Kwikset 665-26DS.STRKP – Frequently Asked Questions

1) Does the Kwikset 665 deadbolt take a key on the inside too, or is there a thumbturn?
Keyed both sides. The 665 is a double cylinder deadbolt, so there is a cylinder inside and out and you need a key to retract it from within the room. That matters on doors with glass beside or in them, where a thumbturn can be reached through a broken pane. It also means anyone inside needs a key to get out, so check your local egress rules before putting one on a primary exit. If you want a thumbturn inside instead, a single cylinder deadbolt is the one to order.
2) Which keyway does the Kwikset 665 SmartKey deadbolt use, and can I key it to match my other locks?
It ships on the Kwikset KW1 keyway, and the SmartKey re-key technology works with either the Kwikset KW1 or the Schlage SC1 keyway option. SmartKey lets you re-key the cylinder yourself in seconds with the learn tool and an existing key, so a landlord turning over a unit can bring the new deadbolt onto the same key as the rest of the door hardware without pulling a cylinder or calling a locksmith.
3) What grade is the Kwikset 665 deadbolt, and is it rated for commercial use?
ANSI/BHMA Grade 3, and it is catalogued for residential use. Grade 3 is the residential tier, so for an apartment entry, a rental turnover, or a single family exterior door it is the right class of lock. For a commercial opening or a high traffic institutional door, step up: the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt, and the Dexter DB1000 Series double cylinder is also Grade 1.
4) Will the Kwikset 665 latch into my existing strike plate?
The deadbolt throws a full 1 inch, which is what reaches through the jamb and into the framing on a standard strike. A round corner strike is included in the box. If the old strike in your jamb has square corners, use the mortise you have and swap only if the corner radius does not match; the round corner faceplate on the latch itself means the door edge mortise also needs to be round cornered, or you square off the corners of the new plate to sit in an existing square mortise.
5) What is a commercial-grade double cylinder deadbolt to use instead of the Kwikset 665 on a heavier traffic opening?
The Kwikset 665 is a Grade 3 residential double cylinder deadbolt with SmartKey re-keying. For a heavier duty opening, the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt rated extra heavy duty for 1-3/4 inch doors, and the Dexter DB1000 is a Grade 1 double cylinder deadbolt covering 1-3/8 to 1-7/8 inch doors. Both are keyed both sides like the 665 but carry a higher ANSI/BHMA grade.
6) Which double cylinder deadbolt is the closest Grade 3 equivalent to the Kwikset 665?
The Callan Model 210S is a Grade 3 double cylinder deadbolt, matching the 665 on both grade and key-both-sides function. The Deltana 7312KA2 is also a Grade 3 double cylinder deadbolt and covers doors from 1-3/8 to 2 inches. Neither offers the SmartKey user re-key feature the Kwikset 665 provides on the KW1 keyway.
7) We need a thumbturn inside instead of a second key cylinder - what replaces the Kwikset 665?
The Kwikset 665 is operated by key on both sides. If egress by thumbturn is required, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn. The Dexter DB2000 single cylinder is a Grade 2 cylinder x thumbturn option for the same door thickness range.
8) Does the Hager 3214 work as a substitute for the Kwikset 665 double cylinder deadbolt?
The Hager 3214 is a Grade 2 double cylinder deadbolt for 1-3/8 to 1-3/4 inch doors and is fire rated, so it suits openings where a fire rating is called for. The key difference is keying: the Hager 3214 uses the Schlage C keyway, while the Kwikset 665 is built around SmartKey on the KW1 keyway. If the building is keyed to Kwikset KW1, the 3214 will not key alike with it.
9) For a school or institutional door, what deadbolt would I specify rather than the Kwikset 665?
The Kwikset 665 is a residential Grade 3 deadbolt. For institutional openings, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway, 6-pin cylinder, and a fire rating for 1-3/8 to 1-3/4 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty deadbolt with a UL 3-hour fire rated latch.
10) Is a double cylinder deadbolt the right choice, or should I use a single cylinder?
Pick the double cylinder where the door has glass in it or a sidelite within arm's reach of the lock, so an intruder breaking the glass still cannot turn the bolt. Pick single cylinder anywhere egress speed matters or where occupants will not reliably have a key on them. The Kwikset 665 is the keyed-both-sides version. If you decide you want a thumbturn inside instead, comparable single cylinder deadbolts we carry include the Cal-Royal ED500, which is also Grade 3 with an adjustable backset, and the Dexter DB2000 single cylinder in Grade 2.
11) What is SmartKey on this Kwikset deadbolt actually doing for me?
Two things. It is bump and pick resistant against the advanced break-in techniques that defeat a conventional pin tumbler, and it lets you re-key the cylinder on the door in seconds with the existing key and the learn tool, rather than pulling the lock. For a property manager running unit turnovers, that is the whole argument: same lock stays on the door, key changes between tenants, no locksmith call.
12) I need a double cylinder deadbolt for a commercial or multifamily corridor door. What else do you carry besides the Kwikset 665?
The 665 is a Grade 3 residential lock, so for heavier duty go to a commercial double cylinder. The Design Hardware D1 Series is Grade 1, extra heavy duty, listed for 1-3/4 inch doors. The Dexter DB1000 double cylinder is Grade 1 and covers 1-3/8 to 1-7/8 inch doors. The Hager 3214 is a Grade 2 double cylinder on the Schlage C keyway for 1-3/8 to 1-3/4 inch doors, and it carries a fire rating. Delaney's LU Series double cylinder is Grade 2 in stainless steel US32D.
13) Does the Kwikset 665 come with keys and a strike, or do I need to order those separately?
Everything for the opening is in the clear pack: the deadbolt with cylinders on both sides, the adjustable round corner latch, the round corner deadbolt strike, and two keys. You supply the screwdriver. Nothing else is required unless your jamb needs a different strike lip or reinforcement.
14) Is the Baldwin Reserve DC.CRD round deadbolt the same thing as the Kwikset 665?
Both are double cylinder deadbolts with round trim, so they look similar on the door. The Baldwin Reserve DC.CRD is a contemporary round design in the Reserve line, while the Kwikset 665 is a Grade 3 residential deadbolt with SmartKey re-key technology, an adjustable 2-3/8 to 2-3/4 inch backset latch, and a 1 inch throw. Baldwin also offers the DC.CSD in a square rose if the trim shape needs to match square hardware.
15) What double cylinder deadbolt should I look at if the Kwikset 665 finish options do not match my other hardware?
The Kwikset 665 comes in satin chrome and satin nickel. If a stainless steel look is required, the Delaney LU Series is a Grade 2 double cylinder deadbolt in stainless steel US32D. For a solid brass decorative alternative, the Emtek 8323 Modern Disc is a brass double cylinder deadbolt.
16) The opening needs a deadbolt with no key outside - what do I use instead of the Kwikset 665?
The Kwikset 665 is keyed on both sides. For an exit-only opening, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside, for 1-3/8 to 1-3/4 inch doors. If only one side needs any hardware at all, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt.
17) Is there a keypad or electronic deadbolt alternative to the Kwikset 665?
The Kwikset 665 is a mechanical deadbolt keyed both sides. For keyless operation, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel. The Codelocks CL2210 is an electronic mortise deadbolt if the door is prepped for a mortise case rather than a tubular bore.
18) Can I substitute the Arrow 460 strike for the round corner strike that comes with the Kwikset 665?
No - they are different classes of part. The Kwikset 665 ships with a round corner deadbolt strike matched to its round corner faceplate latch. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, intended for a mortise lock case on a 1-3/4 inch door, not for a tubular residential deadbolt prep.
19) What deadbolt takes an interchangeable core instead of the Kwikset 665 SmartKey cylinder?
The Kwikset 665 uses SmartKey cylinders on the KW1 keyway, re-keyed by the owner. If the property is on an interchangeable core system, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core, and the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for 1-3/8 to 1-3/4 inch doors. Both are single cylinder, so they do not match the 665 key-both-sides function.
20) Which adjustable backset single cylinder deadbolts compare to the Kwikset 665 latch?
The Kwikset 665 latch adjusts from 2-3/8 to 2-3/4 inch backset to fit standard door preps. Comparable adjustable options include the Brinks Raleigh E2401 round single cylinder deadbolt and the Brinks Mendocino E2402 square single cylinder deadbolt, both with 4-way adjustable backset, and the Cal-Royal ED500, a Grade 3 single cylinder deadbolt with adjustable backset. All three are cylinder by thumbturn rather than keyed both sides.
21) What finishes does the Kwikset 665 double cylinder deadbolt come in?
Two: Satin Chrome and Satin Nickel. Satin Nickel is the warmer of the two and is the common match for residential entry sets; Satin Chrome reads cooler and greyer. If you are standardizing a building, pick one and keep the whole fleet on it, since these are the only two offered on the 665 round double cylinder.
