WILKA 1400 K423 Cylinder Lock EN 1303:2015 Class C 45/45mm Security Card Nickel Matte

Product Overview

WILKA 1400 K423 is a class C cylinder lock insert designed for security doors in residential and commercial premises. Built with a 6-pin mechanism and hardened brass and steel pins, it is certified to EN 1303:2015, resistance class D, and offers tested durability over 100,000 operating cycles. The paracentric profile and anti-picking mushroom pins maximize protection against manipulation, while corrosion resistance is rated C, suitable for fire-rated installations and demanding environments.

The defining feature of this SKU is key duplication control via security card: keys can only be replicated at authorized service points on presentation of the supplied security card, mitigating unauthorized access risk for facility owners and property managers. This provides compliance for regulated access projects and makes it ideal for bulk procurement in multi-tenant residential, office complexes, and facilities where strict key control is required.
