Silca BK1 Key Blank Steel Compatible with BKS Hörmann Yale Cross-Reference Codes

Product Overview

The Silca BK1 key blank is a steel key used for duplicating mechanical keys in professional locksmith shops and key cutting outlets. Compatible with keyways from several major manufacturers including BKS, Hörmann, and Yale, it is intended for commercial and residential lock systems where precise duplication is essential. The key blank features dimensions A-27.5 mm, B-2.2 mm, C-8.6 mm, and D-58.5 mm, supporting consistent compatibility with a wide range of locks.

A primary value of the Silca BK1 is its cross-reference compatibility with many alternative part numbers and manufacturers' codes, enabling locksmiths and distributors to streamline inventory and meet replacement needs without sourcing dozens of separate SKUs. This reduces procurement risks associated with old or legacy part numbers and is particularly efficient for wholesalers, key cutters, or regional distributors handling multiple lock system brands.
