EVVA locking systems - 3KS+

3KSplus locking system from EVVA

Spring-free locking pin function with cam function

One advantage of the spring-free locking pin mechanism with cam function is that it offers a higher level of security than conventional cylinders. This is because the system is protected against so-called picking, i.e. attempts to open the cylinder by manipulating the pins. The cam milling on the reversible key also enables a greater number of variations, which allows individual adaptation to complex locking systems with overlapping hierarchies. Finally, the 3KS system from EVVA also offers the highest level of key duplication security, as duplicate keys may only be made by authorized bodies and are protected by patents and security cards.

Sophisticated locking technology offers maximum security

The sophisticated locking technology of the 3KS system from EVVA offers maximum security. There are twelve locking pins inside the cylinder, which are moved into certain positions by a total of six key cams by means of positive control. A total of four queries are made to ensure maximum security. This is a major advantage compared to other locking systems, where the coding of the key is often only checked once. In addition, the 3KS cylinder is secured with anti-drill protection on the housing and in the core. The pull and pull-off protection is provided by the carbide pressure slides.

Universally applicable

The 3KS plus from EVVA is used in public institutions, for example in universities and in the healthcare sector. Here, the high level of security ensures the protection of sensitive areas and data. However, the system can also be used in the private sector, for example in villas and luxury apartments where high security requirements apply. In general, the 3KS plus from EVVA is a sensible choice for anyone who requires high security standards and wants a flexible locking system with many variation options.

Convenience and high operating safety

In addition, the 3KS reversible lock offers a high level of operating safety. Simple and intuitive operation is possible thanks to the special cam function. The large number of variation options ensures that each key can be clearly assigned, even with complex locking systems. The grip surface and the key tip make it easier to insert and turn the key, which is particularly advantageous for older people and people with physical limitations. All in all, the 3KS reversible key not only offers a high level of safety, but also a high level of user convenience.

Product benefits

• 3KSplus is a reversible lock system that is characterized by a unique operating principle.
• Unlike classic locking systems, the locking elements in the 3KSplus cylinder are moved spring-free 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.
