The BEST 1A1L1KS473KS800 is a standard 7-pin key blank cut to the L keyway profile, designated KS473. Key blanks in this family are used by locksmiths and security technicians to produce bitted keys for BEST interchangeable core (IC) and conventional cylinder lock systems. This blank ships as a single unit and is compatible with BEST's established masterkey and interchangeable core platforms. It measures approximately 4.6 inches in length, 3.3 inches in width, and 2.7 inches in height in its packaged form, and weighs 0.03 pounds.
This key blank is intended for use in commercial and institutional facilities where BEST lock cylinders are installed. Typical applications include office buildings, schools, hospitals, and government facilities that rely on BEST masterkey systems. The KS473 L keyway profile is a controlled keyway, meaning duplication is restricted to authorized BEST distributors and dealers. Security-conscious facility managers and locksmiths specify this blank when producing keys for existing BEST 7-pin cylinders on a site.
Designed as an OEM-style replacement blank for BEST 7-pin L keyway (KS473) lock cylinders used in commercial masterkey and interchangeable core systems.
Key cutting should be performed by a licensed locksmith or authorized BEST dealer using a properly calibrated key-cutting machine. Verify the target cylinder's keyway profile and pin count before cutting to avoid producing an unusable key. Handle blanks carefully to avoid bending or surface damage that could affect cutting accuracy or cylinder operation.
