Best 1A1TD1KS473KS800 7 Pin Td Keyway Key Blank KS473

Product Description

The BEST 1A1TD1KS473KS800 is a standard 7-pin key blank cut to the TD keyway profile, used in BEST interchangeable core and masterkey locking systems. Key blanks like this one serve as the uncut starting point for lock technicians and locksmiths who need to duplicate or originate keys for BEST-keyed cylinders. The KS473 designation identifies the specific keyway series. At 3.6 pounds per case unit and compact package dimensions of 4.6 inches by 3.3 inches by 2.7 inches, this blank ships as a single unit and is sized for standard key-cutting equipment compatible with BEST keyways.

This key blank is intended for use in commercial and institutional access control applications where BEST interchangeable core systems are installed. Typical environments include schools, hospitals, government facilities, and commercial office buildings that rely on BEST masterkey systems. Locksmiths and licensed security hardware technicians order this blank when originating or duplicating keys for cylinders configured with the TD keyway. It is sold as a single blank and is intended for professional key-cutting operations, not for consumer self-service duplication.

Installation Notes

Key origination and duplication on restricted keyway blanks should be performed only by licensed locksmiths or authorized security hardware technicians.

Restricted keyway blanks may be subject to key control agreements — confirm authorization before duplicating.
