The EVVA 3KS, with its revolutionary triple-curve system, represents state-of-the-art locking technology. Instead of conventional pins, the 3KS system uses special coding pins that glide along precise curved guides, providing exceptional protection against picking and other manipulation techniques. Long-term patent protection until 2035 prevents unauthorized key duplication. The particularly robust construction of high-quality nickel silver guarantees an extremely long service life, even under the harshest operating conditions. Copying an EVVA 3KS key is only possible at authorized EVVA partners and only upon presentation of the security card and corresponding identification. Despite its small size, the compact key head offers an ergonomic grip and can be conveniently carried on a keyring. Ideal for high-security areas in companies, public institutions, and demanding private applications.
