Kwikset KWI-400T-26DS – Frequently Asked Questions

1) Do I have to order the Kwikset Tylo knob handed for a left or right hand door?
No handing to specify. The Tylo 400T is reversible and fits both left and right hand doors, so one part number covers every opening in the building. That matters if you are buying a quantity for a property and do not want to survey swing direction door by door.
2) Can I key the Kwikset 400T SMT to my existing Kwikset KW1 keys?
That is what SmartKey is for. The 400T SMT re-keys in seconds with the SmartKey tool and works with either the Kwikset KW1 or Schlage SC1 keyway, so you can bring a new lock onto a key you already carry rather than adding another key to the ring. Two keys come in the box. When ordering, pick Keyed Different or Keyed Alike, and if you want them cut to a specific bitting there is a key code field on the order.
3) What does the entry function on the Kwikset 400T actually do when someone locks it?
Entry/office function. The turn button on the inside knob locks both knobs; the outside knob is then released by key. Turning the inside button back, or keying the outside, unlocks it. It is a single cylinder lock, so there is no key on the inside face. That is the right function for a main entry or an office door, and the wrong one for a bath or bedroom, where a privacy set is what you want.
4) Is a Grade 3 Kwikset knobset enough for an apartment building or a commercial office door?
The 400T Tylo is ANSI/BHMA Grade 3 and catalogued as a residential lock, which is the right level for house and apartment interior and unit doors but light for a commercial door taking daily public traffic. For that, step up: the BEST 8K Series is a Grade 1 heavy duty entrance knob lock, and the Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical knob covering 1-3/8 to 2 inch doors. Grade 1 is the top ANSI/BHMA cycle and strength tier, Grade 3 the entry tier.
5) Will the Kwikset Tylo latch work with the strike plate already in my door frame?
The set ships with a 2-1/4 inch full lip round corner strike. If your frame has a square corner strike mortised in, you can leave the existing strike and just fit the latch, or chisel the corners for the round one. On the latch end you get three interchangeable faceplates, round corner, square corner, and a drive-in collar, so the latch matches either a round or square corner mortise in the door edge, or a bored hole with no mortise at all.
6) I need a knob that locks from outside only and cannot be unlocked by a button inside - is the Kwikset 400T SMT Tylo the right one?
No. The Kwikset 400T SMT Tylo is Entry/Office function, locked and unlocked by the key outside or the turn button inside, which means anyone on the inside can leave it unlocked. For an opening that must stay locked outside at all times and only key operates, use a storeroom function knob: the Sargent 6G04 is a Grade 2 storeroom knob lock with a single cylinder, and the Sargent 8XG04 is the Grade 1 heavy duty storeroom version with a 2-3/4 inch backset. For a classroom door keyed outside with free egress, the Dexter C2000 classroom ball knob is a Grade 2 option for 1-3/8 inch to 1-3/4 inch doors.
7) What is the closest keyed entry knob to the Kwikset 400T SMT Tylo if I want the same Grade 3 entrance function from another brand?
The Cal-Royal BER00 is the nearest match. It is a Grade 3 knob lock in Entrance/Office function with a Kwikset keyway, and it fits doors 1-3/8 inch to 1-3/4 inch, the same door thickness range the 400T SMT Tylo covers. The 400T SMT Tylo is Grade 3, single cylinder, Entry/Office function. The difference to weigh is the cylinder: the 400T SMT carries SmartKey Security, which is rekeyed at the door, while the BER00 is a conventional Kwikset keyway cylinder rekeyed by a locksmith.
8) Is a dummy knob such as the Schlage A170 a substitute for the Kwikset 400T SMT Tylo?
No. The Schlage A170 is single dummy trim, a non-keyed knob with no latch and no bolt - it is fastened to the door as a pull. The Kwikset 400T SMT Tylo is a keyed single cylinder entry knobset with a latch, a 2-1/4 inch full lip round corner strike, and a turn button inside. Dummy trim like the A170, the BEST 6K single dummy, or the Emtek Hammered Egg dummy pair belongs on an inactive leaf or a closet door that is held by a ball catch, not on an opening that has to lock.
9) What entry knob should I use instead of the Kwikset 400T SMT Tylo on a door thicker than 1-3/4 inch?
The Kwikset 400T SMT Tylo fits doors 1-3/8 inch to 1-3/4 inch. For a thicker slab, the Deltana 3381 Egg Knob entry and the Deltana 6171 Round Knob entry both cover 1-3/8 inch to 2 inch, and the Corbin Russwin CK4851 Grade 1 Entrance/Office cylindrical lock also runs to 2 inch. If the door is thicker still, the Falcon X101 covers 1-3/8 inch to 2-1/4 inch, though it is a passage knobset rather than a keyed entry lock.
10) I need the Kwikset Tylo knob on a fire rated door, is that available?
There is an optional UL 1/3 hour fire rating available across the Tylo functions. If the opening is fire rated, that option has to be specified for the assembly to be compliant, so confirm the rating is on the units you are buying rather than assuming a standard set carries it.
11) Can I get matching passage and privacy knobs to go with the Kwikset 400T Tylo entry lock?
The Tylo line runs the full set of functions in the same knob: 200T passage for halls and closets, 300T privacy for bed and bath, 400T keyed entry, 401T passage with a free interior knob, and the 488T half dummy for a non turning single side. Buying within Tylo is how you keep one knob shape across a whole unit or floor when only some of those doors need a key.
12) What is the difference between the Kwikset 400T SMT and a Cal-Royal BER00 entrance knob lock?
Both are Grade 3 entrance/office knob locks for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal BER00 is built on the Kwikset keyway, so it keys into the same system. The split is the cylinder: the 400T SMT carries SmartKey, which lets you re-key it yourself in seconds without pulling the lock, while the BER00 is a conventional cylinder you re-key at a pinning bench. For a property manager doing turnovers, that difference is the whole decision.
13) I do not need a key on this door - what is the non-keyed version of a knob like the Kwikset 400T SMT Tylo?
It depends what the door has to do. For a hall or closet door that only needs to latch, the Pamex FTF Baron is a Grade 3 passage knob lockset for doors 1-3/8 inch to 1-3/4 inch. For a bath or bedroom that needs a push-button but no key, the Pamex FTF Baron privacy and the Cal-Royal BER20 are both Grade 3 privacy knobs in that same 1-3/8 inch to 1-3/4 inch range. The Kwikset 400T SMT Tylo is a keyed single cylinder entry knob, so a passage or privacy knob is the right swap when the opening does not need a key outside.
14) Which knob locks compete with the Kwikset 400T SMT Tylo for a residential keyed entry door?
Several Grade 3 keyed entry knobs sit in the same slot as the Kwikset 400T SMT Tylo. The Master Lock BC Series biscuit knob is a Grade 3 keyed entry knob. Callan offers the Canova and the Santo as Grade 3 entrance knobsets, and Delaney the Belton, Galway and Olivia in the same grade and function. The Pamex FTF Baron is a Grade 3 Entrance/Office knob for 1-3/8 inch to 1-3/4 inch doors. What separates the 400T SMT Tylo from all of them is SmartKey Security, which lets the lock be rekeyed at the door, plus Microban on the finish.
15) Can I use the Kwikset 400T SMT Tylo where a fire-rated knob lock is called for?
The Kwikset 400T SMT Tylo carries an optional UL 1/3 hour fire rating across its functions, so the rating has to be specified rather than assumed. If the opening needs a knob lock that is fire rated as standard, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock with a fire rating and a 2-3/4 inch backset, and the Falcon X101 is the Grade 1 heavy duty fire rated version with an interchangeable core. Both W101 and X101 are passage function, so they suit an opening that needs the rating but not a key.
16) If I am doing a whole house and need matching knobs on the keyed and non-keyed doors, is there an alternative to buying the Kwikset 400T SMT Tylo separately?
The Schlage Residential F500 Plymouth with Georgian knob is sold as a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch, which puts the matching keyed and non-keyed trim in one box. The Sure-Loc Bergen round knob comes as a 6-pack with adjustable backset for a run of interior doors. The Kwikset 400T SMT Tylo covers only the keyed entry opening, with an adjustable 2-3/8 or 2-3/4 inch backset, and it is matched by other Tylo functions in the same collection.
17) Is the Lockey 3830 keyless knob an alternative to the Kwikset 400T SMT Tylo if I want to stop handing out keys?
They solve the problem differently. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch, so access is by code and there is no cylinder to key at all. The Kwikset 400T SMT Tylo keeps a key but uses SmartKey Security, which is rekeyed at the door in seconds, so a turned-over tenant or crew is handled by rekeying rather than by changing a code. For a door where you want no keys in circulation, the 3830 is the swap; where you want to keep keys but control who has a working one, the 400T SMT is the fit.
18) Is the Sargent 28C-KNOB a replacement for the Kwikset 400T SMT Tylo?
No. The Sargent 28C-KNOB is exit device trim - a knob and rose that mounts to a Sargent 28 Series exit device on a 1-3/4 inch door, not a lock in its own right. The same goes for the Sargent 78-2875, which is an outside knob only in B design, and the Imperial USA ED-BKL580, which is knob trim in storeroom function for the ED-500 exit device series. The Kwikset 400T SMT Tylo is a complete cylindrical knobset with its own latch and strike, so it goes into a bored door, not onto a panic device.
19) What finishes does the Kwikset 400T Tylo keyed knob come in so I can match the rest of my doors?
Five finishes on the Tylo entry knob: 619 satin nickel, 626 satin chrome, 625 polished chrome, 605 polished brass, and 609 antique brass. Satin nickel and polished brass are the two that most commonly match existing residential trim. The Tylo knob shape is traditional, so it sits alongside older brass hardware without looking out of place.
20) Is there an antimicrobial knob option for a healthcare or hospitality property?
The Tylo 400T carries Microban treatment along with SmartKey. That is a surface treatment on the lock, useful on high touch doors in hospitality and residential care settings, though it is not a substitute for any facility grade requirement your spec calls out.
21) Can I install the Kwikset 400T Tylo myself or does it need a locksmith?
A screwdriver does it. The 400T is a bored cylindrical lock, so it goes into the existing 2-1/8 inch cross bore and 1 inch edge bore that any standard prepped door already has, and the adjustable latch handles either backset without a swap. Install runs a few minutes per door.
22) I want a traditional look with more decorative trim than the Kwikset 400T SMT Tylo - what keyed knobs should I look at?
The Kwikset 400T SMT Tylo is a traditional style knob offered in polished brass, antique brass, satin nickel, polished chrome and satin chrome. For heavier decorative trim on a keyed opening, Deltana offers the 3381 Egg Knob entry and the 6171 Round Knob entry, both for doors 1-3/8 inch to 2 inch, and the 6901 Portland Knob entry for 1-3/8 inch to 1-3/4 inch. On the non-keyed doors alongside them, the Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Omnia 434/PA egg-shaped knob latchset carry the same decorative treatment.
23) Does the handing of the door affect whether I choose the Kwikset 400T SMT Tylo or a competing entry knob?
Not for the Kwikset 400T SMT Tylo itself - it is reversible and fits both right handed and left handed doors, so one part number covers either swing. Among the alternatives, the Dexter C2000 entry/office ball knob is a Grade 2 keyed knob for 1-3/8 inch to 1-3/4 inch doors and the Cal-Royal BER00 is a Grade 3 Entrance/Office knob over the same range, both cylindrical knobsets where the knob itself is symmetrical. Handing on any of these comes down to the latch and strike orientation at the jamb rather than to ordering a left or right part.
