Kaba Ilco Corp 1640 Key Blank Nickel Plated Brass Larson Door

Product Description

The KABA ILCO CORP 1640 is a nickel plated brass key blank cut to the LD2 keyway profile for use with Larson door locks. Key blanks serve as the uncut starting point for duplication or original key cutting — a locksmith or hardware technician cuts the blank to match a specific bitting, producing a working key. The nickel plated brass construction resists corrosion and provides the dimensional stability required for clean, accurate cuts. This blank is sold in a package of 10 units, making it practical for shop stock or service van inventory.

This blank is suited for residential and light commercial applications where Larson door hardware is installed. Larson storm and entry door locks use the LD2 keyway, and this blank covers that profile directly. Locksmiths, hardware store key cutting counters, and property maintenance technicians are the primary users. The 10-piece package quantity supports bulk cutting for multi-unit residential properties or ongoing service accounts.

Installation Notes

Key cutting should be performed by a qualified locksmith or trained hardware technician using a properly calibrated duplicating or code-cutting machine. Verify the keyway profile matches the target cylinder before cutting. Test the cut key in the lock cylinder before returning hardware to service. Always follow applicable locksmithing trade standards and local licensing requirements where applicable.
