Kwikset 665-26DS.DS – Frequently Asked Questions

1) Does the Kwikset 665 SmartKey deadbolt fit a 2-3/8 inch or a 2-3/4 inch backset door prep?
Both. The RCAL latch on the Kwikset 665 is adjustable from 2-3/8 inches to 2-3/4 inches, so it drops into either of the two standard residential bores without a separate part. Those are the only two backsets you normally see on a drilled residential door, so no measuring beyond the cross-bore is needed.
2) Is the Kwikset 665 keyed on both sides, or does it have a thumbturn inside?
Key both sides. The 665 is a double cylinder deadbolt, so there is no thumbturn to throw the bolt from the interior and you need a key to get out. That is the reason people specify it on doors with glass beside or in them, and it is also why many jurisdictions restrict double cylinder bolts on required egress doors. If you want a thumbturn inside instead, a single cylinder deadbolt is the part to order.
3) Can I key the Kwikset 665 to match the Schlage keys already used across my rental units?
Yes, if those keys are SC1. SmartKey Security on the 665 lets you re-key the cylinder yourself in seconds, and it is offered in either the Kwikset KW1 keyway or the Schlage SC1 keyway, so you can pick the one that matches the rest of your buildings. Both cylinders on a double cylinder bolt take the same key. For a property manager standardizing a fleet, that means one key across mixed Kwikset and Schlage-keyed doors.
4) Is the Kwikset 665 deadbolt rated for commercial or institutional use?
No. It carries ANSI/BHMA Grade 3 certification and is a residential deadbolt. For a commercial opening, an apartment corridor door, or anything in a school or healthcare facility, step up to Grade 1 or Grade 2. Comparable double cylinder options we carry include the Design Hardware D1 Series, which is Grade 1 extra heavy duty for 1-3/4 inch doors, the Dexter DB1000 Series Grade 1 double cylinder for 1-3/8 to 1-7/8 inch doors, and the Dexter DB2000 Series Grade 2 double cylinder for 1-3/8 to 1-3/4 inch doors.
5) Is a double cylinder deadbolt the right choice for a rental unit entry door?
Usually not. A key-both-sides bolt like the 665 means a tenant cannot exit without a key, which many local codes prohibit on a dwelling unit egress door. It makes sense on a door with adjacent glass where a thumbturn could be reached from outside, and on storage or utility doors. For standard unit entries, a cylinder x thumbturn deadbolt is the safer spec: the Dexter DB2000 single cylinder (Grade 2, 1-3/8 to 1-3/4 inch doors) or the Cal-Royal ED500 (Grade 3, adjustable backset, 1-3/8 to 1-3/4 inch) both cover that.
6) Will a Kwikset 665 work on a fire rated commercial door, or do I need something else?
The Kwikset KWI-665-S is a residential deadbolt carrying ANSI/BHMA Grade 3. For a fire rated opening, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and a fire rating, and the Hager 3214 is the Grade 2 double cylinder version, both for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
7) I need a thumbturn on the inside instead of a second key cylinder - what should I order?
The Kwikset KWI-665-S is operated by key on both sides, so it is not the choice where egress without a key is needed. Cylinder x thumbturn alternatives include the Cal-Royal ED500, a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, the Cal-Royal LSD Grade 3 with an ADA ergonomic thumbturn, and the Dexter DB2000-SCT, a Grade 2 single cylinder deadbolt for 1-3/8 inch to 1-3/4 inch doors. For heavier duty, the Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset.
8) What is the closest Grade 3 double cylinder deadbolt to the Kwikset 665 from another brand?
The Kwikset KWI-665-S is a Grade 3 deadbolt keyed on both sides. Matching that grade and function, the Callan Model 210S is a Grade 3 double cylinder deadbolt, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt with a 1-3/8 inch to 2 inch door thickness range. Where the 665 differs is SmartKey Security, which lets the lock be re-keyed on site and works with either the Kwikset KW1 or Schlage SC1 keyway.
9) Which deadbolts take an interchangeable core instead of the Kwikset SmartKey cylinder?
The Kwikset KWI-665-S uses SmartKey cylinders keyed to KW1 or SC1, not a small format interchangeable core. For an SFIC or less-core opening, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for 1-3/8 inch to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single deadbolt for interchangeable core with a 2-3/4 inch backset, and the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
10) What finishes does the Kwikset 665 round deadbolt come in?
Seven: Satin Nickel, Venetian Bronze, Satin Chrome, Bright Chrome, Bright Brass, Antique Brass, and Matte Black. If you are matching existing units, Satin Nickel and Venetian Bronze are the two that pair with most current residential trim, and Matte Black with contemporary packages. The trim on the 665 is round, so square rosette hardware elsewhere on the door will not match in shape even in the same finish.
11) What comes in the box, and do I need anything else to install it?
The kit includes both keyed cylinders, the RCAL adjustable latch with round corner faceplate, dual round corner strikes, the 5303 full lip strike, and two keys. A screwdriver is all the tooling required on a door that is already bored for a deadbolt. If the door has no deadbolt prep yet, you will need a boring jig and chisel work for the cross bore, edge bore and jamb pocket, which is not included.
12) I want a round double cylinder deadbolt but not SmartKey. What else is there?
Several. The Callan Model 210S is a Grade 3 double cylinder deadbolt, and the Delaney LU Series is a Grade 2 double cylinder in Stainless Steel (US32D). On the decorative side, the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt and the Baldwin Estate 8011 give you a round double cylinder in heavier brass trim. None of those offer user re-keying, which is the trade-off against the 665.
13) Is there a double cylinder deadbolt with a square rose instead of the round trim on the Kwikset 665?
The Kwikset KWI-665-S uses round trim with round corner latch faceplates. If the opening calls for square trim on a keyed-both-sides deadbolt, the Baldwin Reserve DC.CSD is a double cylinder contemporary square deadbolt; its round counterpart is the Baldwin Reserve DC.CRD. The Emtek 8323 Modern Disc is a brass double cylinder deadbolt in a disc trim style.
14) Is the Arrow 460 or the Baldwin 8BR0618001 a substitute for the Kwikset 665 deadbolt?
Neither is a deadbolt lock. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, and the Baldwin Reserve 8BR0618001 is a deadbolt spacer. The BEST 8T is a T Series tubular deadbolt tube component rather than a complete lock. The Kwikset KWI-665-S is a complete key-both-sides deadbolt that ships with a latch, keys, and a round deadbolt strike.
15) If I want keyless code entry instead of the Kwikset 665's keyed cylinders, what are the options?
The Kwikset KWI-665-S is a mechanical deadbolt operated by key on both sides. For code or credential entry, the Codelocks CL200 is a light duty surface deadbolt with key override, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
16) My door is thicker than 1-3/4 inches - which deadbolt covers it?
For thicker stock, the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt rated 1-3/8 inch to 2 inch, and the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch. The Dexter DB1000-DCT Grade 1 double cylinder deadbolt covers 1-3/8 inch to 1-7/8 inch. The Kwikset KWI-665-S latch is adjustable for 2-3/8 inch and 2-3/4 inch backset preparations.
17) What do I use where only one face of the door can be bored, unlike the Kwikset 665?
The Kwikset KWI-665-S requires cylinders on both faces of a standard cross-bore preparation. For a single-face application, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt. If the inside face needs a thumbturn with no keyway outside, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate by thumbturn for 1-3/8 inch to 1-3/4 inch doors.
18) Does the 1 inch throw on this Kwikset deadbolt actually add security over a cheaper bolt?
It matters on the jamb. A 1 inch bolt reaches deep enough into the strike to resist spreading the frame, which a shorter throw does not, and the included full lip and round strikes spread the load on the jamb face. Pair it with long screws into the stud and the bolt engagement, not the lock body, is what carries a kick attempt. The SmartKey mechanism also adds resistance to picking and bumping.
