Kwikset KWI-159SQT Halifax Square Rose Double Cylinder Deadbolt SmartKey with 6AL Latch and STRKP Strike Pack

The Halifax square rose deadbolt ships with a latch that adjusts between a 2-3/8 inch and a 2-3/4 inch backset, which covers both standard residential bore preps, so an existing deadbolt hole works without redrilling. Two interchangeable faceplates come in the box, round corner and square corner, so it drops into either style of edge mortise. Install is screwdriver only.

Double cylinder means a key operates the bolt from both the outside and the inside; there is no thumbturn. That is the reason people put it on a door with glass sidelites or a glazed panel, since breaking the glass and reaching through gets you nowhere without a key. The trade-off is egress: anyone inside needs a key to get out, so it is not the right choice on a bedroom-side or primary egress door where a key may not be at hand. If you want a thumbturn inside instead, a single cylinder deadbolt such as the Dexter DB2000 Grade 2 is the cylinder-by-thumbturn version.

The bolt throws a full 1 inch, and a full lip round deadbolt strike is included in the pack. A 1 inch throw needs a strike box bored deep enough to take it, so if you are reusing an old strike prep cut for a shorter bolt, plan on deepening the pocket in the jamb. Fitting the supplied round strike is the cleaner route on a jamb that already has a round deadbolt strike cutout.

Yes. Keying is chosen at order time, keyed different or keyed alike, at no charge, and there is an optional key code field if you need the locks cut to a code you already carry. Each lock ships with two keys. For a landlord or property manager standardizing a building, ordering keyed alike across the units' common doors is the way to do it. The lock uses SmartKey, so a cylinder can also be rekeyed to a new key later without pulling the lock off the door.

Halifax is a residential product, part of Kwikset's Signature Series, meant for exterior doors on homes and light multi-family. For a commercial opening where a specification calls out a grade, look at the commercial deadbolts instead: the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt, and the Hager 3214 is a Grade 2 double cylinder for 1-3/8 to 1-3/4 inch doors. Those are the ones to quote when a drawing or a facility standard is driving the purchase.

The Baldwin Reserve Contemporary Square Deadbolt is a double cylinder deadbolt with square trim, and the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt. The Kwikset 159 Halifax is keyed on both sides with a square rose in Venetian Bronze, Satin Nickel, Satin Chrome, Bright Chrome and Matte Black. The Bravura 310SC is a cylinder x thumbturn function, so it is keyed outside and turned by hand inside rather than keyed both sides.

The Kwikset 159 Halifax is a residential deadbolt. For a graded double cylinder, the Design Hardware D1 Series is Grade 1, extra heavy duty, double cylinder, for 1-3/4 inch doors; the Dexter DB1000 Series is a Grade 1 double cylinder for 1-3/8 to 1-7/8 inch doors; and the Hager 3214 is a Grade 2 double cylinder with a Schlage C keyway for 1-3/8 to 1-3/4 inch doors and carries a fire rating.

A double cylinder deadbolt like the Kwikset 159 Halifax takes a key on both sides. If the inside face does not need a key, a cylinder x thumbturn deadbolt turns by hand from inside: the Dexter DB2000 Series is Grade 2 cylinder x thumbturn for 1-3/8 to 1-3/4 inch doors, the Cal-Royal CB160 is Grade 2 with a tamper-resistant cylinder guard, and the Cal-Royal ED500 is Grade 3 with an adjustable backset for 1-3/8 to 1-3/4 inch doors.

The Kwikset 159 Halifax latch adjusts for 2-3/8 to 2-3/4 inch backsets, which is the bore setback rather than the door thickness. Among double cylinder options, the Deltana 7312KA2 is a Grade 3 deadbolt rated for 1-3/8 to 2 inch doors, and the Dexter DB1000 Series double cylinder covers 1-3/8 to 1-7/8 inch. For thicker openings, the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 to 2-1/4 inch doors.

SmartKey lets you rekey the cylinder yourself in the doorway with the existing key and a rekey tool, no locksmith and no removing the lock from the door. For a property manager turning units, that is the difference between a service call per door and a two minute reset when a tenant moves out. Nothing else in the hardware changes, so the same lock carries from tenant to tenant.

Everything for the opening is in the pack: the 6AL adjustable latch, the strike pack with a full lip round deadbolt strike, two interchangeable faceplates, two keys and the mounting screws. A screwdriver is the only tool needed. Nothing separate to order unless you are adding a matching entry knob or lever alongside it.

No. The Halifax is a residential deadbolt, and keyed-both-sides on a commercial egress door raises a code issue in most occupancies. For a school or institutional opening, the Falcon D111 is a Grade 1 classroom function deadbolt with adjustable backset, and the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 to 2-1/4 inch doors. Those are built for the traffic and the specification.

No. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, a mounting component rather than a working lock. The Kwikset 159 Halifax is a complete keyed-both-sides deadbolt supplied with a 6AL adjustable latch, a full lip round deadbolt strike and two keys. The same distinction applies to the BEST 8T tubular deadbolt tube component and the Arrow 460 mortise lock strike, which are pieces of a lock rather than a lock.

The Callan Model 210S is a Grade 3 double cylinder deadbolt, the Delaney LU Series is a Grade 2 double cylinder in Stainless Steel US32D, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. The Baldwin Estates 8011 Contemporary is a 1-5/8 inch double cylinder in entrance function. The Kwikset 159 Halifax carries SmartKey, so the owner can rekey it themselves, and comes in five finishes including Matte Black and Venetian Bronze.

The Kwikset 159 Halifax operates by key from both sides. For a one-sided or non-keyed inside face, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, and the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside for 1-3/8 to 1-3/4 inch doors.

The Kwikset 159 Halifax is a mechanical deadbolt keyed on both sides and supplied with two keys. Electronic alternatives include the Delaney KP400, a Grade 2 electronic deadbolt with a programmable remote; the Codelocks CL2200, a medium duty electronic surface deadbolt in Brushed Steel; the Codelocks CL200, a surface deadbolt with key override; and the Dormakaba Saffire LX-D, an RFID electronic deadbolt with BLE and electronic lock override.

For classroom-function openings the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, the Falcon D211 is the Grade 2 medium duty equivalent, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder for 1-3/8 to 1-3/4 inch doors. The Kwikset 159 Halifax is a residential deadbolt keyed on both sides, offered keyed alike or keyed different.

They prep differently. The Emtek 2050 is a European mortise deadbolt with an integrated roller latch in a square trim, and the 2051 is the round version; both need a mortise pocket in the door edge. The Kwikset 159 Halifax uses a standard bored door preparation with a latch adjustable from 2-3/8 to 2-3/4 inch backset and installs with a screwdriver.

The Kwikset 159 Halifax uses SmartKey and ships with two keys, with keyed alike or keyed different selected at order. For an interchangeable core program, the Deltana CL200LAIC is a Grade 2 single deadbolt prepped for an interchangeable core with a 2-3/4 inch backset, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.

Five finishes: Venetian Bronze, Satin Nickel, Satin Chrome, Bright Chrome and Matte Black. Matte Black and Satin Nickel are the two that most often need to match adjacent levers and entry sets already on a building's doors, so pull a sample against what is hung before committing a whole run.

The Halifax 159SQT uses a square rose, so the escutcheon behind the cylinder is squared off, which suits contemporary and modern-trim doors. If the rest of the openings carry round trim, the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt is a round-rose double cylinder alternative, and Baldwin also lists a contemporary square version if you want to stay square in a different brand.

Microban antimicrobial product protection is built into the hardware surface, which Kwikset states keeps the door hardware 99.9 percent cleaner than unprotected surfaces. It is a surface treatment on the trim, not a substitute for cleaning protocol, and it is a residential-line feature rather than a healthcare code item.
