Kwikset 405DNL-15S Dorian Lever Entry Lock Smartkey Satin Nickel

Product Description

The KWIKSET 405DNL-15S is a lever-style entry door lock designed for residential exterior door applications. It ships as a complete set including the Dorian lever handle, a 6AL latch, and an RCS strike plate, giving installers everything needed for a full door prep in a single package. The satin nickel finish provides a clean, neutral appearance suited to a wide range of door hardware styles. A core feature is SmartKey Security, a re-keying system that allows the lock cylinder to be rekeyed in seconds using a SmartKey tool and a new key — no lock removal required. The unit weighs 1.76 pounds and measures 6.8 inches long by 5.7 inches wide by 3.1 inches tall.

This lock is intended for residential entry door installations where a keyed lever handle is required. Typical applications include front entry doors, side entry doors, and back doors on single-family homes and multi-unit residential buildings. The complete kit format — lever, latch, and strike — makes it well suited for new construction, door replacement, or hardware upgrade projects where all hardware components need to match. The SmartKey re-key capability is especially useful for property managers and landlords who need to change key access between occupants without replacing the hardware.

Compatibility

Designed as an OEM-style replacement or new-installation lever entry lock for standard residential door preps. Specific door and frame compatibility should be confirmed against door prep dimensions and backset requirements before installation.

Installation Notes

Installation is typically performed by a licensed locksmith, general contractor, or experienced finish carpenter. Before beginning, ensure the door is closed and confirm the door prep backset and cross-bore dimensions match the lock specifications. Follow local building codes for residential entry door hardware, and verify that the strike plate mortise depth is appropriate for the RCS strike included. Do not overtighten mounting screws, as this can affect latch and lever operation.
