Kwikset 400T-3 Tylo Knob Entry Door Lock Bright Brass

Product Description

The KWIKSET 400T-3 is a keyed entry knob lock designed for residential exterior door applications. The Tylo knob style pairs with a 6AL latch and RCS strike plate, providing a complete entry set ready for installation. Finished in Bright Brass, this lock set is sold keyed different, meaning each unit ships with its own unique key cut — standard for multi-door or new-construction installations where master-keying is not required. The package ships as a single unit and weighs 1.05 pounds. This is a mechanical pin-tumbler knob lock intended for installation by a locksmith, general contractor, or experienced handyman.

The 400T-3 is suited for residential entry doors in single-family homes, apartments, and light-duty commercial applications where a knob-style entry lock meets local code. The keyed-different configuration is typical for builder-grade installations and replacement projects. The included 6AL latch and RCS strike simplify installation by eliminating the need to source additional hardware. The Bright Brass finish coordinates with standard residential door hardware across a wide range of door styles.

Installation Notes

Installation is performed by a locksmith, general contractor, or qualified handyman following door hardware manufacturer guidelines and any applicable local building codes. Confirm the door bore diameter and backset measurement before installation to ensure proper latch and knob alignment. Disconnect any wired door hardware and ensure the door is in a stable, open position during installation. Do not overtighten mounting screws, as this can bind the knob mechanism.
