Kwikset 158RDT-26DS.STRKP – Frequently Asked Questions

1) Will the Kwikset 158RDT-S Milan deadbolt fit my existing door prep, or do I need to know the backset first?
The 158RDT-S ships with the 6AL adjustable latch, so it covers both standard residential backsets, 2-3/8 inch and 2-3/4 inch, without ordering a separate latch. Those are the two backsets you'll find on nearly every residential entry door, so you can measure from the door edge to the center of the bore after the fact and still be right. The STRKP strike pack is in the box for the frame side.
2) Is the Kwikset Milan 158RDT-S keyed on both sides or does it have a thumbturn inside?
Single cylinder: key outside, thumbturn inside. That's the right choice for a standard entry door, and it's what most fire and egress guidance prefers because nobody needs a key to get out. If you specifically want key access on both sides, for a door with glass beside it, you'd move to a double cylinder deadbolt instead, like the Callan 210S or the Dexter DB2000 double cylinder.
3) Can I re-key the Kwikset 158RDT-S myself so all my rentals use one key?
Yes, and that's the main reason property managers buy this one. The Milan 158RDT-S has SmartKey Security, so you re-key it in seconds with the SmartKey tool rather than pulling the cylinder or calling a locksmith. Buy the deadbolts in the finish you want, then key them all alike yourself as units turn over. Most competing deadbolts of this class have no owner re-key function at all.
4) Is the Kwikset Milan deadbolt strong enough for a commercial building or an apartment entry?
The 158RDT-S is ANSI/BHMA Grade 2 and is built as a residential deadbolt. That's fine for single-family, condo and light multi-family unit doors. For a commercial opening, a building entrance, or anything taking heavy daily traffic, step up to a Grade 1 deadbolt such as the Accentra D111, the Design Hardware D1 Series, or the Dexter DB1000. Grade 1 is the top ANSI/BHMA durability tier and is what most commercial specs call for.
5) Can the Kwikset 158RDT-S replace an existing deadbolt without re-drilling the door?
On a door that already carries a standard residential tubular deadbolt, yes. The adjustable 6AL latch matches either 2-3/8 inch or 2-3/4 inch backset, which covers the standard bore layouts, and the STRKP strike pack lets you redo the frame side if the old strike doesn't line up. Where it won't drop in is a mortise deadbolt prep, a pocket cut into the door edge rather than a round bore; that needs a mortise unit like the Emtek 2051 European mortise deadbolt or the Dormakaba D900 small case mortise deadbolt.
6) I need a deadbolt on a fire rated door - does the Kwikset 158RDT-S Milan work there?
For a fire rated opening, specify a deadbolt whose fire rating is stated. The Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and a fire rating, fitting 1-3/8 to 1-3/4 inch doors, and the Hager 3115 is a Grade 2 cylinder x thumbturn with a Schlage C keyway and the same fire rating and thickness range. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The 158RDT-S Milan is a residential Grade 2 deadbolt.
7) What is the closest equivalent to the Kwikset 158RDT-S Milan round rose deadbolt from another brand?
The Bravura 310RC Elite is the nearest match in form and function: a contemporary round deadbolt rated ANSI/BHMA Grade 2 with cylinder x thumbturn operation, the same keyed-outside, turn-inside arrangement the 158RDT-S Milan uses at the same Grade 2 rating. If a round rose in a more traditional profile suits the door better, the Bravura 310B Elite is also Grade 2 cylinder x thumbturn. For a square trim instead of round, the Bravura 310SC Elite carries the same Grade 2 cylinder x thumbturn build.
8) The Kwikset 158RDT-S is residential Grade 2 - what do I use on a commercial opening that needs Grade 1?
Step up to a Grade 1 single cylinder deadbolt. The Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset and fits doors 1-3/8 to 1-3/4 inch thick. The Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn across a 1-3/8 to 1-7/8 inch door thickness range. The Deltana CL200LM is a Grade 1 single cylinder deadbolt, and the Delaney LM Series is Grade 1 single cylinder supplied less core for an interchangeable core keying program. The 158RDT-S itself is a Grade 2 residential deadbolt.
9) My exit door has glass next to it - what deadbolt should I use instead of a single cylinder like the Kwikset 158RDT-S?
A single cylinder deadbolt such as the 158RDT-S has a thumbturn on the inside, which can be reached through adjacent glass. A double cylinder deadbolt is keyed on both sides instead: the Dexter DB2000 double cylinder is Grade 2, the Hager 3214 is a Grade 2 double cylinder with a Schlage C keyway, and the Callan 210S is Grade 3 double cylinder. For heavy commercial glass openings, the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder for 1-3/4 inch doors. Confirm your local egress code permits a keyed inside cylinder before specifying one.
10) The Kwikset 158RDT-S uses SmartKey re-keying - what should I specify instead for a facility on an interchangeable core keying program?
SmartKey on the 158RDT-S re-keys the lock itself with a SmartKey tool, which is a different program from small format interchangeable core. For SFIC, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep supplied less core, for 1-3/8 to 1-3/4 inch doors. The Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core with a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. Ordering less core lets your locksmith load the facility's existing core.
11) What finishes does the Kwikset 158RDT-S Milan deadbolt come in?
Five: Venetian Bronze, Satin Nickel, Satin Chrome, Bright Chrome and Matte Black. If you're matching existing hardware in a building, Satin Nickel and Venetian Bronze are the two that pair with most builder-grade levers already hung; Matte Black is the one to pick when the door furniture has already been switched to black. The round Milan rose keeps the look plain, so it sits under a variety of trim styles.
12) Do I need anything else to install the Kwikset Milan 158RDT-S, or is it complete out of the box?
Complete. The 158RDT-S includes the 6AL adjustable latch and the STRKP strike pack, and it installs with just a screwdriver. If the door isn't already bored, you'll need a standard deadbolt bore kit; on a door that already had a deadbolt, this drops into the existing prep and no drilling is needed.
13) Is the Kwikset 158RDT-S handed, or does it work on a left and right swing door?
Deadbolts aren't handed. The 158RDT-S installs the same on a left-hand or right-hand door, inswing or outswing, because the bolt throws straight into the frame and the round Milan rose has no orientation to it. All you're matching is bore, backset and door thickness.
14) Should I buy a SmartKey deadbolt like the Kwikset Milan or an electronic keypad deadbolt?
It depends on who needs access and how often that changes. The 158RDT-S is a mechanical single cylinder deadbolt with SmartKey, so you keep a physical key but can re-key it yourself in seconds, no batteries and nothing to program. If you're handing out codes to tenants, cleaners or contractors and want to change them remotely, look at an electronic deadbolt such as the Delaney KP400 with programmable remote or the Dormakaba Saffire LX-D RFID deadbolt instead.
15) What is a comparable single cylinder Grade 2 deadbolt if I don't want the Kwikset SmartKey cylinder?
Several Grade 2 cylinder-by-thumbturn deadbolts cover the same function without SmartKey. The Arrow DBX61, the Cal-Royal CB160 with a tamper-resistant cylinder guard, and the Bravura 310RC Elite contemporary round deadbolt are all Grade 2 single cylinder units. If you need the lock keyed to an existing Schlage C system rather than the Kwikset keyway, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt supplied in Schlage C.
16) Is there a lighter duty round deadbolt than the Kwikset 158RDT-S Milan for a low traffic door?
For interior or low traffic openings, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset covering 1-3/8 to 1-3/4 inch doors, and the Cal-Royal LSD is Grade 3 single cylinder with an ADA ergonomic thumbturn for occupants who have trouble gripping a standard turn. The Callan 200S is Grade 3 single cylinder with square trim. All three are cylinder x thumbturn like the 158RDT-S Milan, which is Grade 2.
17) Will the Arrow 460 or a Baldwin deadbolt spacer work as a replacement for the Kwikset 158RDT-S Milan deadbolt?
No - neither is a deadbolt. The Arrow 460 is a mortise lock strike with a straight lip for latchbolt and deadbolt functions, so it is the frame-side piece, not the lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer, and the BEST 8T is a T Series tubular deadbolt tube component, both parts that go into or behind a lock rather than replacing one. If you need a complete keyed deadbolt with trim, latch and strike, compare against a full single cylinder unit such as the Arrow DBX61, a Grade 2 cylinder x thumbturn deadbolt, rather than these components. The 158RDT-S ships with its 6AL adjustable latch and STRKP strike pack.
18) What else offers an adjustable backset like the Kwikset 158RDT-S 6AL latch if I do not know the door's bore spacing yet?
The 158RDT-S ships with the 6AL latch, which sets to either 2-3/8 or 2-3/4 inch backset. The Brinks Raleigh Series round single cylinder deadbolt and the Brinks Mendocino Series square single cylinder deadbolt both use a 4-way adjustable backset, and the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors. Fixed-backset alternatives pin you to one dimension: the Accentra D111 is built for a 2-3/8 inch backset and the Deltana CL200LA for 2-3/4 inch, so those need the bore measured first.
19) What deadbolt do I use on a classroom door instead of the Kwikset 158RDT-S?
Classroom function deadbolts are a separate build. 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 equivalent with single cylinder operation. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for 1-3/8 to 1-3/4 inch doors. The 158RDT-S Milan is a residential deadbolt.
20) I want keyless entry instead of the Kwikset 158RDT-S keyed deadbolt - what are the options?
For code or credential entry, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. The Codelocks CL200 is a light duty surface deadbolt with key override, and the CL2200 is a medium duty electronic surface deadbolt. For multifamily and hospitality credential systems, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Nova-D is an RFID multihousing smart electronic deadbolt. The 158RDT-S is a keyed mechanical deadbolt with SmartKey re-keying, so it needs no power or programming.
21) The door only bores from one side and I cannot key it - can I still use something like the Kwikset 158RDT-S?
No, the 158RDT-S needs a through bore for the outside key cylinder and inside turn piece. For a door prepped one side only, the Callan 205S is a Grade 3 one-sided half-bore deadbolt. If the opening needs thumbturn-only operation with no key at all, the Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on the outside and a thumbturn inside, for 1-3/8 to 1-3/4 inch doors.
22) My door is thicker than standard - which deadbolt covers it if the Kwikset 158RDT-S does not?
For an oversized door, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock covering 1-3/4 to 2-1/4 inch door thickness, the widest range in the comparable group. The Deltana 7312KA2 is a Grade 3 heavy duty double cylinder deadbolt for 1-3/8 to 2 inch doors. If the door is a standard 1-3/4 inch, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock built for that thickness.
23) Is there a Grade 2 alternative to the Kwikset 158RDT-S with a cylinder guard against wrenching?
The Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, cylinder x thumbturn like the 158RDT-S Milan, which is also Grade 2. For a multipoint approach on the hinge side rather than the lock edge, the Detex DX Series provides hinge side locking deadbolts with multi-point security.
24) I want the same round contemporary deadbolt look but in a square rose. What else is there?
The Milan on the 158RDT-S is a round rose. For the same contemporary read in a square trim, the Bravura 310SC Elite is a Grade 2 square deadbolt and the Brinks Mendocino Series is a contemporary square single cylinder with a 4-way adjustable backset. Both are cylinder-by-thumbturn like the Milan, so the function on the door is identical and only the trim shape changes.
25) What matches the Kwikset 158RDT-S Milan deadbolt if I want a decorative round rose in solid brass or bronze?
For decorative round trim, the Emtek 2051 is a European mortise deadbolt with an integrated roller latch in a round profile, cylinder x thumbturn, and the Emtek #11 Tuscany is a lost wax cast bronze deadbolt, also cylinder x thumbturn. The Baldwin Reserve Contemporary Round is a double cylinder round deadbolt if you want keyed both sides in a round rose. The 158RDT-S Milan round rose comes in Venetian Bronze, Satin Nickel, Satin Chrome, Bright Chrome and Matte Black.
