WILKA 1400 K423 Euro Cylinder 40/50mm EN 1303:2015 Class C Controlled Duplication

Product Overview

WILKA 1400 K423 40/50 nickel matt is a high-security euro profile cylinder insert for door locks, certified to EN 1303:2015 with burglary resistance class C. Primarily used in residential and commercial exterior doors where elevated security is required, the cylinder features a 6-pin mechanism, drill-resistant hardened steel and brass pins, and a paracentric key profile that provides top manipulation resistance. It is suitable for environments that demand durable and tamper-resistant locking solutions, including fire-rated doors.

The exclusive security feature for this model is the controlled key duplication via an included security card, which ensures that replacement keys can only be made at authorized service points. This eliminates unauthorized key copying risk, a frequent procurement concern for property managers and security-conscious B2B buyers. Especially recommended for facility owners, building managers, and institutional projects where certified, traceable key systems are mandatory.
