Kwikset 740H-3S Hancock Knob Entry Lock Smartkey Brass

Product Description

The KWIKSET 740H-3S is a Hancock-style keyed entry knob lock designed for residential exterior door applications. It ships as a complete entry set, including a 6AL latch and an RCS strike plate, so installers have everything needed for a standard door prep in one package. The lock features SmartKey Security, a re-keying technology that allows the cylinder to be re-keyed on-site without removing the lock from the door. Finished in Bright Brass, it suits traditional and transitional door styles. Installation requires a standard 2-1/8-inch cross-bore and a 1-inch edge-bore door prep.

This lock is intended for residential entry doors where a keyed knob is the specified hardware type. It is commonly installed on front entry, side, or back doors in single-family homes and low-rise residential buildings. The included 6AL latch accommodates standard door thicknesses, and the RCS strike is suitable for typical wood-frame door jambs. SmartKey re-keying makes this a practical choice for property managers, remodelers, and contractors who need quick, cost-effective keying changes between tenants or owners without calling a locksmith.

Installation Notes

Installation is performed by a licensed locksmith or qualified finish carpenter following standard door hardware procedures. Confirm door thickness and backset measurement before installation to ensure latch and strike alignment. Disengage any existing lock hardware and remove the door knob assembly before mounting the new unit. Re-keying via the SmartKey system should be completed using the SmartKey tool and a working key before the lock is put into service.
