Kwikset 159SQT-26S.STRKP Halifax Deadbolt Smartkey Chrome

Product Description

The KWIKSET 159SQT-26S.STRKP is a double cylinder deadbolt featuring a square rose design in a Bright Chrome finish. It is built around Kwikset SmartKey Security technology, which allows the lock to be rekeyed without removing it from the door. The assembly ships with a 6AL latch and a full strike pack that includes square corner, round corner, and 5303 round corner full lip strikes. This hardware is installed by residential locksmiths, door and hardware contractors, and experienced finish carpenters working on exterior door assemblies. The package dimensions measure 4.6 inches long by 4 inches wide by 3 inches tall, and the unit weighs 1.8 pounds.

The 159SQT-26S.STRKP is suited for residential exterior door applications requiring a double cylinder configuration, meaning a keyed cylinder is required on both the interior and exterior sides. This makes it a common choice for doors with glass panels where interior thumb-turn access would pose a security risk. The Halifax square rose profile fits standard door prep and pairs with matching Kwikset Halifax series handlesets and knobs for a coordinated look. The included strike pack accommodates varying door frame conditions, covering square corner, round corner, and full lip strike configurations in a single box.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware installer following the door manufacturer's prep specifications. Confirm door thickness and backset measurement before installation to ensure proper latch and strike alignment. Note that double cylinder deadbolts may be subject to local building or fire code restrictions regarding egress requirements — verify compliance with applicable codes before installation. The strike pack should be mortised flush to the door frame jamb for proper bolt engagement and security.
