The classic system with
robust technology:
mechanical locking systems
Future-proof solutions,
perfect in quality
IKON – The locking systems specialist since 1926

»»Ò³
Since inventing and patenting the profile cylinder over
eighty years ago, IKON locking cylinders have been set-
ting standards in many countries throughout the world.
When the patent was granted, it gave rise to the age of the
so-called security cylinder. This is a legacy which we are
committed to and which we are proud of.
The profile locking cylinder is almost always used wherever
doors are locked and need to be secured against unauthor-
ised entry. Today, this cylinder represents the key compo-
nent in lock and door security systems. We are still supply-
ing keys and lock cylinders today for locking systems which
were installed as far back as eighty years ago.
Our invention and expertise -
IKON is the original and the
company has shaped developments
in lock and security technology for
over eighty years

+CLIQ is a mechatronic
locking system for
upgrading existing
IKON mechanical
locking systems.
An IKON mechanical locking system:
a worthwhile investment in your safety and security
IKON mechanical locking systems have been
proving their worth for decades in countless
buildings - on company premises, in institu-
tions or in residential buildings. Almost no other
manufacturer in Germany has more locking
systems on the market or is able install larger
and more complex systems than IKON. IKON
mechanical locking systems impress due to their
reliable technology, perfect precision, optimum
quality and proven long life cycle. No specific
expertise is required to manage a mechanical
locking system, so building operators can do it
themselves or ask an IKON specialist dealer to
do it on their behalf. Each IKON locking system
is supplied with a locking plan, security card and
its own security number. Replacement keys and
new locking cylinders can only be ordered from
the factory through an IKON specialist dealer
and if a security card is shown. IKON locking
cylinders offer optimum protection against
common break-in techniques. They meet the
requirements of various DIN classes and are
optionally supplied with VdS certification.
No matter how large or complex your locking
system becomes, our service is there to assist
you for a lifetime. IKON mechanical locking
systems are thus future-proof solutions and
undeniably a worthwhile investment.
An option for a later stage:
an upgrade to +CLIQ will meet increased requirements
Situations may arise where your mechanical locking system requires
support from mechatronic components. Such situations could include a
higher security level being required for sensitive areas in your building or
the need for greater flexibility for access authorisations. The solution
lies in IKON +CLIQ technology.This system integrates chip technology
into mechanical locking cylinders and their corresponding keys. Access or locking is thus
controlled on two levels: through mechanical locking and through electronic identity.
A locking system’s
structure exclusively
depends on individual
requirements.
An IKON-brand locking system
is always tailor-made –
planned by professionals and
customised to your needs
A locking system is always a unique affair. No
locking system is ever the same as any other. A
multitude of different factors already play a role
at the needs analysis and planning stage. Such
factors include precise requirements and size as
well as the structure and use of the building or
system. For instance, a so-called central locking
system is preferable in a residential complex
while a hierarchical locking system is more suit-
able for industrial premises or an administration
building. Cost issues also play a decisive role. Last
but not least, the locking system must be open
and flexible with regard to accommodating any
future requirements.
Regardless of individual requirement profiles,
one thing is certain: you will always make the
right choice with an IKON locking system.
Questions you need to answer before the planning stage:
How is your building used?
What is your organisational structure like?
How strict are your security requirements?
What other requirements need to be satisfied? – For instance, with regards to insurance.
Locking system planning step by step:
Individual needs analysis
Design of macrostructure
Drafting of an organisational chart
System checked and accepted by users, client, architects and planners
Decision on system type, system and profile

The world of locking clylinders:
systems, profiles, types
If you talk about systems in a locking cylinder,
you are first referring to the number of pin
tumblers and other security codings. A system’s
profile is featured on the key’s long side and runs
parallel to the key’s spine. It varies according to
its security category and whether it is a vector
profile, multi-profile or locking wave profile.
A cylinder type refers to its exterior structural
shape. It is selected in accordance with type of
use and can accommodate different systems and
their respective profiles.
Locking system organisational structures:
hierarchic or central
Different access rules apply in companies and
administration buildings to those in residential
buildings. This is why we differentiate between
hierarchic systems and central locking systems.
In hierarchic locking systems (GM, M), access
authorisations are regulated in accordance with
clear structures. This enables each employee
to have a key to their office while managers
have keys to their departments and executive
managers hold the general master key for all
doors. In the case of central locking systems
(C, CM) in residential buildings, the key opens
one of the smallest units – for instance, an
apartment – as well as access to the apartment,
associated units such as mail boxes and base-
ments as well as superordinate doors such as
the main entrance. There is no access to other
units, such as other apartments and mail boxes.
In order to satisfy all conceivable requirements,
different hierarchical system and central lock-
ing system functions can also be combined in a
single system (ComMC).
The security card
A security identity card is supplied with every
IKON locking system. This security identity
card is used for verification purposes when
re-ordering keys and locking cylinders from
the manufacturer or requesting locking system
data and locking plans. It must be shown to the
specialist dealer when re-ordering components
from the factory.

Little engineering marvels:
IKON mechanical locking cylinder systems
No matter how many locking cylinders ones are
finally included in the plan for your new locking
system, mechanical locking cylinder systems
will always form a secure basis for the system.
IKON mechanical locking cylinder systems are
available in four different versions and security
categories: as System SK6 with vector profiles
in security class 1 and 2, with multi-profiles and
with a locking wave profile, which also features
a so-called undercut. These locking cylinder
systems are described on this page and the fol-
lowing two pages.
System SK6
Vector profile
in security class 1 and 2
The key profile in security class 1 features
a very special layout which hinders manual
unauthorised entry techniques considerably.
Compared with standard key profiles, the vector
profile in security class 1 also stands out due
to its optimum protection against lock pick-
ing, decoding and copying. The vector profile
in security class 2 features an additional coding
on the key, which is read by additional blocking
elements in the locking cylinder. This type of
control on the side of the key profile ensures
there are more options regarding combining
and organising systems and also provides even
greater protection against lock picking and key
copying.
If a key with missing or incorrect coding is used,
the locking action will be blocked.

System SK6:
Locking wave profile with undercut
System SK6:
Multi-profile
The multi-profile ensures even greater protec-
tion than the vector profile. This profile features
additional crescent-shaped notches along one
or both sides of the key length. This coding is
read by special springless locking slider com-
ponents in the locking cylinder. If a key with
missing notches is used, the locking action will
be blocked. Using a multi-profile in a locking
system ensures there are more options regarding
combining and organising systems while provid-
ing even greater protection against lock picking
and key copying.

System SK6, which features a locking wave
profile with undercut, represents the highest
security category in IKON mechanical locking
cylinders. Acting as an extra coding feature, the
so-called locking wave is cut into the sides of the
key length and is read by special spring-mounted
tumblers in the locking cylinder. As in the other
systems, if a key with missing or incorrect coding
is used, the locking action will be blocked. An
undercut is also milled into the key profile. This
increases protection against lock picking, break-
ins and copying.

An aid to better understanding:
our brief glossary on
locking cylinders
Decoding protection
Decoding protection refers to the degree of difficulty in
ascertaining the tumbler locking codes in a locking cylin-
der surreptitiously, using suitable tools but without using
undue force, in order to cut a duplicate key in accordance
with the dimensions which have been revealed.
Drilling protection
IKON profile cylinders are fitted with
drilling protection as standard. The
hard metal pins used in the cylin-
der core and housing, for instance,
prevent the locking cylinder from
being drilled open. Increased drilling protection in security
category 1 and 2 can be supplied to meet special locking
system security requirements.
Lock picking protection
Lock picking protection refers to the degree of difficulty
in unlocking the locking components in a locking cylinder
with suitable tools without using the original key and
without using undue force. IKON locking cylinders feature
a whole range of precautionary measures to prevent at-
tempted break-ins with picking tools: paracentric key pro-
files, blocking rails, blocking pins, finger pins and locking
wave mechanisms. IKON locking cylinders offer optimum
protection against lock picking.
Installation lengths
The basic length of a double profile cylinder is generally 61
mm (L = 30/30). Besides standard lengths, which can be
extended in 5 mm increments up to a total length of 140
mm, special lengths are also available in 10 mm incre-
ments up to a total length of 240 mm.
DIN class
German Institute for Standardization
(DIN) security classification. All
VERSO CLIQ locking cylinders featured
in this brochure comply with DIN EN 1303/ DIN 18252.
These standards, which define the requirements for
high-grade locking cylinders, cover measures such as key
control as well as protection against lock picking,
decoding, key copying, drilling and core extraction.
Emergency mechanism
Each authorised emergen-
cy key within an IKON lock-
ing system can open or lock
double profile cylinders
fitted with an emergency mechanism, even when there is
another key inserted in a lock position on the other side.
Core extraction protection and locking cylinder
extraction protection
Core extraction protection and lock-
ing cylinder extraction protection
with integrated drilling protect (VdS
approved) are available for IKON
profile cylinders to prevent the core
or locking cylinder from being pulled
out of the lock.
Key copying protection
The large number of possible locking configurations and
low manufacturing tolerances ensure the risk of an IKON
locking cylinder being unlocked with a different key is kept
to an absolute minimum.
Surface finishes
IKON locking systems can be perfectly matched to the
particular style of your doors. Besides the standard nickel-
plated matt finish, other surface finishes are available
for profile cylinders, furniture cylinders and outdoor
cylinders.
Nickel-plated matt
Brush-finished matt
Polished brass
Chrome-plated matt
Browned
VdS class
Certification mark issued by VdS-Schaden-
verhutung, the German insurance industry’s
certification centre. All IKON locking cylinders
described here can be optionally supplied with
VdS certification.
Much more than a locking system:
integrated security technology
for the whole building
Whether for companies, institutions, govern-
ment agencies, industrial premises or adminis-
tration buildings, you can always completely
rely on IKON security technology. When install-
ing a new locking system, it’s exactly the right
moment to consider security equipment which
offers more than just access control. Important
documents can be securely stored secured
behind a solid furniture lock, for instance. A
series of mini-safes are available for embed-
ding in walls or in floor. Such safes can also be
optimally integrated into locking systems with
corresponding lock cylinders. As far as security
for windows is concerned, there are also lockable
window handles which are ready made to hold
profile half cylinders. If you also wish to provide
fire safety and emergency evacuation systems,
escape route technology from IKON’s sister
brand effeff is ideal. Your new locking system is
thus given a few extra dimensions and will bring
comprehensive added benefits, which will prove
to be a worthwhile investment, not only in the
event of a break-in.
Escape route technol-
ogy for emergencies:
The effeff Escape Door
Terminal 1385 can be
seamlessly integrated
into switch ranges by
well-known electrical
installation and intel-
ligent building control
system manufacturers.
