3KS, 3KSplus locking system

3KSplus (3 Curve System plus) works with a unique and patented system that requires no springs. Unlike conventional locking systems, in the 3KSplus cylinder the locking elements move along the curves on the key and are not pushed against a spring force.
During the locking action, the 3KS key is scanned a total of 4 times – this is three times more than with other systems. The springless locking pin function guarantees utmost wear resistance and protection against picking. This technology means that there are reams of variations for cylinder master key systems.

3KSplus Key
3KSplus keys are designed as reversible keys. A smooth insertion of the key into the cylinder is made possible thanks to the two rounded key tips. They also guarantee the best possible key copying protection.

The system has three different safeguards that protect against keys being copied or tampered with:

• Organisational protection
  Keys are only made for authorised individuals with the necessary proof of legitimacy (e.g. security card).
• Legal protection
  The commercial manufacturing of keys only takes place at EVVA and at EVVA-authorised manufacturers. Furthermore, EVVA protects against the unauthorised manufacturing of 3KSplus keys by means of patented features on the key.
• The best possible technical protection
  Keys have technical features that require specialised machines and expert specialist knowledge for their manufacture.
   

3KSplus Integration
Mechanical locking systems are the foundation of organisational building security. A combination of electronically controlled security technology creates all-encompassing security solutions.

Integration through electronic identification technologies
3KSplus keys can be designed as Combi Keys that carry identification technology (e.g. Mifare, Legic, iButton etc.). This transforms the mechanical key into an electronic ID.

Motorised cylinder
Motorised cylinders can be integrated into a 3KSplus master key system. These cylinders can be locked and unlocked with an electronically powered motorised knob.

Combining the 3KSplus locking system with an electronic locking system
Very often mechanical locking systems are used in combination with electronic access controls. This means that all different types of door can be equipped with suitable security technology, according to their specific level of protection.

Mechanical emergency lock for electronic locking systems
Due to the robustness and stability of mechanical locking systems, they are often required for use in emergency service buildings (e.g. fire brigade) as mechanical emergency locks (overlocks) for electronic systems.
