Kaba Ilco Corp 1646R Usps Mailbox Key Blank 10 Pack

Product Description

The KABA ILCO CORP 1646R is a nickel plated brass key blank cut to the reverse profile used for USPS mailbox locks. This blank is designed for locksmiths and key cutting shops that service postal mail receptacles requiring the standard USPS reverse keyway. The nickel plated brass construction provides corrosion resistance and durability suitable for outdoor mail applications. Each unit is sold in a package of 10 blanks, making it practical for shops that regularly service postal lock cylinders. This is an uncut blank and requires professional key cutting equipment to duplicate or originate a key.

This key blank is used in residential and multi-unit residential settings where USPS-approved mailbox hardware is installed. It is commonly stocked by locksmith shops, hardware distributors, and property management maintenance teams that handle mail receptacle rekeying or key duplication for tenants and homeowners. The reverse profile is specific to postal lock applications and is not interchangeable with standard residential keyways.

Installation Notes

Key blank cutting and duplication should be performed by a licensed locksmith using equipment compatible with the reverse profile keyway. Always verify the keyway profile against the target lock cylinder before cutting. Do not attempt to cut this blank on equipment calibrated for standard residential profiles, as the reverse geometry requires a correctly configured key machine.
