Kwikset 258SQT-4S.STRKP Smartkey Deadbolt Satin Brass

Product Description

The KWIKSET 258SQT-4S.STRKP is a single cylinder deadbolt featuring SmartKey Security re-keying technology, designed for residential exterior door applications. The Downtown Square collection offers a contemporary, low-profile trim style. This deadbolt ships as a complete installation package, including a 6AL latch and a Strike Pack that contains square corner, round corner, and 5303 round corner full lip strike plates. The hardware is finished in Satin Brass and is intended for installation by locksmiths, general contractors, or experienced residential door hardware installers. SmartKey technology allows the cylinder to be re-keyed in seconds without removing the lock from the door.

This deadbolt is suited for residential entry doors where a contemporary square trim profile is specified. The included strike pack gives installers flexibility to match existing door frame mortise conditions — square corner or round corner — without sourcing additional hardware separately. The Satin Brass finish coordinates with matching lever and knob sets in complementary Kwikset collections. KA3 keying designation indicates the lock is keyed alike in a set of three, reducing the number of keys a homeowner carries for multiple entry points.

Installation Notes

Installation should follow the door hardware manufacturer instructions and applicable local building codes. Ensure the door is closed and the existing lock is removed before fitting the latch and deadbolt assembly. Confirm the door backset and bore diameter match the hardware before installation. Strike plate selection from the included pack should be based on the existing door frame corner condition — square or round — to ensure proper bolt engagement and security.
