Product Description

The BEST 1A1E1KS473KS800 is a standard 7-pin key blank cut to the KS473 keyway profile and designed for use with BEST interchangeable core (IC) locking systems. This blank serves as the starting point for producing operational keys in facilities that rely on BEST IC hardware for access control. It is compatible with E keyway configurations and is suited for use by locksmiths, facility security technicians, and institutional maintenance teams managing large-scale masterkey systems. The blank measures 4.6 inches in length and ships as a single unit.

This key blank is used in commercial and institutional settings where BEST interchangeable core cylinders are installed, including schools, hospitals, government buildings, and corporate campuses.
