Product Description

The KWIKSET 159SQT-26DS.STRKP is a Halifax series double cylinder deadbolt featuring a square rose design and SmartKey Security rekeying technology. This deadbolt ships as a complete installation kit that includes a 6AL latch and a strike pack containing square corner, round corner, and 5303 round corner full lip strike plates. Finished in satin chrome (26DS), it is suited for exterior door applications where keyed access is required from both sides. The SmartKey cylinder allows field rekeying without removing the lock from the door, a feature frequently used by residential locksmiths and door hardware installers to match keys across multiple locks on a property.

The included strike pack provides hardware for multiple door frame conditions, covering both square corner and round corner mortise cutouts. The satin chrome finish coordinates with standard residential door hardware. Sold individually, with a case quantity of 12 units for multi-unit or contractor purchases.

Installation Notes

Double cylinder deadbolts are installed by licensed locksmiths or experienced door hardware installers and may be subject to local building and fire code restrictions — verify compliance before installation. Confirm door thickness and backset measurement before ordering the latch. Select the appropriate strike plate from the included strike pack based on the door frame corner condition. Secure all strike plate fasteners fully into the door frame framing, not just the jamb casing, per standard residential security practice.
