Kwikset 158SQT-15S.STRKP Halifax Deadbolt Smartkey Satin Nickel

Product Description

The KWIKSET 158SQT-15S.STRKP is a single cylinder deadbolt featuring a Halifax square rose design with SmartKey Security rekeying technology. Designed for residential exterior door applications, this deadbolt ships as a complete assembly including a 6AL latch and a strike pack containing square corner, round corner, and 5303 round corner full lip strike plates. The Satin Nickel finish provides a clean, neutral appearance suited to a wide range of door hardware configurations. Licensed locksmiths, carpenters, and general contractors install this type of hardware during new construction, renovation, or security upgrade projects.

This deadbolt is intended for residential exterior door installations where a keyed single cylinder lock is required. The included strike pack covers multiple door frame configurations, eliminating the need for separate strike plate orders on most standard residential installations. The SmartKey cylinder allows field rekeying without removing the lock from the door, which is a practical advantage for property managers and contractors handling multiple units. The KA3 keying designation indicates the lock ships keyed alike in sets of three.

Installation Notes

Installation is performed by a licensed locksmith, finish carpenter, or qualified contractor following local building codes. Before installation, confirm door thickness and backset measurements match the latch included in the kit. Disengage all power to any adjacent electronic hardware and ensure the door is stable before drilling or chiseling for strike plate seating. Do not overtighten mounting screws, as this can cause cylinder binding and affect SmartKey rekeying function.
