Lockey D-ADJ – Frequently Asked Questions

1) Does the Lockey D-ADJ keyless deadbolt need batteries or wiring?

No power of any kind. The Lockey D-ADJ is a mechanical digital deadbolt, so the code is entered on a mechanical keypad and the bolt is driven by hand. Nothing to wire, no batteries to change, and no dead lock when the building loses power. That is the main reason it gets specified on gates, storage rooms, and outbuildings where running power to the door is not practical. If you want an electronic deadbolt instead, ZenSupply carries the Codelocks CL2200 electronic surface deadbolt and the Delaney KP400 electronic deadbolt with programmable remote.

2) Can I change the code on a Lockey mechanical digital deadbolt without replacing the lock?

Yes. The D-ADJ uses a programmable digital combination, so the code can be changed when a tenant moves out or a contractor finishes on site. For a property manager that is the practical difference against a keyed deadbolt: no rekeying visit and no chasing keys that were copied. Where you do want a key on the door as well, a keyed cylinder deadbolt like the Arrow DBX61 or the Hager 3215 is the different animal, those are cylinder-and-thumbturn locks that have to be rekeyed to change access.

3) Should I use a keyless mechanical deadbolt or a keyed cylinder deadbolt on a shared access door?

It comes down to who needs in and how often that changes. A mechanical digital deadbolt like the Lockey suits doors with rotating users, trades, cleaners, seasonal staff, where you would otherwise be handing out and collecting keys. A keyed deadbolt suits doors that belong on the building's key system so one master opens everything. If you need the door keyed into an existing system, look at a cylinder x thumbturn deadbolt such as the Accentra D111, a Grade 1 unit with a 2-3/8 inch backset, or the Hager 3118 Grade 1 classroom deadbolt with a Schlage C keyway.

4) My opening needs a fire rated deadbolt - is the Lockey D-ADJ the right choice?

For a fire rated opening, look at deadbolts that carry a fire rating in their listing. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder, fire rated, for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3215 is a single cylinder Grade 2 commercial deadbolt with a 1 inch throw, also fire rated, over the same door thickness range. The Cal-Royal CRB800 is a heavy duty single cylinder x thumbturn deadbolt with a UL 3-hour fire rated latch in the CRB800 Series. These are keyed cylinder deadbolts, so credential management moves from a code to the building key system.

5) What is a keyed equivalent to the Lockey D-ADJ mechanical digital deadbolt for an opening that has to accept a key?

The Lockey D-ADJ is a keyless mechanical digital deadbolt that opens on a pushbutton code rather than a key. When the opening has to work with an existing key system instead, the Dexter DB1000 Series single cylinder deadbolt is a Grade 1 cylinder x thumbturn deadbolt covering 1-3/8 inch to 1-7/8 inch doors, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt in the D Series with a 2-3/8 inch backset. Both throw a deadbolt into the same style of prep but require a key or a keyed cylinder on the outside face, so the credential becomes a key rather than a code.

6) What keyless deadbolt should I use instead of the Lockey D-ADJ if I want a code lock with a key override?

The Lockey D-ADJ operates purely on a mechanical digital combination with no electrical power involved. If the opening needs a code plus a key bypass for management access, the Codelocks CL200 is a surface deadbolt with key override in the CL200 Series, rated light duty. That combination lets staff enter on the code while a supervisor or locksmith retains a keyed path in, which the code-only D-ADJ does not provide.

7) Is an electronic keypad deadbolt a substitute for the Lockey D-ADJ?

They solve the same access problem differently. The Lockey D-ADJ is mechanical: the digital combination is entered on a mechanical mechanism, so there is no power source, battery, or wiring to maintain. Electronic alternatives include the Codelocks CL2200 electronic surface deadbolt in the CL2000 Series, rated medium duty, the Codelocks CL2210 electronic mortise deadbolt, and the Delaney KP400 Grade 2 electronic deadbolt with programmable remote. Those add electronic credential management and, on the KP400, remote operation, while the D-ADJ keeps working during a power or battery failure.

8) I need a deadbolt that keys into an interchangeable core system - what do I use instead of the Lockey D-ADJ?

The Lockey D-ADJ is code-operated and does not take a cylinder, so it stands outside a keying system. For an opening that must fall into an SFIC or interchangeable core program, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep, supplied less core, for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 single cylinder x thumbturn deadbolt prepped for an interchangeable core with a 2-3/4 inch backset. Both let the facility keying stay under one core program. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D if the spec calls for Grade 1.

9) The spec on my drawing calls for a Grade 1 deadbolt - what fits that where the Lockey D-ADJ is being considered?

Where an institutional spec names ANSI/BHMA Grade 1, keyed Grade 1 deadbolts in the set include the Design Hardware D1 Series double cylinder deadbolt, extra heavy duty, for 1-3/4 inch doors; the Falcon D111 Grade 1 classroom deadbolt with adjustable backset, heavy duty, in the D100 Series; the Corbin Russwin DL3011 Grade 1 cylindrical deadlock, cylinder x blank, for 1-3/4 inch to 2-1/4 inch doors; and the Deltana CL200LM Grade 1 single cylinder x thumbturn deadbolt. All of these are keyed cylinder products rather than code entry, so the access method changes along with the grade.

10) What looks like a substitute for the Lockey D-ADJ but will not work on a standard bored deadbolt prep?

Several deadbolt-named parts in the same family install differently. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket rather than a bored hole. The Dormakaba D900 is a small case mortise deadbolt. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, a frame part rather than a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer and the BEST 8T is a T Series tubular deadbolt tube component, both pieces of a lock rather than a complete one. None of these replaces a complete keyless deadbolt on their own.

11) What deadbolt do I use instead of the Lockey D-ADJ when the door must not be openable from the inside without a key?

The D-ADJ is a code-entry deadbolt and is not a double cylinder product. Where a glass-front or sidelight door requires a key on both faces so a broken pane does not give access to a thumbturn, double cylinder deadbolts in the set include the Dexter DB1000 Series Grade 1 double cylinder for 1-3/8 inch to 1-7/8 inch doors, the Design Hardware D1 Series Grade 1 extra heavy duty double cylinder for 1-3/4 inch doors, and the Hager 3214 Grade 2 double cylinder with a Schlage C keyway, fire rated, for 1-3/8 inch to 1-3/4 inch doors. Confirm the local egress code permits a double cylinder on the opening before specifying one.

12) For a multifamily property standardizing on credential-based entry, what are the alternatives to the Lockey D-ADJ?

The Lockey D-ADJ gives every unit a changeable digital code with no batteries or wiring, which keeps turnover simple across a fleet of doors. If the property wants credentials managed centrally instead, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt in the Nova Series and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override in the Saffire Series. Those move access to cards and phones with an audit path; the D-ADJ keeps the code in the lock itself and needs no network or power infrastructure.

13) Is the Lockey D-ADJ rated for commercial use or is it a residential lock?

Commercial. Lockey lists the D-ADJ as a commercial-duty deadbolt, and it is used on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and municipal buildings. The stainless steel core construction is the part that carries that duty rating on a high traffic opening.

14) What does the free-spinning stainless steel core on the Lockey deadbolt actually do?

It defeats drill and torque attacks on the outside trim. The core shaft is stainless steel and spins free, so an attacker turning or drilling at the outside face is not transmitting anything to the bolt mechanism. On an exterior or perimeter opening that is the attack a keyless lock has to survive, since there is no cylinder to pick but there is still a shaft behind the keypad.

15) Is the Lockey D-ADJ a full deadbolt or just a latch?

Full deadbolt function. It throws a deadbolt, not a spring latch, so the door is positively locked rather than held closed. That matters if you are comparing it against keypad latch products like the Codelocks CL160 mortise latch, which is a latch-function light duty unit, or the Codelocks CL200 surface deadbolt, which is also light duty. The Lockey is the commercial-duty option of the keyless mechanical group.

16) Can I put a keyless code deadbolt on a door that also needs a key override for staff?

The Lockey D-ADJ is code entry only, no cylinder. If your policy needs a physical key as a backup, the Codelocks CL200 surface deadbolt is a code lock built with key override. Another route property managers take is a separate keyed deadbolt on the same opening, cylinder x thumbturn units like the Deltana CL200LA with a 2-3/4 inch backset are commonly used for that.

17) What is the difference between the Lockey D-ADJ and a thumbturn-only deadbolt like the Arrow E60?

Both give you a deadbolt with no key on the outside, but they control different sides of the door. The Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate on one side and a thumbturn on the other, fitting doors 1-3/8 inch to 1-3/4 inch thick, so it only locks and unlocks from the secure side and there is no way in from the outside. The Lockey D-ADJ accepts a programmable digital combination from the outside face, so an authorized person can enter without a key. Choose the E60 when the outside must stay blind and the D-ADJ when coded entry is needed.

18) Is there a simpler deadbolt than the Lockey D-ADJ for a light-traffic residential door?

The Lockey D-ADJ is built for commercial use. For a lower-traffic opening where a plain keyed deadbolt is enough, the Cal-Royal ED500 is a Grade 3 single cylinder x thumbturn deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Callan Model 200S is a Grade 3 single cylinder deadbolt with square trim. The Bravura 310B Elite is a Grade 2 traditional round deadbolt, cylinder x thumbturn, if a step up in grade is wanted. All three are key-operated, so residents carry keys instead of a code.

19) Which deadbolt handles a thicker door than usual when the Lockey D-ADJ will not suit?

For openings above the common 1-3/4 inch leaf, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch doors and the Deltana 7312KA2 double cylinder deadbolt is a Grade 3 heavy duty unit covering 1-3/8 inch to 2 inch. Both are keyed cylinder deadbolts. On standard-thickness commercial leaves, the Dexter DB2000 Series single cylinder Grade 2 covers 1-3/8 inch to 1-3/4 inch.

20) What replaces the Lockey D-ADJ when the deadbolt has to be released electrically from a remote point?

The D-ADJ is entirely mechanical and is thrown and retracted at the door. Where access control has to release the bolt from a card reader or front desk, the DynaLock 1300 Series is a heavy duty mortise electric deadbolt. The Detex DX Series is a hinge side locking dead bolt with multi-point security for openings that need the leaf secured at more than one point. Both change the door prep, so verify the frame and leaf can take a mortise or multi-point installation.

21) I need a deadbolt with an adjustable backset like the Lockey D-ADJ - which keyed models offer that?

Keyed deadbolts in the set that adjust to more than one backset include the Falcon D111, a Grade 1 heavy duty classroom deadbolt with adjustable backset in the D100 Series; the Cal-Royal ED500, a Grade 3 single cylinder x thumbturn with adjustable backset for 1-3/8 inch to 1-3/4 inch doors; and the Brinks Raleigh Series E2401 and Mendocino Series E2402 single cylinder deadbolts, both with a 4-way adjustable backset in round and square trim respectively. An adjustable backset lets one part number cover doors already bored at either common dimension.

22) Is a classroom function deadbolt the same thing as the Lockey D-ADJ?

No. The Lockey D-ADJ is a keyless deadbolt where anyone holding the current code can throw or retract the bolt. Classroom function deadbolts such as the Falcon D111, Grade 1 heavy duty in the D100 Series, the Falcon D211, Grade 2 medium duty in the D200 Series, and the Hager 3118 Grade 1 with Schlage C keyway restrict operation to a keyholder, which is the point when a teacher or staff member is supposed to be the only one able to secure the room. Choose by who is meant to hold control, not by the bolt itself.

23) The door already has a lockset and only needs the deadbolt added - what are the options next to the Lockey D-ADJ?

The Lockey D-ADJ is a standalone deadbolt that adds code entry above an existing latch. If the plan is instead to combine latch and bolt in one unit, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt in the H2 Series, which handles both from one trim and retracts them together. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt for a door where only the inside face gets a bolt and no through-bore is wanted.

24) What is the Lockey LOCD-ADJ deadbolt replacement part for?

It is the deadbolt assembly itself for Lockey mechanical digital locks, ordered as the replacement unit rather than a complete new lock package. Buyers who already run Lockey keypads across a site use it to swap out the bolt hardware and keep the existing keypad in service. Stainless steel is the material.
