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 details
- 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
Execution
- reversible key system

- weather protection
- seawater version
- freewheel (on request)
Description of the additional options
Cylinder finishes
- standard finish: nickel
- optional: brass (front polished), brown patinated, black patinated
- optional finishes cannot be combined with: seawater resistance, dust and weather protection
- for individual design requirements
- if desired, homogeneous appearance of door cylinder and fitting
- 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 lock cylinder to be locked even if a key with locking 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 lock 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).
