Kwikset 405CSL-SQT-15-SMT-6AL-RCS-KA – Frequently Asked Questions

1) Do I need to order a handed version of the Casey lever for a left hand door?
No handing to specify. The Casey 405CSL lever is fully reversible and installs on right or left hand doors, so one part number covers every opening in the building. That also means a property manager stocking spares only needs one SKU per finish.
2) Can I key the Kwikset Casey entry levers alike so one key runs all the units?
Yes. The Casey 405CSL uses SmartKey Security, which lets you re-key each lock yourself in seconds with no cylinder removal, and it is offered keyed alike so a set of doors runs on one key. SmartKey works with the Kwikset KW1 keyway or the SC1 keyway, so you can bring existing site keys into the system rather than issuing new ones. Two keys come with the lock.
3) What is the Kwikset 405CSL Casey lock function, and does the inside lock without a key?
Entry/office, single cylinder. The outside lever is locked and unlocked by key; the inside has a turn button, so anyone leaving turns the piece on the inside and no key is needed from the secure side. That is the standard function for a main entry, unit door, or an office someone wants to secure behind them.
4) Is the Kwikset Casey 405CSL rated for a commercial corridor or an apartment building entry?
It is ANSI/BHMA Grade 3 and catalogued as residential duty, which suits single family, condo units and light traffic doors. For a commercial corridor, a stairwell, or a high traffic multi-family entry, step up to a Grade 1 or Grade 2 cylindrical entry lever: the Hager 2525 is a Grade 2 commercial cylindrical entry lock fitting 1-3/8 to 2 inch doors, and the Dexter C1000 entry/office is Grade 1 with a clutching lever for 1-3/8 to 1-3/4 inch doors. Grade 3 is the light duty tier of the ANSI/BHMA scale, so on a door cycled all day it will wear out first.
5) Is the Kwikset Casey 405CSL lever available fire rated?
Fire rated and non fire rated versions are both offered, in all three finishes: Satin Nickel, Polished Chrome and Matte Black. If the opening is a rated door assembly, select the fire rated option at order time rather than assuming the standard one carries it.
6) What is the closest equivalent to the Kwikset 405CSL Casey keyed entry lever from another brand?
The Master Lock BC Series RL01 return style lever is the nearest match in function and grade: it is a Grade 3 keyed entry lever, the same grade and entrance function the 405CSL Casey carries. The Casey differs in that it uses SmartKey Security, which lets the lever be re-keyed at the door, and it ships with a round corner strike. Both are lever-handle keyed entry sets for residential openings.
7) Is there a Grade 3 entry lever alternative to the Kwikset Casey that uses a standard pin cylinder instead of SmartKey?
Yes. The Cal-Royal AUS00 is a Grade 3 entrance/office lever lock with a solid brass forged body, fitting doors 1-3/8 inch to 1-3/4 inch, and the Callan Artino CLN-360201 is a Grade 3 entrance leverset. Both carry the same Grade 3 rating as the Kwikset 405CSL Casey, which uses SmartKey Security for owner re-keying. If a locksmith is keying the building on an existing pin system, the Cal-Royal or Callan sets avoid the SmartKey cylinder entirely.
8) Can a Cal-Royal AG05 storeroom lever replace a Kwikset 405CSL Casey entry lever?
No, the functions are different. The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, which means the outside lever stays locked at all times and a key is required every time. The Kwikset 405CSL Casey is an entry/office function: the outside lever is locked or unlocked by key outside or by the turn button inside, so it can be left in a passage state during business hours. Use the AG05 where the door must never be left unlocked, and the Casey where staff need to unlock it and leave it.
9) My doors are 2 inches thick. Will a Kwikset 405CSL Casey lever fit, or do I need something else?
The Kwikset 405CSL Casey covers doors 1-3/8 inch to 1-3/4 inch thick. For a 2 inch door, the Hager 2525 Grade 2 commercial entry lever covers 1-3/8 inch to 2 inch, and the Deltana 6201 Manchester entry lever covers 1-3/8 inch to 2 inch. The Falcon K101 Grade 1 goes further at 1-3/8 inch to 2-1/4 inch, though it is a passage function rather than keyed entry.
10) What entry lever works with a Schlage C keyway instead of the Kwikset SmartKey cylinder?
The Cal-Royal AG00 entrance lever is a Grade 2 set with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, fitting doors 1-3/8 inch to 1-3/4 inch. The Kwikset 405CSL Casey uses SmartKey Security and is compatible with the Kwikset KW1 or SC1 keyway options, with a backset adjustable to 2-3/8 or 2-3/4 inch. If the building is already pinned on a Schlage C system and the keys come from an existing bitting list, the AG00 drops onto that system directly.
11) What is the difference between the Kwikset 405CSL Casey and the Falcon B511CP6D for an office door?
Both are entry/office function lever locks. The Falcon B511CP6D is Grade 2 and medium duty, built for commercial traffic. The Kwikset 405CSL Casey is Grade 3, residential, with SmartKey Security for re-keying at the door and a backset adjustable to 2-3/8 or 2-3/4 inch. For a tenant office inside a commercial building with steady daily cycles, the Falcon is the commercial-duty option; for a unit door in multi-family housing where the lock is re-keyed at turnover, the SmartKey cylinder on the Casey is what shortens that job.
12) What finishes does the Kwikset 405CSL-SQT Casey keyed entry lever come in?
Three: Satin Nickel (15S), Polished Chrome (26S) and Matte Black (514S). If you are matching other openings, the same three finishes run across the Casey collection, so the 200CSL passage, 300CSL privacy and 488CSL half dummy in the square rose can be finished to match this keyed entry on the rest of the doors.
13) Does the Kwikset Casey 405CSL come with a strike, or do I need to order one?
A round corner strike ships with it. That matches the radius corner prep in most pre-hung metal and wood jambs, so nothing extra is needed for a like-for-like replacement. If your frame is cut for a square corner strike or a full lip strike, the included plate will not drop in and you will need to swap the strike.
14) What is the difference between the Casey SQT and RDT lever, and can I mix them on a job?
SQT is the square rose, RDT is the round rose. Mechanically they are the same Casey keyed entry lever with SmartKey, so both take the same 1-3/8 to 1-3/4 inch doors and the same 2-3/8 or 2-3/4 backset. The choice is purely the trim shape at the door face, so pick one and carry it across passage, privacy and dummy functions in the Casey collection to keep the building consistent.
15) I only need the door to latch, not lock. What do I order instead of the 405CSL Casey keyed entry?
Stay inside the Casey collection and drop the cylinder. For a hall or closet that just needs to latch, the 200CSL passage lever is the match; for a bed or bath, the 300CSL privacy lever gives you the inside push button without a key; for a false or inactive leaf, the 488CSL half dummy is a non-turning one-sided lever. All are offered in the same square rose (SQT) as the 405CSL so the trim matches across the unit.
16) What else is a Grade 3 keyed entry lever if I want an alternative to the Kwikset Casey?
Two peers sit at the same grade. The Master Lock BC Series RL01 is a Grade 3 return style lever keyed entry lockset, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body that fits 1-3/8 to 1-3/4 inch doors, the same range as the Casey. The Callan Artino is a Grade 3 entrance leverset as well. What the Casey brings that those do not is SmartKey, so if self re-keying or keying alike to an existing KW1 or SC1 site key matters, that is the deciding difference.
17) What tools do I need to install a Kwikset 405CSL Casey lever, and can my maintenance tech do it?
A screwdriver. The Casey 405CSL is a bored cylindrical lockset that installs in minutes with no special tooling, and the latch adjusts between 2-3/8 and 2-3/4 inch backset so you are not measuring and reordering when the prep turns out different from what you expected. Combined with the reversible lever, a single tech can carry one box to any door in the building.
18) I need a keyed entry lever for a classroom door instead of a Kwikset Casey. What are the options?
Classroom function is a different lock entirely. The Dexter C1000 Series classroom lever is Grade 1 with a clutching mechanism for doors 1-3/8 inch to 1-3/4 inch, the Dexter C1000 classroom security lever adds key control of the inside lever, and the Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset. The Kwikset 405CSL Casey is an entry/office function lever, which does not provide classroom lockdown.
19) What Casey-style lever should I order for interior doors that do not need a key?
The Kwikset Casey collection includes the 200CSL passage and 300CSL privacy levers in the same square rose trim as the 405CSL keyed entry, so the trim matches down a hallway. If the trim does not need to match Kwikset, the Callan Asheville CLN-AH5011 is a Grade 3 passage leverset in satin nickel, and the Bravura Tampa BVR-BV333702 is a Grade 2 passage leverset with square trim. The 405CSL itself is keyed, single cylinder, with a turn button inside.
20) What is an alternative to the Kwikset Casey SmartKey lever if I do not want to issue keys at all?
Keyless lever sets cover that opening. The Delaney LP250 is a Grade 2 electronic keypad leverlock, the Lockey 1150S is a mechanical keypad heavy duty lever set with an adjustable backset for doors 1-1/8 inch to 2 inch, and the Lockey 2835 is a mechanical pushbutton keyless lever with passage function and ADA compliance for doors 1-3/16 inch to 2 inch. The Kwikset 405CSL Casey is a keyed single cylinder lever and comes with 2 keys.
21) Is an Imperial USA ED-EL500HD lever trim a substitute for a Kwikset 405CSL Casey lever?
No. The Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim with entry function, meaning it is the outside trim that mounts to an exit device rather than a standalone lock. The Kwikset 405CSL Casey is a complete cylindrical lever lock with its own adjustable latch and round corner strike. Order the ED-EL500HD only when there is already an exit device on the door.
22) Does the Kwikset Casey lever have an antimicrobial coating for a healthcare or hospitality door?
Yes, the Casey 405CSL carries Microban antimicrobial product protection, which Kwikset states keeps the hardware 99.9 percent cleaner than unprotected surfaces. Worth noting it is built into the finish, so it does not wear off with cleaning the way a topical treatment would, and it is a differentiator on high touch doors. Bear in mind the lock is Grade 3 residential duty, so it suits guest rooms and units more than a hospital corridor.
23) What matching dummy lever goes with a keyed entry lever run like the Kwikset Casey?
Kwikset offers the 488CSL SQT Casey half dummy in the same square rose trim as the 405CSL keyed entry, so a closet or inactive leaf matches the keyed doors. Across brands, the Callan Bentley CLN-BN5051 is a Grade 2 dummy lever, the BEST 7KC Series single dummy trim is a Grade 2 medium duty lever, and the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim. Dummy levers do not latch and mount as trim only.
