The KWIKSET 665 26D SMT CP RCAL V2 is a double cylinder deadbolt lock featuring SmartKey rekey technology. It secures a door from both the interior and exterior using a keyed cylinder on each side, eliminating the thumbturn found on single cylinder units. This design is common in applications where glass panels or sidelights are located near the lock, reducing forced-entry risk. Licensed locksmiths, general contractors, and security-focused property owners install this hardware as part of residential entry door assemblies. The satin chrome finish (26D) provides a clean, low-sheen appearance suited to a range of door hardware styles.
This deadbolt is intended for residential entry doors where a double cylinder configuration is required. The SmartKey rekey feature allows the lock cylinder to be rekeyed in seconds using the SmartKey tool and a working key, without removing the lock from the door. This is practical for property managers and contractors who need to change key access between tenants or job phases without replacing hardware. The unit ships as a complete assembly ready for standard door prep.
Designed as an OEM-style replacement or direct installation deadbolt for standard residential door prep with a 2.125-inch backset and 1-inch bore hole pattern consistent with ANSI A115 door prep standards.
Installation is performed by a licensed locksmith, general contractor, or qualified installer following the manufacturer instructions included with the hardware. Standard residential door prep tools apply, including a hole saw and chisel for mortise pocket. Note that double cylinder deadbolts are subject to local building and fire codes in occupied residential dwellings - verify compliance with applicable IBC or local fire egress requirements before installation. Always test lock operation fully before completing the installation.
