Kwikset 660RDT-15-SMT-RCAL-RCS – Frequently Asked Questions

1) Will the Kwikset 660 SmartKey deadbolt fit my existing door prep, or do I need to know the backset first?
The 660 ships with an adjustable latch that covers both standard residential backsets, 2-3/8 inch and 2-3/4 inch, so you do not need to measure before ordering. Set the latch to match the cross bore center on your door and it drops into a standard deadbolt prep. Faceplate corners are round, so if your existing latch mortise was cut with a router (round corners) it goes straight in; a square-corner mortise would need the corners chased.
2) Can I key this Kwikset SmartKey deadbolt to match the Schlage keys my tenants already carry?
Yes, within limits. SmartKey re-key technology on the 660 accepts either the Kwikset KW1 keyway or the Schlage SC1 keyway, so you can re-key it on the door to an existing SC1 key in seconds with the SmartKey tool and a working key. The listed keyway profile is KW1 and two keys come in the box. It will not take any other keyway family, so a restricted or proprietary key system is out.
3) Is the Kwikset 660 deadbolt rated for a commercial building or apartment corridor?
It is a residential-duty lock, ANSI/BHMA Grade 3. That is fine for apartment unit entry doors and single-family exteriors, but if a spec or code official is calling for Grade 1 or Grade 2, look at the Cal-Royal CB160 (Grade 2 single cylinder with a tamper-resistant cylinder guard) or the Cal-Royal CRB800 Grade 1 heavy duty single cylinder deadbolt. The Accentra D111 is another Grade 1 cylinder x thumbturn option.
4) Does the Kwikset 660 have a key on both sides, or a thumbturn inside?
Key outside, thumbturn inside. That is single cylinder function. On a door with glass within reach of the lock, some jurisdictions push you to a double cylinder instead, which takes a key on both sides. For that, the Dexter DB1000 double cylinder (Grade 1) or DB2000 double cylinder (Grade 2) are options, as is the Callan Model 210S. Be aware double cylinder locks are restricted on required egress doors in many areas.
5) Will the Kwikset 660 latch reach my existing strike, or do I have to re-cut the jamb?
The bolt throws a full 1 inch, which is what a standard deadbolt strike pocket is bored for, so in most replacements it reaches the existing hole. The round corner strike included in the box is a full lip round strike, so it covers a router-cut jamb mortise cleanly. If your jamb was cut square, either chisel the corners or reuse the old square strike plate.
6) What is a comparable single cylinder deadbolt with an adjustable backset if the Kwikset 660 contemporary SmartKey deadbolt is not the right fit?
The Cal-Royal ED500 is the closest like-for-like alternative. It is a Grade 3 single cylinder deadbolt with an adjustable backset and a cylinder x thumbturn function, matching the Kwikset 660's Grade 3 certification, adjustable 2-3/8 inch to 2-3/4 inch latch, and key outside / thumbturn inside operation. The ED500 fits doors 1-3/8 inch to 1-3/4 inch thick. The main difference is keying: the Kwikset 660 uses SmartKey re-key technology on a KW1 keyway, which the ED500 does not offer.
7) I need a heavier duty deadbolt than a Grade 3 residential unit for a commercial entry - what should I use instead?
Step up to a Grade 1 single cylinder deadbolt. The Accentra D111 is Grade 1, cylinder x thumbturn, and fits doors 1-3/8 inch to 1-3/4 inch thick. The Dexter DB1000 single cylinder is also Grade 1 cylinder x thumbturn with a 1-3/8 inch to 1-7/8 inch door thickness range. The Kwikset 660 is ANSI/BHMA Grade 3 and is classified as residential, so on a high-traffic commercial opening one of those Grade 1 units is the better match.
8) I need a deadbolt keyed on both sides for a door with glass nearby - what takes the place of a single cylinder unit?
Use a double cylinder deadbolt, which is keyed on the interior instead of using a thumbturn. The Dexter DB2000 double cylinder is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, and the Dexter DB1000 double cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch. The Callan Model 210S is a Grade 3 double cylinder. The Kwikset 660 is a single cylinder deadbolt operated by key outside and thumbturn inside, so it will not serve that opening. Confirm your local egress code before specifying a double cylinder.
9) Does the Kwikset 660 SmartKey deadbolt work on a fire rated opening, or do I need something else?
For a fire rated opening, look at deadbolts that carry a fire rating in their specs. The Hager 3215 is a single cylinder Grade 2 deadbolt with a 1 inch throw carrying a fire rating and fitting doors 1-3/8 inch to 1-3/4 inch thick, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Kwikset 660 is a Grade 3 residential deadbolt with a 1 inch throw and SmartKey re-keying.
10) I have a Schlage SC1 keyed building - does the Kwikset 660 fit, or should I look at a Schlage C keyway deadbolt?
The Kwikset 660 is supplied on the KW1 keyway, and its SmartKey re-key technology is compatible with Kwikset KW1 or SC1 keyway options. If you would rather buy a deadbolt factory-cut to the Schlage C keyway, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway for doors 1-3/8 inch to 1-3/4 inch, and the Hager 3214 is the double cylinder version on the same keyway.
11) I want to standardize a facility on small format interchangeable core - what deadbolt replaces the SmartKey version?
SmartKey is a proprietary re-keying system on the Kwikset 660 and is not an interchangeable core. For SFIC standardization, the Arrow E61 is a Grade 2 single cylinder deadlock prepped for SFIC less core for doors 1-3/8 inch to 1-3/4 inch, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt for interchangeable core supplied less cylinder, and the Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
12) I manage 40 units and re-key on every turnover. Is SmartKey actually worth it over a standard deadbolt?
That is exactly the use case it pays for. SmartKey lets you re-key the lock at the door in seconds with the existing working key and the SmartKey tool, no cylinder pull, no pinning kit, no locksmith call. Across a turnover-heavy portfolio that removes the re-key line item entirely. The trade-off is that it is a Grade 3 residential lock, so for a heavier opening you would be pinning cylinders on something like the Cal-Royal CB160 Grade 2 instead.
13) What is a mid-grade alternative between the Kwikset 660 SmartKey deadbolt and a full Grade 1 commercial deadbolt?
Grade 2 single cylinder deadbolts sit in between. The Dexter DB2000 single cylinder is Grade 2, cylinder x thumbturn, for doors 1-3/8 inch to 1-3/4 inch. The Arrow DBX61 and the Cal-Royal CB160 are also Grade 2 single cylinder deadbolts, with the CB160 adding a tamper-resistant cylinder guard. The Kwikset 660 is Grade 3 with SmartKey re-keying, which none of those three carry.
14) Is there a contemporary-styled deadbolt in a square trim instead of the round contemporary Kwikset 660?
Yes. The Bravura 310SC Elite is a Grade 2 contemporary square deadbolt with cylinder x thumbturn function, and the Brinks Mendocino Series E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. If you want to stay round, the Bravura 310RC Elite is a Grade 2 contemporary round deadbolt. The Kwikset 660 is a contemporary single cylinder deadbolt with SmartKey re-keying.
15) Which products look like a substitute for the Kwikset 660 deadbolt but will not actually work as one?
A few in the same family are not drop-in equivalents. The Arrow 460 is a mortise lock strike, not a lock body. The BEST 8T is a tubular deadbolt tube component rather than a complete deadbolt. The Baldwin Reserve 8BR0618001 is a deadbolt spacer. The Arrow E60 is a non-keyed exit deadlock with a blank plate outside and thumbturn inside, so it gives no keyed entry. The Kwikset 660 is a complete single cylinder deadbolt with key outside and thumbturn inside, shipped with an adjustable latch and a round corner strike.
16) What should I use on a classroom or school door instead of a residential SmartKey deadbolt?
Classroom function deadbolts are the right call there. The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset and cylinder x thumbturn operation, and the Falcon D211 is the Grade 2 medium duty classroom version with single cylinder operation. The Hager 3118 is a Grade 1 classroom deadbolt on the Schlage C keyway with a 6-pin cylinder for doors 1-3/8 inch to 1-3/4 inch. The Kwikset 660 is a Grade 3 residential deadbolt.
17) My door is thicker than 1-3/4 inch - which deadbolt should I specify?
Look at units that publish a wider door thickness range. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock for doors 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt for doors 1-3/8 inch to 2 inch. The Dexter DB1000 single cylinder Grade 1 covers 1-3/8 inch to 1-7/8 inch if you are only slightly over.
18) If I want keyless or electronic access instead of a keyed SmartKey deadbolt, what are the options?
Several electronic deadbolts cover that. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, and the CL2210 is an electronic mortise deadbolt. For multihousing RFID credentials, the Dormakaba Nova-D is a smart electronic deadbolt and the Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Kwikset 660 is mechanical, operated by key outside and thumbturn inside.
19) Is there a deadbolt with an easier-to-grip thumbturn for accessibility?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, cylinder x thumbturn function, for doors 1-3/8 inch to 1-3/4 inch thick. It matches the Kwikset 660's Grade 3 rating and key-outside, thumbturn-inside operation while adding the ergonomic turn piece.
20) What deadbolt should I use on a door with only one side bored or no interior trim?
For a half-bore opening, the Callan Model 205S is a Grade 3 one-sided deadbolt. If you need a cylinder-by-blank arrangement on a commercial door, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock with cylinder x blank for 1-3/4 inch doors. The Kwikset 660 is a full single cylinder deadbolt requiring both sides prepped, with a key cylinder outside and a thumbturn inside.
21) I need both a latch and a deadbolt on the same entry door - what replaces a standalone deadbolt?
An interconnected lock combines the two. The Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, so one device handles latching and deadbolting. The Kwikset 660 is a deadbolt only, keyed outside with a thumbturn inside, and would be paired with a separate knob or lever set.
22) What finish does the Kwikset 660 SmartKey deadbolt come in?
Satin nickel, with contemporary round trim. If the rest of the building is on square escutcheons, the Bravura 310SC Elite or the Brinks Mendocino Series are contemporary square deadbolts; the Bravura 310RC Elite is the round contemporary equivalent.
23) What tools do I need to install the Kwikset 660 deadbolt?
A screwdriver, assuming the door is already bored for a deadbolt. The 660 is a tubular deadbolt: latch into the edge bore, cylinder and thumbturn through the cross bore, two screws through the back. No mortising and no drilling if you are replacing an existing deadbolt on a standard prep. New bore work would need a 2-1/8 inch hole saw and a 1 inch spade bit for the edge.
24) Is there anything on this Kwikset deadbolt for a healthcare or high-touch facility?
The latch carries Microban antimicrobial product protection, which Kwikset states keeps the hardware 99.9 percent cleaner than unprotected surfaces. Useful in assisted living, clinics, or shared-entry multifamily where touch surfaces get wiped constantly. Note it is still a Grade 3 residential lock, so it suits unit doors rather than heavy traffic corridor openings.
