Product Overview

WILKA 1400 K423 40/45 double-sided cylinder lock provides high-security access control for residential and commercial doors, certified to EN 1303:2015 and WQ-ITB class C for burglary resistance. It features a 6-pin mechanism with hardened steel and brass pins, nickel-plated for durability, and achieves the maximum EN 1303 rating for manipulation resistance (level 6), cycle durability (100,000 cycles), and corrosion resistance (C).

The key feature distinguishing this model is its paracentric key profile, which significantly resists picking and unauthorized opening methods. Paired with a security card-based duplication restriction, it eliminates unauthorized key copying risk for property managers and security-conscious facilities.
