WILKA 1400 K423 Euro Cylinder Lock EN 1303 Class C Security Card 40/55mm Nickel Matte

Product Overview

The WILKA 1400 K423 cylinder lock insert is a high-security profile cylinder designed for use in commercial and residential doors requiring advanced protection. It complies with EN 1303:2015 standards and is certified to burglary resistance class C (WQ-ITB), ensuring suitability for projects with strict safety requirements. Its construction features hardened steel and brass elements with a nickel-matte finish, achieving corrosion resistance grade C and a tested durability of over 100,000 operating cycles. Fire-door suitability is included in the certification scope.

A major differentiator of this cylinder is the requirement for key duplication exclusively via an included security card and authorized service partners, providing control over unauthorized key copying in managed facilities. This is a significant risk reduction for property managers, institutional buyers, and B2B customers in need of restricted access. Particularly recommended for projects where auditability and controlled key management are crucial, such as multi-tenant buildings, banks, and critical infrastructure.
