Master Lock DS0603KA4 – Frequently Asked Questions
1) Will the Master Lock DS06 deadbolt fit a door bored for a 2-3/8 inch backset, or do I need the 2-3/4?
Either one. The DS06 uses a four way adjustable latch that sets to a 2-3/8 inch (60mm) or 2-3/4 inch (70mm) backset, and the same latch converts between a square corner and a rounded corner faceplate. That covers both of the standard residential bore positions, so you don't have to measure the backset before you order, and one part number works across a building where some doors were drilled one way and some the other.
2) Can I get a Master Lock deadbolt that works on my existing Kwikset or Schlage keys?
The DS06 is built in three keyways: Kwikset KW1, Schlage C, and Weiser WR5. Pick the one that matches the keys already in the building and the new deadbolt runs on the same key system as the rest of the doors. There's also a keyed alike option at order time, so a set of them can all be cut to one key, and a key code field if the property already has a code on file.
3) Is a Grade 3 deadbolt enough for an apartment entry door, or do I need Grade 2 or Grade 1?
Grade 3 is the residential performance tier, and Master Lock rates the DS06 for exterior locking on an entry door. For a single-family rental or an owner-occupied home it's the normal spec. For a commercial opening, a multi-family common door, or any entrance that gets heavy daily traffic, step up: the Arrow DBX61 and Cal-Royal CB160 are Grade 2 single cylinder deadbolts, and the Dexter DB1000 single cylinder is Grade 1. Grade is a cycle and strength rating, not a keying difference, so you can move up a grade and stay on the same keyway family.
4) I need six deadbolts keyed alike for one property. Can I order the Master Lock DS06 that way?
Yes. Keying is a required choice on the DS06: keyed different is the standard, keyed alike puts every lock in the order on one key, and there's a less cylinder option if your locksmith is supplying and keying the cylinders. Keep all of them on the same keyway (KW1, Schlage C, or WR5) when you key them alike, and add your existing key code in the key code field if the property already runs one.
5) I need a deadbolt keyed on both sides instead of a thumbturn - what replaces the Master Lock DS06?
The Master Lock DS06 is single cylinder with a thumbturn inside, so it will not satisfy a double cylinder requirement. The Callan Model 210S is a Grade 3 double cylinder deadbolt, the Dexter DB2000 double cylinder is Grade 2 for doors 1-3/8 inch to 1-3/4 inch, and the Deltana 7312KA2 is a Grade 3 double cylinder for doors 1-3/8 inch to 2 inch. Double cylinder deadbolts require a key on the inside, which is restricted on egress doors in many jurisdictions.
6) Which single cylinder deadbolt should I specify if the opening requires a fire rated lock?
The Hager 3215 is a single cylinder deadbolt with a 1 inch throw, fire rated, cylinder x thumbturn, for doors 1-3/8 inch to 1-3/4 inch, and the Hager 3115 is a fire rated cylinder x thumbturn deadbolt with a Schlage C keyway over the same thickness range. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Master Lock DS06 is a Grade 3 residential single cylinder deadbolt for exterior entry doors.
7) What is a comparable Grade 3 single cylinder deadbolt with an adjustable backset if the Master Lock DS06 is not the right trim?
The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset, cylinder x thumbturn, fitting doors 1-3/8 inch to 1-3/4 inch. The Master Lock DS06 is also Grade 3 single cylinder with a four way adjustable backset covering 2-3/8 inch or 2-3/4 inch and square or rounded corner faceplates. Both are keyed outside with a thumbturn inside, so the swap keeps the same operation on an entry door.
8) Which deadbolt should I use instead of the Master Lock DS06 on a commercial opening that needs Grade 1?
The Master Lock DS06 is a Grade 3 deadbolt classified for residential use. Where a Grade 1 deadbolt is required, the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn for doors 1-3/8 inch to 1-7/8 inch, and the Accentra D111 is Grade 1 cylinder x thumbturn with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch. Both keep the key outside, thumbturn inside arrangement.
9) Can a deadlock or exit deadlock be used in place of a Master Lock DS06?
No. The Master Lock DS06 is a keyed single cylinder deadbolt with a thumbturn inside. The Arrow E60 is a Grade 2 exit deadlock that is non-keyed, blank plate outside x thumbturn inside, for doors 1-3/8 inch to 1-3/4 inch, so there is no outside key access. The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock, cylinder outside x blank inside, for doors 1-3/4 inch to 2-1/4 inch, so there is no inside turn. Neither reproduces the key outside plus turn inside operation of the DS06.
10) If I need a deadbolt in a Schlage C keyway from another maker, what are the options?
The Master Lock DS06 is offered in Kwikset KW1, Schlage C, and Weiser WR5 keyways. If the Schlage C keyway is the requirement, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder, and the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway - all three for doors 1-3/8 inch to 1-3/4 inch.
11) What deadbolt takes an interchangeable core instead of a conventional cylinder?
The Master Lock DS06 uses a conventional cylinder. Where a core-based keying program is in place, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core, supplied less cylinder, with a 2-3/4 inch backset, and the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 inch to 1-3/4 inch. The Delaney LM Series is a Grade 1 single cylinder less core deadbolt.
12) Which deadbolt matches a 2-3/4 inch backset only, without an adjustable option?
The Master Lock DS06 is four way adjustable for either a 2-3/8 inch or 2-3/4 inch backset, so it covers both preps. The Deltana CL200LA is a Grade 2 single cylinder deadbolt fixed at a 2-3/4 inch backset, and the Accentra D111 is a Grade 1 single cylinder deadbolt fixed at 2-3/8 inch. A fixed backset lock has to be ordered to match the hole already bored.
13) Is a surface or mortise deadbolt the same as a bored deadbolt like the Master Lock DS06?
No. The Master Lock DS06 is a bored deadbolt that installs through a cross bore in the door face with an adjustable 2-3/8 inch or 2-3/4 inch backset. The Codelocks CL200 is a surface deadbolt that mounts on the door face, the Emtek 2050 is a European mortise deadbolt with an integrated roller latch requiring a mortise pocket, and the Dormakaba D900 is a small case mortise deadbolt. Those need different door prep entirely.
14) Can I rekey the Master Lock DS06 deadbolt later, or is the cylinder fixed?
It's a conventional cylinder, so a locksmith can rekey it in place with standard pins for that keyway. What it isn't is small format interchangeable core, where you swap the core in seconds without disassembly. If you run an IC system across a property and want key control that way, look at an SFIC deadbolt like the Arrow E61 in SFIC prep less core, or the Deltana CL200LAIC interchangeable core deadbolt.
15) What's the closest alternative to the Master Lock DS06 if I want the same Grade 3 deadbolt from another brand?
Straight across at the same tier: the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset fitting 1-3/8 to 1-3/4 inch doors, and the Callan 200S is a Grade 3 single cylinder with square trim. If the thumbturn needs to be easier to grip for accessibility, the Cal-Royal LSD is a Grade 3 single cylinder with an ADA ergonomic thumbturn, same door thickness range. All three are cylinder by thumbturn, same basic function as the DS06.
16) The door only has a knob and no deadbolt hole. Can I add the DS06, or does it have to replace an existing bolt?
Either way. A deadbolt is a separate bore above the knob or lever, so the DS06 goes into an existing deadbolt prep or into a fresh bore drilled to Master Lock's template. Master Lock publishes an installation sheet for its Grade 3 deadbolts with the hole layout. If you're adding one where there is no bore at all and you'd rather not drill through both faces, a one sided half bore deadbolt like the Callan 205S is the version that only preps one side.
17) Will one Master Lock DS06 match the other deadbolts across my rental units?
It standardizes well for a residential portfolio: one model, four finishes, three keyways, and a four way adjustable backset that handles both the 2-3/8 inch and 2-3/4 inch bores you'll find across older and newer units. Order them keyed alike per unit or keyed different across the property, whichever your make ready process uses. Where a unit's opening is commercial rather than residential, or the door is fire labeled, that opening needs different hardware than a Grade 3 residential bolt.
18) What is the Grade 2 step up from a Grade 3 residential deadbolt for a rental turnover?
The Master Lock DS06 is Grade 3 single cylinder. For a Grade 2 deadbolt in the same cylinder x thumbturn function, the Dexter DB2000 single cylinder fits doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal CB160 adds a tamper-resistant cylinder guard, and the Arrow DBX61 is a Grade 2 single cylinder deadbolt. All three are keyed outside with a thumbturn inside like the DS06.
19) What Grade 3 deadbolt has an easier thumbturn to grip than a standard one?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, cylinder x thumbturn, for doors 1-3/8 inch to 1-3/4 inch. It sits at the same Grade 3 level as the Master Lock DS06 single cylinder deadbolt, so it is a like-for-like choice where the inside turn piece needs to be easier to operate.
20) Is the BEST 8T tubular deadbolt tube a substitute for a complete deadbolt?
No. The BEST 8T is a T Series tubular deadbolt tube component, meaning the latch case body rather than a finished lock. The Master Lock DS06 is a complete single cylinder deadbolt with the outside cylinder and inside thumbturn. Similarly, the Baldwin Reserve 8BR0618001 is a deadbolt spacer and the Arrow 460 is a mortise lock strike with latchbolt and deadbolt cutouts - both are parts that go with a lock, not locks.
21) What deadbolt do I use if the door will not take a full through-bore for a thumbturn side?
The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, so it works where only a partial bore is available. The Master Lock DS06 is a two-sided single cylinder deadbolt with a cylinder outside and thumbturn inside and needs the full bore. Both carry Grade 3.
22) What is a keypad or electronic alternative to a keyed residential deadbolt?
The Master Lock DS06 is a keyed single cylinder deadbolt with a conventional cylinder. If credentials rather than keys are wanted, 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. These change how the door is opened rather than the bolt function.
23) What single cylinder deadbolt has a square trim instead of round?
The Master Lock DS06 comes with square or rounded corners on a four way adjustable backset. If a square rose is the look required from another maker, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, cylinder x thumbturn, the Bravura 910005 is a Grade 2 rectangle single cylinder deadbolt, and the Brinks Mendocino is a contemporary square single cylinder deadbolt with a four way adjustable backset. The Callan Model 200S is a Grade 3 single cylinder square trim deadbolt.
24) What deadbolt should I use on a classroom door instead of a residential single cylinder?
The Master Lock DS06 is a Grade 3 residential single cylinder deadbolt. For classroom function, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, the Falcon D211 is a Grade 2 medium duty classroom deadbolt with single cylinder operation, and the Hager 3118 is a Grade 1 classroom deadbolt with a 6-pin cylinder for doors 1-3/8 inch to 1-3/4 inch.
25) I need a deadbolt and a knob or lever working together on the same door - what covers that?
The Master Lock DS06 is a deadbolt only, single cylinder with a thumbturn inside. The Falcon H2101 is a Grade 2 entrance interconnected lock that combines a single cylinder deadbolt with the latch trim, so one device covers both bores. The DS06 would be paired with a separate knob or lever set.
26) What thicker-door deadbolt works where a standard bored deadbolt will not fit?
The Master Lock DS06 is a bored single cylinder deadbolt for exterior entry doors. On thicker doors, the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt rated 1-3/8 inch to 2 inch, and the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock rated 1-3/4 inch to 2-1/4 inch. Confirm the door thickness at the bore before choosing.
27) What finishes does the Master Lock DS Series deadbolt come in?
Four: 605 bright brass, 609 antique brass, 716 aged bronze, and 619 satin nickel. Every one of those is built in all three keyways, so matching the finish to the other trim on the door never forces you off the key system you already have.
28) Which deadbolt do I choose for a decorative or higher-end residential entry instead of a standard Grade 3?
The Master Lock DS06 is a Grade 3 single cylinder deadbolt available in bright brass, antique brass, aged bronze, and satin nickel. For a decorative entry, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt in cylinder x thumbturn, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Baldwin Reserve contemporary round deadbolt is a double cylinder. Note the Baldwin options are keyed both sides rather than thumbturn inside.
