It is suited to facilities that operate BEST cores on the KS473 key section and require field-cut duplicates or new keys for expanding an existing masterkey hierarchy.

This key blank is used in commercial and institutional access control applications where BEST interchangeable core hardware is installed. Typical environments include schools, hospitals, government facilities, and commercial office buildings that rely on BEST masterkey systems.

Installation Notes

Key cutting should be performed by a licensed locksmith or qualified security technician using a code-cutting or duplicating machine calibrated for the correct key section. Confirm the keyway profile and pin depth specifications match the target core before cutting. Do not attempt to force an incorrectly cut or mismatched blank into a lock core, as this can damage the core's pins and void service agreements. Always verify masterkey system records before issuing new cuts to maintain key control integrity.
