The Access 3™Advantage
The Access 3 Key System
The patented Access 3 system from
Corbin Russwin provides the right level
of security for each opening in your
facility. Three levels of ANSI/BHMA Grade
1 protection, from patented keyway to
UL437 certified, secures every opening.
A common key for all three levels of
security enhances key control and
simplifies administrative procedures. Key
blanks are controlled through authorized
distribution and geographical protection
is available. Available for mortise,
rim, component and Large Format
Interchangeable Core (LFIC) cylinders,
Corbin Russwin offers the right Access 3
level of protection for every door in your
facility.
Benefits
• Patent protection from unauthorized
key duplication through 2027
• New keyway family protects system
integrity from legacy systems
• Keys are significantly stronger than
competitive systems
• User-friendly design with minimal
components provides easy field
service
• Availability in all existing Corbin
Russwin cylinder types provides cost-
effective upgrade for Corbin Russwin
facilities
• Bump resistance standard for all AP,
AS and AHS cylinders.
Access 3 (AP) features a utility patented
keyway. These cylinders easily retrofit into
existing hardware and are appropriate for
most applications. The keys for AP can
only open AP cylinders. AP cylinders are
protected against bumping.
Access 3 (AS) builds on the utility
patented keyway of AP and adds
patented side bar locking with unique
angled bottom pins that provide end
users with geographical exclusivity.
Cylinders provide protection against
bumping and picking. Because of
its superior key control and patent
protection until 2027, AS products are
recommended for use in conjunction
with AHS for new installations or when
retrofitting systems, including large
format interchangeable core systems.
Access 3 (AHS) combines the utility
patented keyway and side bar locking
with unique angled bottom pins that
provide end users with geographical
exclusivity, and adds certification to
UL437. They are classified as high security
because of their superior resistance to
physical attack and protection against
unauthorized key duplication. Because of
its superior key control, patent protection
until 2027, and physical strength, we
recommend AHS products for new high-
security installations or when retrofitting
systems, including large format
interchangeable core systems. Corbin
Russwin also offers anti-vandal and
high security locksets that complement
AHS cylinders for those openings most
vulnerable to attach.
IMPORTANT: Corbin Russwin AP key
systems are available with 7 depths of
cut while AS and AHS are only available
with 6 depths of cut. AP systems can
utilize all 7 depths in system design as
a way of increasing overall key system
size only if not integrated with AS and/
or AHS systems. If AP patent protection
is the only requirement in the key system
and there is no expectation of combining
with AS or AHS levels of security, then all
7 depths are available for use. If AP is to
be combined with AS and/or AHS only 6
depths of cut are available.
