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

1) Can the Sure-Loc DB201 be keyed to my existing Schlage keys?
Yes, if you specify it. The DB201 comes standard with a 5-pin KW1 (Weiser/Kwikset) keyway, and a 5-pin SC1 Schlage keyway is available instead. Choose SC1 if the rest of the building runs Schlage-keyed hardware and you want the new bolt on the same key. This is the choice to get right at order time, because the keyway is not something you swap on site without a cylinder change.
2) Is the Sure-Loc Modern Square deadbolt keyed on both sides?
No, it's cylinder by thumbturn: key outside, thumbturn inside. That's the right setup for a solid entry door, but it's the wrong choice next to glass sidelites or a glass-panel door, where someone can break the glass and turn the bolt by hand. For those openings you want a double cylinder, keyed both sides, such as the Baldwin Reserve Contemporary Square Deadbolt or the Emtek 8323 Modern Disc, both keyed on the interior as well.
3) Is a Sure-Loc DB201 deadbolt strong enough for an apartment building or a school door?
It's a residential-duty deadbolt, listed for residential use, with a forged brass housing and a cut-resistant bolt carrying hardened steel rolling inserts that spin against a saw blade. That build handles a house or a single-family rental. For a commercial opening under real traffic or a spec that calls out a grade, go to a graded commercial bolt instead: the Cal-Royal CRB800 heavy duty single cylinder, the Design Hardware D1 Series (Grade 1, extra heavy duty), or the Dexter DB1000 (Grade 1).
4) I need a square trim deadbolt but with an ANSI grade for a spec - what else is square?
The Sure-Loc DB201 carries a modern square style. For square trim with a published grade, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt in cylinder x thumbturn, the Callan Model 200S is a Grade 3 single cylinder square trim deadbolt, and the Bravura Rectangle deadbolt is a Grade 2 single cylinder with rectangular trim if a stretched square shape suits the door better. The Brinks Mendocino contemporary square single cylinder deadbolt also uses square trim and has a 4 way adjustable backset.
5) What is a commercial equivalent to the Sure-Loc DB201 modern square deadbolt for a rental unit that needs a graded deadbolt?
The Sure-Loc DB201 is a residential single cylinder deadbolt with a cylinder x thumbturn function and a solid forged brass housing. If the opening calls for a graded commercial deadbolt in the same cylinder x thumbturn function, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset, and the Dexter DB1000 single cylinder deadbolt is Grade 1 and covers doors 1-3/8 to 1-7/8 inches thick. Both keep the key outside and thumbturn inside arrangement, so the daily operation for a tenant is unchanged.
6) What should I use instead of the Sure-Loc DB201 on a glass-adjacent or sidelite door where a key is needed on both sides?
The Sure-Loc DB201 is a single cylinder deadbolt, key outside and thumbturn inside, so it is not the choice when the inside must also be keyed. Double cylinder options in the same tubular deadbolt family include the Dexter DB1000 double cylinder, which is Grade 1 for doors 1-3/8 to 1-7/8 inches, the Dexter DB2000 double cylinder at Grade 2 for 1-3/8 to 1-3/4 inch doors, and the Baldwin Reserve Contemporary Square double cylinder deadbolt if the square trim look matters. Check local egress code before specifying double cylinder on a dwelling exit door.
7) What deadbolt should I specify instead of the Sure-Loc DB201 on a fire rated opening?
The Sure-Loc DB201 is a residential deadbolt with a cut resistant bolt and hardened steel rolling inserts. When the drawing calls for a fire rated deadbolt, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw and carries a fire rating for doors 1-3/8 to 1-3/4 inches, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway and a fire rating over the same thickness range, and the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
8) The Sure-Loc DB201 is offered in KW1 and SC1 keyways. What deadbolt already comes in a Schlage keyway or takes an interchangeable core?
The Sure-Loc DB201 is available with a 5 pin KW1 or 5 pin SC1 cylinder. If the building is keyed to a Schlage system, the Hager 3115 and Hager 3214 both use a Schlage C keyway, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder. If the site runs small format interchangeable cores instead, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 to 1-3/4 inches, and the Deltana CL200LAIC is a Grade 2 single deadbolt prepped for an interchangeable core with a 2-3/4 inch backset.
9) What finish should I pick to match the rest of the door hardware on a Sure-Loc Modern Square deadbolt?
Six finishes cover it: 11P Vintage Bronze, 15 Satin Nickel, 26 Polished Chrome, 32D Satin Stainless, FBL Flat Black, and SB Satin Brass. Flat black and satin stainless are the usual pair on a modern square trim package; vintage bronze and satin brass read warmer against a stained door. If you're matching existing levers across a building, match the finish code rather than the finish name, since bronze and brass names vary by maker.
10) Is the Emtek 2050 square mortise deadbolt a substitute for the Sure-Loc DB201 square deadbolt?
No. The Sure-Loc DB201 is a tubular deadbolt with an adjustable 2-3/8 to 2-3/4 inch backset that installs into a standard bored door prep. The Emtek 2050 is a European mortise deadbolt with an integrated roller latch in square trim, and the Emtek 2051 is the same lock in round trim. A mortise lock needs a pocket cut into the door edge, so it is not a drop-in for a bored deadbolt prep even though the square trim looks similar.
11) I do not need a key on this door, just a thumbturn to lock it from inside. What replaces the Sure-Loc DB201?
The Sure-Loc DB201 is keyed, with a cylinder outside and a thumbturn inside. Where no key is wanted, the Arrow E60 is a non-keyed Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, for doors 1-3/8 to 1-3/4 inches. If the door only needs to lock from one side with no through-bore, the Callan Model 205S is a Grade 3 one sided half-bore deadbolt.
12) Is the Sure-Loc DB201 the same thing as a classroom function deadbolt?
No. The Sure-Loc DB201 is a cylinder x thumbturn deadbolt, so the inside always turns free to retract the bolt. A classroom function deadbolt operates differently: the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset and the Falcon D211 is the Grade 2 medium duty version, both in the D Series family. The Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock with a cylinder outside and a blank inside for 1-3/4 inch doors, which removes inside thumbturn operation entirely.
13) What alternative to the Sure-Loc DB201 has an easier thumbturn for accessibility?
The Sure-Loc DB201 uses a modern square thumbturn on the inside. Where the turn needs to be easier to grip, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 to 1-3/4 inches, which is the same thickness range the DB201 covers. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset over that same range if the ergonomic turn is not required.
14) What replaces the Sure-Loc DB201 if I want keypad or credential entry instead of a key?
The Sure-Loc DB201 is a non-electronic mechanical deadbolt. For credential entry on the same door, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and an electronic lock override. A surface deadbolt such as the CL2200 mounts to the face of the door rather than into a bored prep, so confirm the door prep before switching.
15) What is the Sure-Loc DB201 deadbolt actually made of?
The housing is solid forged brass, and the internals run stainless steel substrate. Forged brass rather than cast or stamped is what resists a wrench attack on the exterior rose, and the bolt itself is cut resistant with hardened steel rolling inserts set into it, so a hacksaw blade spins the insert instead of biting. Brass under a plated finish also holds up better on a coastal or high-humidity exterior door than plated zinc.
16) Is the Sure-Loc Modern Square deadbolt a keypad or smart lock?
No, it's fully mechanical: key outside, thumbturn inside, no batteries and no electronics. If you want code or phone access on the same opening, the Delaney KP400 is an electronic deadbolt with a programmable remote, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with Bluetooth and an electronic lock override.
17) The Sure-Loc DB201 comes in flat black and satin nickel. What comparable deadbolts come in a decorative or cast finish?
The Sure-Loc DB201 is offered in Vintage Bronze, Satin Nickel, Polished Chrome, Satin Stainless, Flat Black, and Satin Brass over a solid forged brass housing. For a heavier decorative look in the same single cylinder cylinder x thumbturn function, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt if the inside can be keyed. The Emtek 8323 Modern Disc is a brass double cylinder deadbolt for a modern round face.
18) Can the Sure-Loc DB201 be used where a deadbolt needs to be combined with a latching entrance lock?
The Sure-Loc DB201 is a standalone deadbolt with no latch, so a separate knob or lever set has to carry the latching. If a single interconnected unit is preferred, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt built in, which retracts both the latch and the bolt from the inside in one motion. That is a different door prep than two separate bores.
