Kwikset 400T-26DS – Frequently Asked Questions

1) My door is bored for a 2-3/4 inch backset. Does the Kwikset 400T Tylo need a different latch?
No separate part needed. The 6AL latch that comes with the Tylo 400T adjusts between 2-3/8 and 2-3/4 inches, so it drops into either of the two backsets found on residential doors. Set the latch to match the hole you already have before you slide it in.
2) What is the difference between the SmartKey and non-SmartKey versions of the Kwikset 400T Tylo?
SmartKey is Kwikset's rekeying cylinder: you can rekey the lock yourself with the existing key and a learn tool instead of pulling the cylinder or calling a locksmith. The Tylo 400T is sold both ways, SmartKey and standard cylinder, and the choice is an order-form decision you make per lock. If you manage a portfolio and turn units between tenants, the SmartKey version is the one that saves the trip; for a single door that never changes hands, the standard cylinder does the same job.
3) I'm replacing an old Kwikset entry knob on a house. Will the Tylo 400T go into the same holes?
If the existing opening is a standard 1-3/8 to 1-3/4 inch door bored for a 2-3/8 or 2-3/4 inch backset, the Tylo 400T lands in it, because the 6AL latch adjusts to both backsets and the set is built for those thicknesses. What can catch you is the strike: the Tylo ships with a round corner square plate, so a square-cornered jamb mortise needs touching up. It is a screwdriver job otherwise.
4) What is a commercial equivalent to the Kwikset 400T Tylo entry knob for a leased unit that needs a graded lock?
The Kwikset 400T Tylo is a residential keyed entry knob. For an opening that needs a graded commercial lock in the same entrance function, the Callan Edgewood is a Grade 2 entrance knobset and the BEST 8K Series is a Grade 1 heavy duty entrance knob lock. The Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical knob with a conventional cylinder that accepts doors 1-3/8 inch to 2 inch thick, wider than the 1-3/8 inch to 1-3/4 inch range the 400T covers.
5) Which keyed entry knob uses the Kwikset keyway so it can be keyed into an existing Kwikset system?
The Cal-Royal BER00 is a Grade 3 entrance/office knob lock built with a Kwikset keyway, fitting doors 1-3/8 inch to 1-3/4 inch. That makes it the direct alternative when a building is already keyed to Kwikset and the Kwikset 400T Tylo is not the knob style wanted. Note that the 400T is also offered with SmartKey, which is rekeyed by the user rather than by pinning.
6) What keyed knob should be used on a door thicker than 1-3/4 inches?
The Kwikset 400T Tylo covers standard doors from 1-3/8 inch to 1-3/4 inch. For a thicker leaf, the Deltana 3381 Egg Knob entry and the Deltana 6171 Round Knob entry both accept 1-3/8 inch to 2 inch doors, and the Corbin Russwin CK4851 Grade 1 entrance/office knob also spans 1-3/8 inch to 2 inch. The Falcon X101 goes to 2-1/4 inch, though it is a passage function with no key.
7) Which knob lock should be used on a fire-rated opening instead of a residential entry knob?
The Kwikset 400T Tylo is a residential keyed entry knob. Where the opening carries a fire label, 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 a Grade 1 heavy duty fire rated knobset with an interchangeable core. Both are passage/closet function, so a separate keyed device is needed if the opening must also lock.
8) Which knob lock should be specified when a room must stay locked from the outside at all times?
The Kwikset 400T Tylo is entrance function, so the outside knob can be left unlocked. For a storage or utility room that must always be locked outside with free egress inside, the Sargent 6G04 is a Grade 2 standard duty storeroom knob lock with a single cylinder, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom knob lock with a 2-3/4 inch backset.
9) Does the Kwikset 400T Tylo come with a strike plate, or do I have to buy one?
An RCS strike is in the box. RCS means round corner square, the strike shape that matches a frame mortised with a radius-corner router rather than a square chisel cut. If your jamb already has a square-cut strike pocket, that plate will not sit flush without dressing the mortise.
10) Does handing matter when I order the Kwikset Tylo 400T entry knob?
No. The Tylo keyed entry knobset is reversible, so one part number covers a left-hand or right-hand door. You set the latch orientation during install rather than specifying it on the order.
11) What else could I buy instead of the Kwikset 400T Tylo keyed entry knob?
Same residential entry job, other brands: the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 to 1-3/4 inch doors, close to a like-for-like swap. The Master Lock BC Series biscuit knob is a Grade 3 keyed entry, and Callan's Edgewood is a Grade 2 entrance knobset if you want a step up in grade while staying residential in look. One useful note if you are standardizing on Kwikset keys across a property: the Cal-Royal BER00 entrance/office knob is supplied with a Kwikset keyway, so it can be worked into the same key system.
12) Can I key the Kwikset Tylo 400T to match the other locks on the property?
Keying alike is the usual reason to pick the SmartKey version of the Tylo: it rekeys in place with the existing key, so a set of doors can be brought onto one key without pulling cylinders. If you are mixing brands and want a Kwikset key to run the whole property, the Cal-Royal BER00 entrance knob is furnished with a Kwikset keyway and works into the same system.
13) Is a dummy knob a substitute for a Kwikset 400T Tylo entry knob?
No. Dummy trim is a fixed knob with no latch and no cylinder, so it will not secure or even hold an exterior door closed the way the keyed 400T Tylo does. The Schlage A170 single dummy trim, the BEST 6K Series single dummy, and the Bravura Biloxi dummy knobset are all non-keyed dummy function and are used on inactive or closet door leaves only. Order dummy trim only when the door is held by a separate catch.
14) What should be used instead of a keyed entry knob on an interior door that does not need to lock?
The Kwikset 400T Tylo is keyed entry, meaning a key outside and a turn inside. For a hall or closet door that only needs a latch, the Pamex FTF Baron is a Grade 3 passage knob lockset for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C2000 passage ball knob is a Grade 2 non-keyed passage lock over the same door thickness range. For a bed or bath door, the Pamex FTF Baron privacy and the Dexter C2000 privacy knob cover the same openings with a push or turn button instead of a key.
15) What is a lower cost residential-grade alternative to the Kwikset 400T Tylo keyed knob?
For the same keyed entrance function in a Grade 3 residential build, the Master Lock BC Series biscuit knob is a Grade 3 keyed entry knob, and the Delaney Belton, Galway, and Olivia are Grade 3 entrance knobsets. The Callan Canova and Santo are also Grade 3 entrance knobsets. All are keyed entry like the 400T Tylo but come from a different keyway family, so they will not key into a Kwikset system without a keyway match.
16) What is the difference between the Kwikset 400T Tylo and the Schlage F500 Plymouth combo pack?
Both are residential knob hardware with adjustable backsets. The 400T Tylo is a single keyed entry knob supplied with the 6AL adjustable latch, which sets to 2-3/8 inch or 2-3/4 inch, and an RCS strike. The Schlage Residential F500 Plymouth with Georgian knob is a combo function set with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch, pairing more than one device rather than a single lock.
17) Is there a keyless alternative to a keyed entry knob for a shared back door?
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. It replaces the key the Kwikset 400T Tylo requires with a pushbutton code, which suits an opening used by rotating crews where issuing keys is the problem.
18) Is exit device knob trim the same as a keyed entry knobset?
No. The Sargent 28C-KNOB is exit device trim with a knob and rose in entrance function for 1-3/4 inch doors, and the Imperial USA ED-BKL580 is storeroom function knob trim in the ED-500 Series. Both mount to a panic device already on the door and have no latch of their own, so neither replaces the Kwikset 400T Tylo, which is a complete cylindrical knob lock with its own 6AL latch and RCS strike.
19) Is there an antimicrobial knob option for a rental or care setting?
The Tylo 400T carries Microban, an antimicrobial treatment in the finish that resists bacterial growth on the surface. It is a touched-surface feature, useful in shared entries and turn-over units. It does not change how the lock functions or how it installs.
20) Which knob matches the traditional look of the Kwikset Tylo in a solid brass build?
The Tylo is a traditional round knob offered in Satin Nickel, Bright Chrome, Satin Chrome, Bright Brass, and Antique Brass. For the same round traditional profile in solid brass, the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection, and the Deltana 6901 Portland Knob entry fits 1-3/8 inch to 1-3/4 inch doors. The Omnia 434/PA is passage function, so it does not key.
21) Which knobsets come in multi-packs for standardizing several doors at once?
The Sure-Loc Bergen round knob is sold as a 6-pack with adjustable backset, which suits standardizing a run of openings in one order. The Kwikset 400T Tylo is a single keyed entry knob, so a fleet build with it is ordered per door in the finish and SmartKey configuration chosen.
