Silca TR4 Steel Key Blank Compatible with TRIO-VING Dorma High-Durability

Product Overview

The Silca TR4 blank key is a steel key blank used for duplication or OEM production of security keys, compatible with lock systems from manufacturers such as TRIO-VING and Dorma. Professionals in locksmithing, hardware supply, and security system integration use these in commercial, residential, and institutional environments. Manufactured to precise dimensional standards, it matches multiple equivalent models including LOTUS TIG4 and ERREBI TV2.

Steel construction distinguishes the Silca TR4 from generic brass blanks, providing higher durability and resistance to wear during frequent use in high-traffic installations.
