Kwikset 660RDT-26DS.DS – Frequently Asked Questions

1) Will the Kwikset 660 deadbolt fit a door already bored for a 2-3/4 inch backset?
Yes. The 660 ships with an adjustable latch that sets to either 2-3/8 or 2-3/4 inches, so it drops into either of the two standard bore preps without a new hole. Set the latch before you put the bolt through the cross bore, and it covers essentially every standard residential door prep.
2) How does SmartKey rekeying work on the Kwikset 660 deadbolt, and which keyways does it take?
SmartKey lets you rekey the cylinder yourself in seconds with the tool and your new key, no cylinder removal and no locksmith. That is the reason property managers standardize on it: turn over a unit, rekey the bolt in place. The 660 SmartKey cylinder is available for the Kwikset KW1 keyway or the Schlage SC1 keyway, so you can bring it onto a building already keyed to either one. Two keys come with the lock.
3) Is the Kwikset 660 deadbolt strong enough for a commercial entrance?
It is a residential deadbolt, ANSI/BHMA Grade 3 certified, with a 1 inch throw. That is fine for apartment and single-family exterior doors. For a commercial opening or a high-traffic building entrance, step up: the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, and the Design Hardware D1 Series is a Grade 1 extra heavy duty deadbolt for 1-3/4 inch doors. If you want a middle option, the Arrow DBX61 is Grade 2 cylinder x thumbturn.
4) Will a 1 inch throw deadbolt reach my existing strike pocket?
The bolt throws a full 1 inch, which is what a standard deadbolt strike pocket is drilled for, so it will land in an existing deadbolt prep. The lock comes with its own full lip round strike, so if the old strike is a square corner plate you will either swap to the round one supplied or leave the existing strike in place and reuse the pocket. The latch faceplate is round corner as well.
5) Single cylinder or double cylinder deadbolt, which do I need?
The Kwikset 660 is single cylinder: key on the outside, thumbturn on the inside. Choose it wherever code allows a thumbturn, which is most residential entry doors, because occupants get out without hunting for a key. Where the door has glass within reach of the bolt and you want to stop someone breaking the glass and turning the thumbturn, you need a double cylinder instead, keyed both sides. Options for that include the Callan Model 210S Grade 3 double cylinder, the Dexter DB2000 double cylinder for 1-3/8 to 1-3/4 inch doors, or the Grade 1 Dexter DB1000 double cylinder.
6) The Kwikset 660 is a residential deadbolt - what is the equivalent for a commercial classroom door?
The Kwikset 660 is classified for residential use. On a commercial classroom opening, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, and the Falcon D211 is the Grade 2 medium duty classroom function version with single cylinder operation. Both are cylinder x thumbturn like the 660. The Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function for 1-3/4 inch doors, with a cylinder outside and a blank plate inside instead of a turn.
7) What is the closest equivalent to a Kwikset 660 single cylinder deadbolt from another brand?
The Kwikset 660 is a single cylinder deadbolt operated by key outside and thumbturn inside on a round rose, with an adjustable 2-3/8 inch to 2-3/4 inch backset latch. The Bravura 310RC Elite is the nearest match in form: a Grade 2 contemporary round deadbolt with cylinder x thumbturn function. If the round trim matters less than the certification, the Callan Model 200S-G2 is also a cylinder x thumbturn round trim deadbolt at Grade 2. Both keep the same key-outside, turn-inside operation on a round escutcheon.
8) The Kwikset 660 is ANSI/BHMA Grade 3 - what deadbolt should I use on a commercial opening that requires Grade 1?
The Kwikset 660 is ANSI/BHMA Grade 3 certified. For an opening specified at Grade 1, the Dexter DB1000 single cylinder deadbolt is a Grade 1 cylinder x thumbturn unit for 1-3/8 inch to 1-7/8 inch doors, the Deltana CL200LM is a Grade 1 single cylinder deadbolt, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors. All three keep the key-outside, turn-inside operation.
9) I need a deadbolt that is keyed on both sides instead of a thumbturn - what replaces the Kwikset 660?
The Kwikset 660 is single cylinder, so the inside is always a turn piece. For a glass-front or sidelight opening where the inside must also be keyed, the Callan Model 210S is a Grade 3 double cylinder deadbolt, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for the same thickness range. Check local egress code before specifying double cylinder on a required exit.
10) My doors are thicker than 1-3/4 inch - what deadbolt works where the Kwikset 660 does not?
For doors above the common 1-3/8 to 1-3/4 inch range, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 inch to 2-1/4 inch doors, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt covering 1-3/8 inch to 2 inch. The Dexter DB1000 single cylinder covers 1-3/8 inch to 1-7/8 inch and keeps the cylinder x thumbturn operation if the door is only slightly over.
11) The Kwikset 660 uses SmartKey - what should I use instead if my facility keys to Schlage C?
The Kwikset 660 SmartKey cylinder accepts Kwikset KW1 or Schlage SC1 keyway options. If your master key system runs Schlage C rather than SC1, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder. For an interchangeable core system, the Deltana CL200LAIC is a Grade 2 single deadbolt prepped for IC less cylinder, and the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core.
12) Which of these deadbolts look like substitutes for the Kwikset 660 but are not?
Several deadbolt-family parts do not replace a bored tubular deadbolt. The Arrow 460 is a mortise lock strike with a straight lip, not a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the BEST 8T is a tube component of the T Series - both are pieces of an assembly. The Emtek 2051 is a European mortise deadbolt with an integrated roller latch, which needs a mortise pocket rather than the bored prep a 660 uses. The Falcon H2101 is an entrance interconnected lock with a single cylinder deadbolt, so it replaces both the knob and the deadbolt in one bored pair.
13) What tools do I need to install a Kwikset 660 deadbolt on a door that already has a deadbolt?
A screwdriver. On a door with an existing deadbolt bore, the 660 is a straight swap: set the latch to your backset, drop it in the edge bore, put the outside cylinder and inside turn piece through the cross bore, and screw it together. No drilling and no special tools if the prep is already there. The round rose trim covers a standard round deadbolt prep.
14) Which deadbolt should I use for a rental turn where I have to rekey between tenants?
The 660 with SmartKey is built for exactly that. You rekey the cylinder in place in seconds with the existing key and the new one, so a unit turn does not mean pulling hardware or calling a locksmith, and you can keep the whole property on either KW1 or SC1. The latch is also treated with Microban antimicrobial protection. If you need an interchangeable core instead so a master key system can be serviced by a locksmith, look at the Deltana CL200LAIC single cylinder deadbolt with a 2-3/4 inch backset.
15) I need a fire rated deadbolt for a rated door assembly. Does the Kwikset 660 work?
The 660 is a Grade 3 residential deadbolt and no fire rating is carried on it, so it is not the part for a rated opening. Use a deadbolt that states one: the Hager 3115 (Grade 2 cylinder x thumbturn) and Hager 3215 (Grade 2, 1 inch throw) are both fire rated for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal CRB800 has a UL 3-hour fire rated latch.
16) What is a simpler alternative to the Kwikset 660 for a door that does not need a key outside?
The Kwikset 660 is keyed outside with a turn piece inside, for exterior doors where keyed entry is needed. Where the outside never needs a key - a stockroom or an exit-only leaf - the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside, for 1-3/8 inch to 1-3/4 inch doors. For a door with only one side bored, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt.
17) What deadbolt has an easier thumbturn to operate for accessibility?
The Kwikset 660 locks with a turn piece on the interior. Where an easier grip is needed, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, for 1-3/8 inch to 1-3/4 inch doors. It keeps the same cylinder x thumbturn function, so the keyed side of the opening behaves the same way.
18) Is there another Grade 3 deadbolt with an adjustable backset like the Kwikset 660?
The Kwikset 660 latch adjusts from 2-3/8 inch to 2-3/4 inch to fit standard door preparations. The Cal-Royal ED500 is also a Grade 3 single cylinder deadbolt with an adjustable backset, covering 1-3/8 inch to 1-3/4 inch doors on cylinder x thumbturn function. The Brinks Raleigh is a transitional round single cylinder deadbolt with a 4-way adjustable backset, which keeps the round trim as well.
19) What should I use instead of a Kwikset 660 if I want keypad or credential access rather than a key?
The Kwikset 660 is a mechanical deadbolt keyed outside. For credential-based access on the same door position, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt for a portfolio of units.
20) What is a heavier deadbolt than the Kwikset 660 for a high-traffic multi-family entry?
The Kwikset 660 is Grade 3. Where the traffic calls for a heavier build, the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder deadbolt for 1-3/4 inch doors, and the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard that keeps cylinder x thumbturn operation. The Arrow DBX61 is a Grade 2 single cylinder deadbolt, also cylinder x thumbturn.
21) I want a decorative deadbolt instead of the Kwikset 660 satin nickel or matte black - what are the options?
The Kwikset 660 comes in Satin Nickel, Satin Chrome, Bright Chrome, and Matte Black. For a decorative program, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt in cylinder x thumbturn function, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. The Baldwin Reserve Contemporary Round is a double cylinder round deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt. Note the Emtek 8323 and both Baldwin units are double cylinder, so the inside takes a key rather than a turn.
22) What finishes does the Kwikset 660 round deadbolt come in?
Four: satin nickel, satin chrome, bright chrome, and matte black. Satin nickel is the usual match for existing residential brushed hardware; matte black pairs with contemporary black levers and handlesets. Order the same finish across a building and the bolts will read as one set with the knobs and levers already hung.
23) Is there a square rose alternative to the Kwikset 660 round deadbolt?
The 660 RDT trim is round. For a square or rectangular escutcheon on the same kind of single cylinder, thumbturn-inside deadbolt, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Bravura Rectangle series is a Grade 2 single cylinder rectangle, and the Brinks Mendocino is a contemporary square single cylinder with a 4-way adjustable backset. All three keep the cylinder x thumbturn function, only the trim shape changes.
