Sure-Loc DB201-MD 11P – Frequently Asked Questions

1) Will the Sure-Loc Modern Round deadbolt fit a 1-3/8 inch interior door and a 1-3/4 inch entry door?
Both. The DB201 deadbolt is built for doors 1-3/8 to 1-3/4 inches (35-45mm) thick, which covers the standard 1-3/4 inch exterior door and the thinner 1-3/8 inch door common on older interiors. No spacer kit is needed inside that range.
2) Does this Sure-Loc deadbolt work with a 2-3/8 or a 2-3/4 inch backset bore?
Either one. The Modern Round DB201 uses an adjustable latch that sets to 2-3/8 inch or 2-3/4 inch (60-70mm) backset, the two standard bored-door backsets, so you don't have to know which prep the door has before ordering. Handing is reversible as well.
3) Can I get a batch of these Sure-Loc deadbolts all on one key?
Yes. Keying is a no-cost selection at order time: Keyed Alike or Keyed Different. Keyed alike is supplied in sets of 4, so if you're doing a duplex or a row of units, order in multiples of four to keep a single key working across the group.
4) Can the Sure-Loc Modern deadbolt be keyed to my existing Schlage keys?
There is a keyway choice on the DB201: 5 Pin KW1 (the standard, Kwikset/Weiser style) or 5 Pin SC1, which is the Schlage residential keyway. Pick SC1 if the rest of the building is already on Schlage residential keys.
5) Is this a single cylinder deadbolt with a thumbturn inside, or keyed both sides?
Key outside, thumbturn inside. The DB201 is a cylinder x thumbturn single cylinder deadbolt, so it retracts from the inside without a key. If you need key operation on both faces (for a door with glass nearby, where local code allows it), a double cylinder unit such as the Baldwin Reserve Contemporary Round Deadbolt or the Dexter DB2000 double cylinder is the version to look at.
6) Is the Sure-Loc Modern Round deadbolt suitable for a commercial or institutional opening?
It's a residential-duty deadbolt, sold under the Sure-Loc Modern collection for houses and apartment entries. For a commercial or institutional door, step up to a graded commercial unit: the Accentra D111 or Deltana CL200LM are Grade 1 cylinder x thumbturn deadbolts, and the Arrow DBX61 or Cal-Royal CB160 are Grade 2 options.
7) What is the closest contemporary round single cylinder deadbolt to the Sure-Loc Modern Round DB201 from another brand?
The Bravura 310RC Elite is a contemporary round deadbolt with the same cylinder x thumbturn function, and it carries a Grade 2 rating. The Sure-Loc Modern Round DB201 is a residential cylinder x thumbturn deadbolt with a solid forged brass housing, adjustable 2-3/8 inch to 2-3/4 inch backset, and fits doors 1-3/8 inch to 1-3/4 inch thick. If the round contemporary rose shape is what you are matching, those two are the nearest pair; if you want a squared rose instead, the Bravura 310SC Elite is the same Grade 2 cylinder x thumbturn deadbolt in a contemporary square trim.
8) I need a Grade 1 deadbolt for a commercial opening - what should I use instead of the Sure-Loc Modern Round DB201?
The Sure-Loc Modern Round DB201 is classified residential. For 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 inch to 1-3/4 inch thick, the Dexter DB1000 single cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch, and the Falcon D111 is a heavy duty Grade 1 cylinder x thumbturn with an adjustable backset. All three cover the same door thickness range the Sure-Loc handles.
9) The Sure-Loc Modern Round deadbolt has a thumbturn inside - what do I use on a glass-panel door where I need key operation from both sides?
A thumbturn next to glass can be reached through a broken lite, so those openings usually take a double cylinder. The Sure-Loc Modern Round DB201 is cylinder x thumbturn only. For a keyed-both-sides equivalent in a round contemporary trim, the Baldwin Reserve Contemporary Round is a double cylinder deadbolt; the Dexter DB2000 double cylinder is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, and the Dexter DB1000 double cylinder is Grade 1 for doors 1-3/8 inch to 1-7/8 inch. Confirm your local code permits double cylinder on that door before ordering.
10) Which deadbolt should I specify instead of the Sure-Loc Modern Round if the door needs a fire rating?
The Hager 3115 and Hager 3215 are single cylinder deadbolts in a Schlage C keyway that carry a fire rating and fit doors 1-3/8 inch to 1-3/4 inch, the same thickness range the Sure-Loc Modern Round DB201 covers. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Sure-Loc DB201 is a residential deadbolt, so for a labeled opening go with one of those.
11) My master key system uses small format interchangeable cores - can I still use the Sure-Loc Modern Round deadbolt?
The Sure-Loc Modern Round DB201 ships with a 5 pin KW1 or 5 pin SC1 cylinder, not an interchangeable core. For an SFIC system, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC less core for doors 1-3/8 inch to 1-3/4 inch, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt for interchangeable core with a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt.
12) Can I swap the Sure-Loc Modern Round DB201 into a 2-inch thick door?
No. The Sure-Loc Modern Round DB201 fits doors 1-3/8 inch to 1-3/4 inch thick. For a thicker door, the Deltana 7312KA2 double cylinder deadbolt covers 1-3/8 inch to 2 inch, and the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch. The Dexter DB1000 single cylinder reaches 1-7/8 inch if you only need a little more range with a thumbturn inside.
13) What is the Sure-Loc Modern deadbolt made of, and how does it hold up to attack?
The housing is solid forged brass over a stainless steel substrate, and the bolt is cut resistant with hardened steel rolling inserts, which is what defeats a hacksaw blade on the bolt itself. Brass construction also means the finish is plated on metal, not a coated zinc casting.
14) I need a modern square-trim deadbolt instead of round. What else is there?
The DB201 is round rose trim only. For square or rectangular modern trim, the Bravura 310SC Elite and Callan 200S are Grade 3 or Grade 2 square-trim single cylinder deadbolts, and the Brinks Mendocino E2402 is a contemporary square single cylinder with a 4-way adjustable backset.
15) The Sure-Loc Modern Round deadbolt has a round rose - what is an equivalent in a square or rectangular trim?
For squared trim in the same cylinder x thumbturn function, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Bravura Rectangle is a Grade 2 single cylinder rectangle deadbolt, and the Brinks Mendocino is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. The Sure-Loc Modern Round DB201 itself is offered only in the round modern trim, across Vintage Bronze, Satin Nickel, Polished Chrome, Satin Stainless, Flat Black and Satin Brass.
16) Is the Sure-Loc Modern Round DB201 the same thing as the Emtek 2051 Round mortise deadbolt?
No. The Sure-Loc Modern Round DB201 is a bored deadbolt that fits standard residential door prep with an adjustable 2-3/8 inch or 2-3/4 inch backset. The Emtek 2051 is a European mortise deadbolt with an integrated roller latch in a round trim, which requires a mortise pocket in the door edge rather than a bored crossbore. They are not interchangeable in an existing door without re-prepping.
17) I want the Sure-Loc Modern look but on an interior door with no key - what is the alternative?
The Sure-Loc Modern Round DB201 is keyed with a cylinder outside and a thumbturn inside. For a non-keyed opening, the Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, for doors 1-3/8 inch to 1-3/4 inch. If you want a thumbturn on one face only with a half-bore prep, the Callan 205S is a Grade 3 one-sided deadbolt.
18) What is a simpler single cylinder deadbolt than the Sure-Loc Modern Round DB201 for a rental turn?
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, and the Callan 200S is a Grade 3 single cylinder deadbolt in a square trim. Both share the cylinder x thumbturn function of the Sure-Loc Modern Round DB201. The Sure-Loc differs in having a solid forged brass housing and a cut resistant bolt with hardened steel rolling inserts, and it can be ordered keyed alike in sets of 4.
19) I need an ADA-friendly thumbturn - does the Sure-Loc Modern Round deadbolt have one, or is there a better option?
The Sure-Loc Modern Round DB201 uses a modern round thumbturn on the interior. If the specification calls out an ergonomic turn piece, 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, the same thickness range the Sure-Loc covers.
20) If I want a keypad instead of a key on the same door, what replaces the Sure-Loc Modern Round DB201?
The Sure-Loc Modern Round DB201 is a mechanical, non-electronic deadbolt. For coded or credential access on a comparable opening, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL200 is a surface deadbolt with key override, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
21) Is the Bravura 310B Elite a drop-in match for the Sure-Loc Modern Round deadbolt?
Functionally it is close - the Bravura 310B Elite is a Grade 2 single cylinder deadbolt with the same cylinder x thumbturn function - but its trim is a traditional round rose rather than the modern round styling of the Sure-Loc DB201. On a fleet of doors where the rose profile has to match, the Bravura 310RC Elite contemporary round is the closer visual pick.
22) Is the Sure-Loc DB201 a keypad or smart deadbolt?
No, it's mechanical and key operated only, with no electronics. If you want code or credential entry on a deadbolt, look at the Delaney KP400 electronic deadbolt or the Codelocks CL2200 electronic surface deadbolt.
