Kwikset 158RDT-15S.FD.DS.LK.23155 – Frequently Asked Questions

1) Will the Kwikset 158 Milan deadbolt fit my existing door prep, or do I need to drill a new hole?
The 6AL latch on the Kwikset 158 Milan is adjustable between a 2-3/8 inch and 2-3/4 inch backset, so it drops into either of the two standard door preps without redrilling the cross-bore. That covers essentially every standard residential door bored for a deadbolt.
2) Does the Kwikset 158 deadbolt key from both sides or just outside?
Key outside, thumbturn inside. It is a single cylinder deadbolt, so anyone on the interior can throw or retract the bolt by hand with no key. If you have glass in or beside the door and want to stop someone reaching through to turn it, you want a double cylinder instead, keyed both sides, such as the Baldwin Reserve Double Cylinder Contemporary Round Deadbolt or the Dexter DB2000 double cylinder.
3) Will the Kwikset 158 Milan deadbolt latch into the strike plate that's already on my frame?
It throws a 1 inch bolt and ships with its own round deadbolt strike plus a 5303 full lip strike, so you are not depending on what is in the frame now. If you keep the existing strike, the pocket behind it has to accept a full 1 inch of bolt, otherwise the bolt bottoms out and never fully throws. Swapping in the supplied strike is the cleaner install.
4) Is the Kwikset 158 deadbolt strong enough for a commercial building entry?
It is a residential lock, ANSI/BHMA Grade 2, which is the top residential grade but below what most commercial specs call for. For an apartment unit door, a rental house, or a back door on a small property, it is the right class of lock. For a commercial exterior opening or anything spec'd Grade 1, look at the Delaney LM Series Grade 1 single cylinder, the Deltana CL200LM Grade 1, or the Dexter DB1000 Series Grade 1 single cylinder instead.
5) What does SmartKey mean on this Kwikset deadbolt, and can I rekey it myself to match my other doors?
SmartKey lets you rekey the cylinder yourself in seconds with the existing key and a rekey tool, no cylinder removal and no locksmith. For a landlord turning units between tenants, that is the whole point: you rekey on site instead of scheduling a service call. It ships key coded and less key, so you supply the key code or bitting you want it cut to.
6) Can the Kwikset 158 Milan deadbolt go on a fire rated door?
It carries a 20 minute UL rating, which suits a 20 minute rated opening such as a typical apartment or condo unit entry door. It does not cover a 1 hour or 3 hour rated opening. If your door assembly is rated longer, the Cal-Royal CRB800 Grade 1 deadbolt uses a UL 3-hour fire rated latch.
7) Which products look like substitutes for the Kwikset 158RDT Milan deadbolt but are not?
The Kwikset 158RDT Milan is a complete keyed single cylinder deadbolt with latch and strike. Several deadbolt-named items serve a different purpose: the Arrow 460 is a mortise lock strike, not a lock; the Baldwin Reserve 8BR0618001 is a deadbolt spacer; the BEST 8T is a T Series tubular deadbolt tube component. The Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and thumbturn inside, so it takes no key at all, and the Callan 205S is a Grade 3 one sided half-bore deadbolt. The Falcon H2101 is an entrance interconnected lock rather than a standalone deadbolt.
8) What is the closest equivalent to the Kwikset 158RDT Milan single cylinder deadbolt from another brand?
The Kwikset 158RDT Milan is a Grade 2 single cylinder deadbolt, key outside and thumb turn inside, with a 1 inch throw and a latch adjustable from 2-3/8 inch to 2-3/4 inch backset. Peers built the same way include the Arrow DBX61, a Grade 2 cylinder x thumbturn deadbolt, and the Bravura 310B Elite, a Grade 2 traditional round deadbolt in cylinder x thumbturn. If the round rose profile is what you are matching, the Bravura 310RC Elite is a Grade 2 contemporary round deadbolt and the Callan 200S-G2 is a Grade 2 single cylinder round trim deadbolt.
9) I need a Grade 1 deadbolt instead of Grade 2 for a commercial opening - what should I use in place of the Kwikset 158RDT Milan?
The Kwikset 158RDT Milan carries ANSI/BHMA Grade 2 certification and is a residential product. For a Grade 1 single cylinder deadbolt in the same cylinder x thumbturn function, the Accentra D111 is Grade 1 with a 2-3/8 inch backset, the Dexter DB1000 single cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch thick, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. The Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset if you want the same backset flexibility the 158RDT latch gives you.
10) The opening needs a key on both sides - what replaces the Kwikset 158RDT Milan deadbolt?
The Kwikset 158RDT Milan is single cylinder: key outside, thumb turn inside. For key on both sides, the Hager 3214 is a Grade 2 double cylinder deadbolt for doors 1-3/8 inch to 1-3/4 inch thick, the Dexter DB2000 double cylinder is Grade 2 for the same thickness range, and the Delaney LU Series 320601 is a Grade 2 double cylinder in stainless steel US32D. In Grade 1, the Design Hardware D1 Series is an extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. Double cylinder deadbolts are restricted on egress doors in many jurisdictions, so confirm the code for the occupancy before specifying.
11) My doors are thicker than 1-3/4 inch - will the Kwikset 158RDT Milan work, or what should I order?
The Kwikset 158RDT Milan latch adjusts for backset, 2-3/8 inch to 2-3/4 inch, which is a different dimension from door thickness. For thick doors, the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch and is Grade 1, and the Deltana 7312KA2 double cylinder covers 1-3/8 inch to 2 inch in Grade 3. Both are deadbolt function.
12) I need to key the deadbolt into an existing Schlage C system - is the Kwikset 158RDT Milan the right choice?
The Kwikset 158RDT Milan uses Kwikset SmartKey. To match an existing Schlage C keyway across a building, 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 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw, the same throw as the 158RDT. For a small format interchangeable core system, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core, and the Deltana CL200LAIC is a Grade 2 interchangeable core deadbolt.
13) Which alternative to the Kwikset 158RDT Milan gives me the same backset flexibility across a mixed set of doors?
The Kwikset 158RDT Milan latch is adjustable from 2-3/8 inch to 2-3/4 inch, so one part covers both standard preps. Peers with the same flexibility include the Brinks Raleigh Series transitional round single cylinder deadbolt with a 4 way adjustable backset, the Brinks Mendocino Series square version with the same 4 way adjustable backset, the Cal-Royal ED500 Grade 3 with adjustable backset, and the Falcon D111 Grade 1 with adjustable backset. Fixed backset peers such as the Accentra D111 at 2-3/8 inch and the Deltana CL200LA at 2-3/4 inch have to be ordered per door prep.
14) The Kwikset 158RDT Milan is 20 minute UL rated - what if I need a longer fire rating?
The Kwikset 158RDT Milan carries a 20 minute UL rating. For longer rated openings, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch in cylinder x thumbturn function. Hager fire rated deadbolts are also available in this function: the 3115 Grade 2 and the 3215 Grade 2 single cylinder with a 1 inch throw, both for doors 1-3/8 inch to 1-3/4 inch thick.
15) Does the Kwikset 158 come with keys if it's ordered less key?
Two keys come in the box. The less-key, key-coded designation refers to how the cylinder is ordered against a code rather than the lock arriving without any keys.
16) What tools do I need to install a Kwikset 158 deadbolt, and does it need a special faceplate prep?
A screwdriver is all it takes. The latch has a round corner faceplate, which matches the routed pocket left by most factory-bored doors, so no chiseling of a square corner mortise is needed on a standard prep.
17) What's a comparable Grade 2 single cylinder deadbolt if I don't want SmartKey rekeying?
Several Grade 2 cylinder x thumbturn deadbolts cover the same function without SmartKey: the Arrow DBX61, the Cal-Royal CB160 with a tamper-resistant cylinder guard, the Bravura 310B Elite in traditional round trim, or the Hager 3215 with a 1 inch throw. The Hager 3215 also fits 1-3/8 to 1-3/4 inch doors, which is worth noting if you are standardizing across a mix of older interior and standard exterior doors.
18) What is a lower cost alternative to the Kwikset 158RDT Milan deadbolt for interior or light traffic doors?
The Kwikset 158RDT Milan is Grade 2 certified. Where a lighter duty rating is acceptable, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for doors 1-3/8 inch to 1-3/4 inch thick, and the Callan 200S is a Grade 3 single cylinder square trim deadbolt. Both are cylinder x thumbturn like the 158RDT. Step down only where the door does not need Grade 2 durability - the 158RDT is rated for exterior keyed entry use.
19) I want a keypad or electronic deadbolt instead of the keyed Kwikset 158RDT Milan - what are the options?
The Kwikset 158RDT Milan is a mechanical deadbolt operated by key outside and thumb turn inside. For code or credential entry, 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 Codelocks CL200 is a light duty surface deadbolt with key override. For multifamily RFID credentials, the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt.
20) I need a classroom function deadbolt rather than the Kwikset 158RDT Milan - what covers that?
The Kwikset 158RDT Milan is a residential keyed entry deadbolt with a thumb turn inside. For institutional classroom function, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt, the Falcon D211 is the Grade 2 medium duty classroom version, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder for doors 1-3/8 inch to 1-3/4 inch. Where the inside must have no thumb turn at all, the Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in cylinder x blank for 1-3/4 inch doors.
21) Is there an alternative to the Kwikset 158RDT Milan with an easier to grip thumbturn for accessibility?
The Kwikset 158RDT Milan locks with a turn piece on the interior. Where an accessible operator is required, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch thick, in the same cylinder x thumbturn function.
22) What deadbolt should I use instead of the Kwikset 158RDT Milan if the door is prepped for a mortise case rather than a bored hole?
The Kwikset 158RDT Milan installs in a standard bored deadbolt prep with an adjustable 2-3/8 inch to 2-3/4 inch backset latch. For mortise preps, the Dormakaba D900 is a small case mortise deadbolt in cylinder x thumbturn, keyed different with SC keyways, the Dormakaba M1960 is an M1000 Series single cylinder deadbolt in cylinder x thumbturn with no trim, and the Emtek 2051 is a European mortise deadbolt with an integrated roller latch in a round profile, with the 2050 as the square version.
23) Is there a deadbolt like the Kwikset 158RDT Milan with added protection against cylinder attack?
The Kwikset 158RDT Milan is a Grade 2 single cylinder deadbolt with a 1 inch throw and a round deadbolt strike. Where the cylinder needs additional protection, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard in the same cylinder x thumbturn function. For openings needing more than a single bolt point, the Detex DX Series is a hinge side locking deadbolt with multi-point security.
24) What finishes does the Kwikset Milan round rose deadbolt come in?
Three: Satin Nickel, Bright Chrome, and Matte Black. Satin Nickel and Bright Chrome will read closest to existing brushed and polished builder hardware on a fleet of doors; Matte Black is for matching newer black trim packages. All three are the same round rose trim, so mixing them across a building is a look decision, not a fit one.
25) Can I use the Kwikset 158 Milan deadbolt on an interior door or a garage-to-house door?
It is built for exterior doors where keyed entry and security matter, and that is where the 1 inch throw and Grade 2 rating earn their keep. Nothing stops it going on a garage-to-house or storage room door bored for a deadbolt, provided the prep takes a 2-3/8 or 2-3/4 inch backset.
26) What is a higher end decorative alternative to the Kwikset 158RDT Milan deadbolt?
The Kwikset 158RDT Milan is a Signature Series deadbolt offered in Satin Nickel, Bright Chrome, and Matte Black. For decorative trim in the same single cylinder cylinder x thumbturn function, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt. In double cylinder, the Baldwin Reserve contemporary round and contemporary square deadbolts and the Emtek 8323 Modern Disc in brass cover the same design intent, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in entrance function.
