Lockey 3830-SCMG – Frequently Asked Questions

1) Will the Lockey 3830 keyless knob lock fit a 1-3/4 inch commercial door?
Yes. The Lockey 3830 covers a door thickness range of 1 3/16 inch to 2 inches, so a standard 1-3/4 inch commercial door sits mid-range. Thicker openings are handled with an extension kit that takes it up to 5 inch doors, which is what gets it onto gate posts and clad exterior doors.
2) Can the Lockey 3830 go into the existing holes when I pull off an old knob lock?
In most cases yes. The 3830 covers a standard 2 1/8 inch bore, and the trim plates give a total coverage footprint of 7 inches by 2 1/2 inches, so it hides the marks and cutouts an older cylindrical knob left behind. The latch backset is adjustable, so you don't have to know whether the door was prepped at 2-3/8 or 2-3/4 inches before you order.
3) Do I need to order a left hand or right hand version of the Lockey 3830?
No handing to specify. The 3830 is reversible in the field, so one part number covers both left and right hand doors. For a property manager stocking a few spares across a building, that means one shelf item instead of two.
4) What is the difference between the single combination and double combination Lockey 3830?
That's the ordering decision on the 3830. Single combination gives one user code on the outside. Double combination is the two-sided configuration, for openings where you want a code required from both directions rather than free egress on the inside. Both are offered in every finish: Jet Black Marine Grade, Satin Chrome Marine Grade, Oil-Rubbed Bronze, and Satin Nickel.
5) Does the Lockey 3830 keyless lock need batteries or wiring?
Neither. The 3830 is a mechanical pushbutton lock, so there is no power, no battery to change, and nothing to fail when the building loses power. The code is set in the lock itself, with thousands of possible combinations for the one user code. For an MRO or facilities buyer, that removes the battery replacement cycle an electronic keypad brings with it.
6) Does the Lockey 3830 latch on its own when the door closes?
It does. The 3830 uses a mechanical deadlocking spring latch that auto-locks on close, so the door is secure the moment it shuts rather than waiting for someone to throw a bolt. Inside, it works as a passage function, so leaving is a straight knob turn with no code.
7) The opening is a fire rated door - can the Lockey 3830 be swapped in, or is another knob lock needed?
For a fire rated knob opening, the Falcon X101 Grade 1 heavy duty cylindrical passage knobset and the Falcon W101 Grade 2 medium duty passage/closet knob lock with a 2-3/4 inch backset both carry a fire rating. The Lockey 3830 is a commercial mechanical keyless combination knob with zinc-plated steel construction; specify one of the fire rated Falcon knobsets when the door assembly rating governs the hardware.
8) What is the closest keyed-alternative to the Lockey 3830 keyless knob lock if a facility wants to keep using keys?
The Lockey 3830 is a mechanical keyless combination knob lock with a passage function and one user code, so there is no key or cylinder to manage. If a keyed cylinder is wanted on the same knob-style opening, the Corbin Russwin CK4851 is a Grade 1 entrance/office cylindrical lock with a global knob and a conventional cylinder, and it fits doors 1-3/8 inch to 2 inch thick, which overlaps most of the 1 3/16 inch to 2 inch range the 3830 covers. The tradeoff is key management: the CK4851 opening is controlled by cylinder keying, the 3830 opening by a combination.
9) The spec calls for an ANSI/BHMA Grade 1 knob lock on a passage opening - what meets that instead of the Lockey 3830?
For a Grade 1 passage knob, the Falcon X101 is a heavy duty Grade 1 cylindrical passage knobset with an interchangeable core, fire rated, for doors 1-3/8 inch to 2-1/4 inch thick. The Schlage D10S is a Grade 1 heavy duty non-keyed passage latch with an orbit knob, and the Corbin Russwin CK4310 is a Grade 1 non-keyed passage/closet cylindrical lock with a global knob for doors 1-3/8 inch to 2 inch. The Lockey 3830 is the mechanical keyless combination knob with a passage function, so it is the choice when the opening needs code control rather than a graded passage latch.
10) Which knob lock should be used instead of the Lockey 3830 on a storeroom door that has to stay locked at all times?
The Lockey 3830 is a passage-function keyless knob, so the outside knob is released by entering the combination. A storeroom function keeps the outside knob locked at all times and is opened by a cylinder key: the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, and the Sargent 6G04 is the Grade 2 standard duty storeroom/closet knob lock with a single cylinder. Choose the 3830 when the goal is to eliminate keys on the opening, and a storeroom lock when the door must never be free-passage.
11) What knob lock covers a door thicker than 1-3/4 inches if the Lockey 3830 does not suit the opening?
The Lockey 3830 itself covers 1 3/16 inch to 2 inch doors, with an extension kit available for doors up to 5 inches. Among conventional knob locks, the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 Grade 1 passage/closet covers 1-3/8 inch to 2 inch, and the Deltana 6171 Round Knob entry covers 1-3/8 inch to 2 inch. Common knob locks such as the Arrow MK01 Grade 2 passage and the Dexter C2000 passage knob stop at 1-3/4 inch.
12) Which finish should I pick for a Lockey 3830 going on an outside gate or a coastal building?
Go with one of the marine grade options, Jet Black Marine Grade or Satin Chrome Marine Grade. Both are the corrosion-resistant treatments in the range. Oil-Rubbed Bronze and Satin Nickel are the other two choices and read better on interior or sheltered openings. The lock body itself is zinc-plated steel with Teflon coated stainless interior parts, which is what lets it live outdoors at all.
13) How much room does the Lockey 3830 need on the door face and how far does it stick out?
The lock body measures 6 5/16 x 1 3/4 x 2 1/4 inches, and with trim plates the coverage on the door face is 7 by 2 1/2 inches. That matters on narrow stile doors and on openings with a closer arm or a jamb-mounted device nearby, where you need to know what the pushbutton housing will occupy before you drill.
14) Is there a keyed knob lock I should use instead of a Lockey 3830 keyless one?
If you actually want a key on the opening, the choice is a conventional cylindrical knob lock. The Corbin Russwin CK4851 is a keyed entrance/office knob lock with a conventional cylinder that covers 1-3/8 to 2 inch doors. The Sargent 8XG04 is a Grade 1 storeroom knob lock with a 2-3/4 inch backset if you want the door always locked outside and keyed access only. The 3830 is the option when you want to stop managing keys entirely and hand out a code instead.
15) I just need a knob on a hallway or closet door with no security. Is the Lockey 3830 overkill?
Yes, for a plain hall or closet door you want a straight passage knobset, not a combination lock. The Dexter C2000 Series passage ball knob and the Corbin Russwin CK4310 Grade 1 passage knob both do that job on 1-3/8 to 1-3/4 inch and 1-3/8 to 2 inch doors respectively. The 3830 earns its place where the door has to be secured behind whoever walks through it and you don't want to issue keys.
16) What is a simpler knob lock to use instead of the Lockey 3830 on an interior door that does not need access control?
The Lockey 3830 is built around a combination keypad with auto-locking, which is more than an interior hall or closet door needs. For a plain latching knob on that kind of opening, the Corbin Russwin CK4410 is a Grade 2 non-keyed passage/closet cylindrical lock with a global knob for doors 1-3/8 inch to 1-3/4 inch, and the Dexter C2000 passage ball knob is a Grade 2 non-clutching non-keyed passage lock for the same 1-3/8 inch to 1-3/4 inch range. Both latch and release without any code; the 3830 keeps the keyless code control and the 1 3/16 inch to 2 inch thickness range.
17) Will a dummy knob such as the Schlage A170 or BEST 6K work in place of the Lockey 3830?
No. The Schlage A170 is a Grade 2 single dummy trim knob and the BEST 6K single dummy trim is a Grade 2 medium duty dummy knob; a dummy knob is fixed trim with no latch and no locking of any kind. The Lockey 3830 is a mechanical deadlocking spring latch with auto-locking and a combination code, so it actually latches and secures the door. Dummy trim is for an inactive leaf or a pull-only door.
18) What knob lock gives privacy for a restroom or bedroom door where the Lockey 3830 combination knob is not appropriate?
A privacy knob locks from the inside with a thumbturn or button and has no code entry. The Dexter C2000 privacy ball knob is Grade 2 non-keyed for doors 1-3/8 inch to 1-3/4 inch, the Cal-Royal BER20 is a Grade 3 privacy knob with brass trim for the same range, and the Pamex FTF Baron privacy knob is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. The Lockey 3830 is a keyless combination knob with a passage function, which suits controlled access rather than occupant privacy.
19) For an exterior gate or coastal door, what knob lock competes with the Lockey 3830?
The Lockey 3830 is built for exterior and interior use with zinc-plated steel and Teflon coated stainless steel interior components, and it comes in Jet Black and Satin Chrome marine grade finishes alongside Oil-Rubbed Bronze and Satin Nickel. The knob locks in the comparable range are graded cylindrical locksets specified by function and door thickness, such as the Corbin Russwin CK4310 Grade 1 passage for 1-3/8 inch to 2 inch doors and the Schlage D10S Grade 1 heavy duty passage latch. Where the opening is outdoors and salt exposure is the driver, the 3830 marine grade finishes are the reason to stay with it.
20) Is a keyed entry knob like the Kwikset 400P-CP the same thing as the Lockey 3830?
No. The Kwikset 400P-CP is a Grade 3 keyed entry Polo knob for doors 1-3/8 inch to 1-3/4 inch, supplied with a round corner adjustable latch and round corner strike, and it is opened with a key. The Lockey 3830 opens on a mechanical combination with one user code and no key, fits 1 3/16 inch to 2 inch doors, and has a reversible handing with an adjustable backset latch. They look similar on the door but are managed completely differently.
21) For standardizing an entrance opening across a facility, what heavy duty knob lock is the alternative to the Lockey 3830?
The BEST 8K Series entrance function single cylinder knob lock is Grade 1 heavy duty, which supports facility-wide standardization on a keyed entrance knob. The Callan Edgewood is a Grade 2 entrance knobset and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for doors 1-3/8 inch to 1-3/4 inch. The Lockey 3830 is the keyless route for the same opening, standardizing on a combination instead of a keyway.
22) Is the Lockey 3830 built for commercial traffic or is it a residential lock?
Commercial. The 3830 is rated for commercial use, with zinc-plated steel construction and Teflon coated stainless interior components. It goes on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and municipal buildings, and works interior or exterior.
