Kwikset 740A-3S Abbey Knob Entry Lock Smartkey Bright Brass

Product Description

The KWIKSET 740A-3S is a keyed entry door knob featuring SmartKey Security re-keying technology in a Bright Brass finish. It ships as a complete entry set, including a 6AL latch and RCS strike plate, making it ready for standard residential door installation. The Abbey knob style suits traditional and transitional door hardware aesthetics. SmartKey Security allows the cylinder to be re-keyed in seconds using the SmartKey tool, eliminating the need to replace the entire lockset when key control is required. The assembly is sold as a single unit and fits standard residential entry door prep.

The 740A-3S is intended for residential exterior entry door applications where a keyed knob is specified. It is suited to new construction, remodel, and lock replacement projects on standard 2-3/8 inch or 2-3/4 inch backset doors. The included 6AL latch and RCS strike reduce the need for separate hardware procurement. This product is appropriate for single-family homes and light commercial residential applications where an entry-function knob is required. Installation is typically handled by a locksmith, carpenter, or general contractor, and is also within range for experienced DIYers.

Installation Notes

Installation is performed by a locksmith, finish carpenter, or qualified contractor following the manufacturer instructions included with the unit. Before replacing an existing lockset, confirm the door bore diameter and backset measurement match the requirements of the 740A-3S. Standard installation tools include a screwdriver and, for new doors, a hole saw and boring jig. Do not force the latch or strike alignment — adjust the strike plate position as needed to ensure proper latch engagement and door security.
