EVVA 3KSplus

3KSplus is a reversible key system which is characterised by a unique functional principle. In contrast to classic locking systems, the blocking elements in the 3KSplus cylinder are moved without springs and are not pressed against a spring force. This means maximum security and wear resistance.

Thanks to the immense variation possibilities, complex locking systems can be calculated.

The organisational, legal and highest technical key protection guarantees top duplicate key security. The patented curve guide ensures even greater security and easier key insertion.

This system is available for reorders only.

For new systems, we recommend the successor series EVVA 4KS.

Technical characteristics:

modular design (SYMO)
springless technology
12 springless, massive locking pins are brought into a specific position via positive control of the six key curves and scanned by 2 control bars
blocking bar in the core controls the additional coding of the key
carbide drilling protection in core and body
picking and scanning protection (has several locking pins and it is not possible to tell which locking pin is effective in each individual case, free movement of the locking elements in the core makes scanning almost impossible)
impact key protection
pulling and tear-off protection by carbide metal side control bar and the modular design (SYMO)
certified according to DIN EN 1303:2008
patent protection until 2025

Options / Special equipment:

different cylinder finishes (burnished, brass polished)
increased drilling protection
emergency and danger function
freewheel
weather protection
modular design

Explanations on the optional extras:

Cylinder finishes:

standard finish: nickel (shiny)
optional: brass (front polished), brown (patinated)
for individual design requirements
if desired, homogeneous appearance of door cylinder and fitting
optional staining cannot be combined with: seawater resistance, dust and weather protection

Please note:
If a different finish, different from the standard finish, is ordered, extended production times may occur.

BSZ - double cylinder lockable on both sides, danger function:

This function enables the locking cylinder to be blocked even if a key with blocking authorisation is inserted on the opposite side.

This option is only possible from a cylinder length of 31/36 mm.

SEW - Seawater resistance:

for cylinders that are exposed to strong environmental influences
cylinder parts susceptible to corrosion are delivered with a special surface finish
Please note:
When ordering this option the delivery time will be extended.

SSW - protection mechanism against dust and weather influences:

Spring-loaded locking plates integrated in the locking cylinder, which open and close automatically when the key is inserted or removed. This design is one-sided on the outside.
The cylinder is extended by 3,3 mm.

Please note:
When ordering this option, the delivery time is extended.

Freewheel function 360° (on request):

single freewheel only for double cylinder and half cylinder
the coupling is driven via the tip of the key
from cylinder length: 31/36 mm possible
restrictions possible in combination with other optional equipment
Freewheel function (FZG): freewheel with forced decoupling / forced controlled decoupling of the locking nose, the clutch is driven by the tip of the key, suitable for gear anti-panic multipoint locks (Only if mandatory by the lock manufacturer.)

Key with design cap:

colours: black, blue and red, yellow, green and white
material thickness Design cap: 7,2 mm
plastic caps for special design requirements for the keys
ergonomic design and high quality for better haptics
easy optical differentiation
simple management of locking systems through colour assignment
consecutive numbering of the key (key with the same locking authorisation receives a consecutive number)
use exclusively for EVVA keys
factory assembly, subsequent opening and retrofitting is not possible
