Lockey 3835-JB – Frequently Asked Questions

1) Will the Lockey 3835 keyless lever lock fit my door thickness?
The 3835 mechanical keyless lever fits doors from 1 3/16 inch up to 2 inches as supplied, which covers both the 1-3/8 inch older interior door and the 1-3/4 inch standard commercial door. Past 2 inches you need Lockey's optional Extension Kit, which takes it out to 5 inches for thick or clad exterior doors. It also covers a standard 2 1/8 inch bore, so a door already prepped for a cylindrical lockset takes it without new boring.
2) Does the Lockey 3835 need batteries or wiring?
No power at all. The 3835 is a purely mechanical pushbutton lock, so there is no battery to change, no transformer, and no wire to pull to the door. The code is entered on the keypad and the deadlocking spring latch does the work. That is the trade for what an electronic lock gives you: no audit trail, no remote unlock, no scheduling, and one user code rather than a list of them. If you need per-user codes or an audit log, an electronic keypad leverset like the Delaney LP250 is the other direction to go.
3) Is a keyless pushbutton lever the right choice for a classroom or storeroom door, or do I need a keyed lockset?
The 3835 controls entry by code, not by key, so nobody carries a key and you rekey by changing the combination. That suits shared doors, tenant storage, mechanical rooms and back entrances where keys go missing. What it does not do is give you a keyway that ties into an existing master key system, and it does not carry a keyed classroom or storeroom function. If you need to stay on a facility keyway, a keyed lever like the Cal-Royal AG03 classroom lever on a 2-3/4 inch backset or the Cal-Royal AG05 Grade 2 storeroom lever with a deadlocking latchbolt is the right family instead.
4) What is the closest keyless pushbutton alternative to the Lockey 3835 lever lock?
Within the mechanical pushbutton family, the Codelocks CL410 and CL415 use a tubular latchbolt in the CL400 Series and are the nearest code-entry lever alternative that also runs without batteries or wiring. The Lockey 3835 differs in that it is an auto-locking lever with passage function, a deadlocking spring latch, and a single user code with thousands of possible combinations, offered in single or double combination configurations. If the opening needs a code-entry lever and the crew wants no power run, both are mechanical; the choice comes down to whether you want the auto-locking behavior with a passage override or a straight tubular latchbolt platform.
5) If I want a keypad lever but need electronic code management instead of a mechanical one, what should I look at?
The Delaney LP250 electronic keypad leverlock, a Grade 2 lock in the LP250 Series, is the electronic counterpart when codes need to be managed electronically rather than set on a mechanical wheel pack. The Lockey 3835 is a mechanical keyless lever that operates with no batteries or electrical connections, carrying one user code with thousands of possible combinations. For a gate, a remote outbuilding, or any opening where nobody wants a battery-change route, the mechanical 3835 is the one that runs unpowered; where a facility wants electronic code handling, the LP250 is the keypad lever to spec.
6) What should I use instead if the opening is on a fire-rated door?
Fire door openings need a lever the manufacturer rates for that use. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with a fire rating, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever in the CL3100 Series that is also fire rated. If the opening needs to be keyed rather than passage, the Arrow MK02-TA is a fire-rated privacy cylindrical lock. The Lockey 3835 is the mechanical keyless lever for exterior and interior commercial openings where a code-entry lever is what the job calls for.
7) We want key control on this door rather than a shared code. What is the equivalent keyed lever?
For a keyed storeroom opening, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt covering 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever covering 1-3/8 inch to 2 inch. For entry/office keyed function, the Dexter C1000 Series entry/office lever is Grade 1 and covers 1-3/8 inch to 1-3/4 inch. Those put the door on a keyway and a key system; the Lockey 3835 runs on one user code with thousands of possible combinations, so access changes by rekeying the code rather than by issuing keys.
8) Is a passage leverset the same thing as a keyless lever lock?
No, and this is the most common wrong swap. The Falcon B101 is a Grade 2 medium duty cylindrical passage lever, the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors, and the Arrow GL01 is a Grade 2 Sierra lever passage lock for 1-3/4 inch to 2 inch doors. A passage function lever always retracts from both sides and never secures the opening. The Lockey 3835 has auto-locking with a passage mode override, so it can be put into free passage during business hours and returned to secured operation without swapping hardware.
9) What is the difference between single combination and double combination on the Lockey 3835?
That is the choice you make on the order form, and it changes how the lock is used day to day. Single combination gives you one code that unlocks the lever. Double combination adds a second code, which is how you run a passage-mode setup: one code for normal entry, the other to hold the lock in passage so the lever stays free during business hours. Both are offered in all four finishes.
10) How much room does the Lockey keyless lever take up on the door face?
The lock body measures 6 5/16 x 1 3/4 x 2 1/4 inches, and with the trim plates the total footprint is 7 x 2 1/2 inches. Check that against narrow stiles and against any adjacent closer arm, panic hardware or vision-lite frame before you commit, since the keypad body is taller than a conventional rose trim.
11) What does auto-locking with passage function actually mean on a Lockey lever lock?
Auto-locking means the lever relocks on its own after each entry, so a door left to swing shut is secured without anyone having to remember to lock it. Passage function is the override: put it in passage and the lever stays free both ways, which is how you run a door open through the workday and let it secure itself at close. That combination is the reason it goes on tenant entries, break rooms and back-of-house doors that are public during hours and locked after.
12) How does the Lockey 3835 compare to a standard Grade 1 or Grade 2 commercial passage lever?
Different jobs. A cylindrical passage lever such as the Falcon K101 Grade 1 or the Corbin Russwin CL3110 Grade 1 vandal-resistant passage lock never latches against anyone, it just retracts the latch; those are for doors that only need to close, not secure. The 3835 secures the door by code and relocks itself, with a deadlocking spring latch. Note the door prep differs in range too: the Corbin CL3110 is a 1-3/4 to 2 inch device, while the Lockey starts at 1 3/16 inches, so the Lockey is the one that goes on thinner gate and older interior doors.
13) Does the keyless lever need to be handed like the Baldwin dummy levers?
No. The Lockey 3835 has reversible handing and an adjustable backset latch, so one part number covers both left and right hand openings. That is not true across the peer set: Baldwin Estate 5103 half dummy levers are ordered by hand, with separate left hand and right hand part numbers on the 5048 rose. Some cylindrical peers are also built non-handed, such as the Falcon B101 Grade 2 passage lever and the Falcon K101 Grade 1 passage lock, both described with non-handed levers. For a property manager stocking spares across a mixed fleet of doors, a reversible lever means one shelf item instead of two.
14) Can I use a dummy lever on the outside of the door and put the keyless lock inside?
A dummy trim has no latch at all. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim, the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim, and the Baldwin Estate 5103 half dummy lever with 5048 rose is a dummy in the same lever family. Those are surface trims for inactive leaves and closet fronts. The Lockey 3835 is a complete lever lock with a deadlocking spring latch and an adjustable backset latch, covering a standard 2 1/8 inch bore, so it is the working half of the opening, not a companion trim.
15) What is a simpler lever for the interior doors if only the exterior door needs code entry?
Interior hall and closet doors behind a code-controlled entrance are usually done with plain passage levers. The Hager 2510 is a Grade 2 passage cylindrical lever covering 1-3/8 inch to 2 inch, the Accentra 5301LN Augusta is a Grade 2 passage/closet lever in the 5300 Series, and the Callan Asheville is a Grade 3 passage leverset in satin nickel. Pairing those inside with the Lockey 3835 on the exterior leaf keeps one code at the point of entry, and the 3835 is available in satin nickel as well as oil rubbed bronze, satin chrome marine grade, and jet black marine grade if the interior trim needs to match.
16) Which lever holds up better outdoors on a gate or exterior service door?
The Lockey 3835 is built with a zinc-plated steel housing and Teflon-coated stainless steel interior components for weather-resistant performance in exterior and interior applications, and it is offered in jet black marine grade and satin chrome marine grade finishes. The commercial cylindrical peers in the same category are specified for interior door use by function rather than by environment: the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever. For gates, pool enclosures, yard doors, and unconditioned exterior openings, the 3835 is the one carrying the weather-resistant construction and marine grade finishes.
17) For a classroom or a utility room, is the keyless lever the right choice or do I need a specific function?
Those openings usually call for a named function lock. The Dexter C1000 Series classroom lever is Grade 1 keyed and covers 1-3/8 inch to 1-3/4 inch doors, with a classroom security version in the same series, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility lock with a conventional cylinder in the Schlage C keyway. Those are specified when a facility standard names the function. The Lockey 3835 is the keyless auto-locking lever with passage override for commercial openings controlled by a code, such as storage rooms, mechanical spaces, and staff entrances where issuing keys is the problem being solved.
18) Is the Lockey 3835 rated for commercial use or is it a residential lock?
Commercial. It is specified as a commercial lock and it is a lever, not a knob, which is what most commercial and multi-family openings call for. The zinc-plated steel body is what carries the traffic. It goes into office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and municipal facilities.
