapting existing locks to meet new needs is referred to
as a “re-lock.” Re-locks within your facility can vary from a simple one-
core re-lock to complex total re-locks. Some of the variations in
masterkeying which may apply to established BEST systems are listed
below.
Guidelines for performing re-locks
When performing any re-lock procedure, be sure to follow these
guidelines to ensure the security of the system:
■Use only authorized system codes from BEST.
■Use the code sheet to determine which barrels need to be
combinated.
■Recombinate only the barrels necessary for the new combination.
■Always record which combinations have been used to avoid any
duplications.
Option Description
Core change replace all cores with newly combinated cores on an
emergency (immediate) or periodic (pre-planned) basis
Recombinate total core recombinate every barrel in an existing core
Partial recombination recombinate some barrels in an existing core
Departmental re-lock replace all cores in a department with newly
combinated cores on a periodic basis
Rotation of cores preplanned from one floor or department to another

A2 SYSTEM BASIC PROCEDURES OVERVIEW
Combinating
cores
Overview of using a code sheet
When you need to combinate new cores, you should get code sheets
from your BEST Representative. For an illustrated example of a code
sheet, see page 5–8.
For detailed instructions with illustrations on combinating cores, see
the Core and Key Service Manual (T35527) or contact your BEST
Representative.
General guidelines for combinating cores
■Use only authorized system codes from BEST.
■Begin combinating from the rear of the core and work your way to
the face of the core.
■Always complete the pin loading process for each individual barrel
before proceeding to the next barrel.
■Never split pin segments. For example, do not use two number 2 pin
segments in place of a number 4.
Basic steps for combinating cores
1. Make sure that the core plug turns freely before you begin
combinating.
2. Align the barrels to receive segments.
3. Load the segments into the core.
4. Load one spring per barrel.
5. Place one cap onto each barrel.
6. Check the core for proper operation by inserting a key in the core.
If you can insert, turn, and remove the key easily, then the core and
key are working properly.
7. Check the control key for proper installation by inserting the
control key into the core and turning it. If you can turn the key
15° clockwise and the core can be removed, then the core and
control key are working properly.
Service and Maintenance
A2 System Service Manual 6–3
Cutting keys Keys may be cut to any combination up to seven digits long using your
BEST key combinator. If your organization needs a key combinator,
contact your BEST Representative.
For detailed instructions with illustrations on cutting keys, see the Key
Combinator Service Manual (T35532) or contact your BEST
Representative.
Caution
Always keep fingers and hands out of the way of moving parts. Be
especially careful of the pinch point between the base and operating
handle.
Basic steps for cutting keys
Use BEST original key blanks to ensure consistent results. With the
machine bolted down or free standing you can start cutting keys.
1. Load a key into the key combinator.
2. Cut the key.
3. Unload the key from the key combinator.
4. Test the key for proper measurements.
Stamping cores
and keys
For detailed instructions on stamping cores and keys, contact your BEST
Representative.
General guidelines for stamping cores and keys
To avoid causing any damage when stamping cores, follow these
guidelines:
■Do not use a metal-headed hammer on cores and keys.
■Do not use excessive force to stamp core markings on the side of
cores. Excessive force may cause the barrel opening to deform.
■Do not stamp the core on the bottom lobe. Stamp only the top lobe.
Basic steps for stamping cores and keys
1. Be sure that you have selected the appropriate die and that it is
facing the correct direction.
2. Place the core/key into the selected holder to hold it in place.
3. Stamp the core/key with a ball-peen hammer.
4. Continue this process until the desired marking is complete.

6–4 A2 System Service Manual
Installing cores For more detailed instructions on how to properly install cores into
locks, see the Core and Key Service Manual (T35527) or contact your
BEST Representative.
Installing new cores
After you have combinated new cores, you may choose to install them
into the locks on your own. It is important to install cores in an
undetectable pattern to ensure that your system is protected. It may be
possible for someone to figure out the pattern if the cores are installed
in the order in which they were combinated.
Checking cores for proper installation
Once your cores have been installed in an undetectable order, be sure
to check that they have been properly installed. Insert the operating
key in the core. If you can insert the operating key, turn, and remove
the key easily, the core and key are working properly installed.
Periodically test all of your keys, including the control, grandmaster,
and operating keys in the core to make sure that the core is operating
properly.

A2 System Service Manual 6–5
DEVELOPING A KEY CONTROL SYSTEM
Key control is one of the most important aspects of any security
program. Without proper key control, unauthorized entry into your
facility is possible. It is essential that each operating facility implement
an adequate key control program.
Purpose of a key
control system
Experience has shown that keys are often handled carelessly. They are
loaned, duplicated, exposed to theft, abused, and lost. Often there are
no up-to-date records tracking keys that have been distributed, keys that
have been lost, keys that are still in the custody of employees no longer
employed at the facility, and spare keys that have not been officially
issued. At some locations, spare keys to important exterior doors are
displayed in the open, sometimes even hanging on a nail inside the door
that the key unlocks. To adequately protect company assets, you must
eliminate such practices and implement formal, positive key controls.
The guidelines below serve as the minimum standards of key control for
all of your facilities.
A good key control system effectively manages any size network of
locks by pinpointing the responsibility of each individual and by
providing quick access to information on all locks, keys, and personnel.
It also stores additional keys, lock parts, and service equipment. The
system shows who has keys to which locks, and when each key has
been issued or returned.
Objectives of a key
control system
Develop a key control system with the following objectives in mind:
■Limit the number of keys distributed to individuals.
■Maintain a record of the location of every lock that is used in the
facility, with the number of the BEST core assigned to the lock.
■Maintain a record of the location of all lock numbers and BEST cores.
■Maintain a record of all keys that have been issued, showing the
number of the key and the name of the holder, as well as a record of
keys not issued.
■Maintain a record of all keys held by each individual, with signatures
for each key held.
■Securely store all key records, spare codes, spare keys, and key
equipment.
Updating key and
core records
It is important to update your key and core records when making
changes to the masterkey system. When records are not properly
updated, it becomes too difficult to maintain your high level of security.
Unless information has been properly recorded, there can be no way to
trace a key back to the proper holder.
Service and Maintenance
6–6 A2 System Service Manual
General guidelines for recordkeeping
Accurate records allow management to track facts quickly and hold
each employee accountable. The following tips will help you maintain
your records:
■Keep key records on updated forms, not code sheets.
■Record every key issue and return immediately.
■Record every core placement and change immediately.
BEST recommends using the Keystone 600 software program when
your system exceeds more than 150 individuals. Otherwise, BEST offers
the G-Series paper forms to ensure effective key control.
G-Series cards
and equipment
The following cards and equipment are essential to implement a key
control program if you do not have the Keystone 600 software
program. Contact your local BEST Representative to obtain the G-Series
cards and equipment. Refer to the table below and the figures that
follow for descriptions of the listed G-Series products.

Tips for managing your cores
■Destroy all worn cores but do not throw them in the trash.
■Do not leave any barrels empty when loading the core.
■Do not keep a file of your pin segment order for combinating cores.
Planning for
emergencies
Setting aside extra codes
It is important to have extra codes set aside in the event that you need
to change several or all of the locks in a particular area of your facility.
For instance, if an employee’s master key is lost or stolen, then the
cores for the locks that the key has access to need to be recombinated
or replaced.
Having precombinated cores available
In the event of an emergency where you need to replace a core, you
may want to have precombinated cores at your disposal for a quick and
efficient changeover. You may need to replace only one particular core,
but it is possible that you will need to replace several cores at once
(page 5–9).
Emergency blockout blade
If no other measures can be taken, you can insert a keyway blockout
blade into a core to prevent unauthorized entry (page 4–3). The
blockout blade requires a special tool to remove it from the core.
Contact your BEST Representative to order blockout blades and the
removal tool.
