WILKA 1400 K423 Cylinder Lock EN 1303 Class C Security Card 35/60mm Nickel Matte

Product Overview

The WILKA 1400 K423 35/60 nickel matte cylinder lock is designed for high-security door installations in residential and commercial environments, especially where enhanced mechanical protection and durability are required. Certified to EN 1303:2015 and WQ-ITB security class C, its paracentric profile and 6-pin mechanism provide elevated resistance against manipulation and unauthorized access. Approved for use in fire-rated doors, it is suitable for specification-driven procurement with strict security and longevity requirements.

A distinguishing feature of this model is its security-coded key duplication system, which mandates that additional keys can only be made upon presentation of an included security card at authorized service centers. This eliminates the risk of unauthorized key copying and supports regulated access control, making this cylinder lock ideal for multi-tenant buildings, offices, and facilities where key management is a critical operational factor.
