Lockey M230-SC – Frequently Asked Questions

1) Will the Lockey M230 keyless lock fit a 1-3/8 inch wood door?
Yes. The M230 covers a door thickness range of 1-1/8 inch to 2 inches as standard, so 1-3/8 inch interior doors and 1-3/4 inch commercial doors are both inside the normal range with no extra parts. Outside that band, Lockey offers optional kits that take the lock down to 1/8 inch thick doors and up to 5 inches thick, which is what you need for gates, glass frame stiles, or thick insulated exterior doors.
2) Can the Lockey M230 combination lock go into an existing 2-1/8 inch bore without redrilling the door?
It drops straight into a standard 2-1/8 inch cross bore, which is the same prep a knob or lever leaves behind, so a keyed knob coming off a door is a direct swap in most cases. The edge bore is 1 inch. The body measures 4 7/8 x 1 1/2 x 1 3/4 inches. The one thing to check is backset: the M230 uses an adjustable backset latch, so it sets to what the existing hole gives you rather than forcing you to pick 2-3/8 or 2-3/4 up front.
3) Does the Lockey M230 need batteries or wiring?
Neither. The M230 is a purely mechanical push-button lock, so it keeps working through a power outage and there is nothing to wire, no transformer, and no battery to change on a service schedule. For a property manager running a fleet of doors, that removes the recurring maintenance visit that battery keypads generate.
4) Is the Lockey M230 handed, or can I use one lock on both left and right hand doors?
Handing is field-changeable on the M230, so a single lock covers left hand and right hand openings and you do not need to stock two versions. That matters if you are standardizing across a building where the door swings are mixed.
5) Can I use the Lockey M230 on an exterior door or a gate?
Yes, it is built for outside use. The housing is zinc-plated steel and the interior components are Teflon coated stainless steel, which is what keeps the mechanism moving after weather exposure. There is also a Marine Grade finish option if the door is coastal or near a pool deck. For gates specifically, check the leaf thickness against the 1-1/8 inch to 2 inch standard range, and use the optional thickness kit if the frame is thinner or thicker than that.
6) Does the Lockey M230 lock automatically when the door shuts, or do I have to press something?
It self-locks. The M230 uses a deadlocking spring latch, so it relatches every time the door closes behind someone, with no button to press and nothing for a tenant to forget. The deadlocking feature also resists the latch being carded back. Both the outside and inside have knob operation, so you get code entry outside and free knob egress inside.
7) The opening needs a fire-rated latch. Can I use the Lockey M230?
The M230 is a mechanical keyless combination lock in zinc-plated steel with Teflon coated stainless steel interior components, built for commercial exterior and interior openings and rated by Lockey for weather exposure. Where the specification calls for a fire rating, the Accentra YSSL10 security sidelite auxiliary latch carries a fire rating and is built for 1-3/4 inch doors, and it includes an ADA compliant thumbturn. Note the YSSL10 is a sidelite auxiliary latch, so it suits a narrow sidelite or a secondary point rather than the main knob-operated opening the M230 serves.
8) What should I use instead of a Lockey M230 if the door needs a deadbolt rather than a spring latch?
The M230 throws a deadlocking spring latch that engages automatically when the door closes, with a long throw bar extending 2-1/4 inches and a short throw bar extending 7/8 inch. If the opening calls for a true deadbolt latch instead, the Schlage 12-289 fits the B500 Series with an adjustable 2-3/8 or 2-3/4 inch backset and a 1 inch x 2-1/4 inch face with 1/4 inch round corners, and the Schlage 12-630 fits the B600, 700 and 800 Series with a 2-3/8 inch backset and a 1-1/8 inch x 2-1/4 inch square corner face. Match the face size and corner style to the existing door prep so you are not chiseling the edge.
9) What is a keyed alternative to the Lockey M230 for an opening that needs a Grade 1 entry latch instead of a keyless code?
The Lockey M230 is a mechanical keyless combination lock with a deadlocking spring latch and knob operation on both sides, so entry is by user code rather than by key. If the opening needs a keyed entry latch instead, the Deltana G1RLE238 is a Grade 1 regular latch with an entry function in a 2-3/8 inch backset, and the Deltana G1RLE275 is the same Grade 1 entry latch in a 2-3/4 inch backset. Pick the Deltana backset that matches the existing bore-to-edge dimension in the door; the M230 uses an adjustable backset latch instead of a fixed one.
10) Is a Schlage 16-480 deadlatch a substitute for a Lockey M230?
No. The Schlage 16-480 is a deadlatch for the S200 Series with an adjustable 2-3/8 or 2-3/4 inch backset and a 1 inch x 2-1/4 inch face with square corners; it is the latch component that goes with a lockset, not a complete locking device. The Lockey M230 is a self-contained keyless combination lock with its own knobs on the exterior and interior and a deadlocking spring latch built in. Order the 16-480 when you are replacing the latch inside a Schlage S200 lockset, and the M230 when you need the whole lock.
11) What is the difference between single combination and double combination on the Lockey M230?
That is the ordering choice you make on the M230. Single combination programs one user code. Double combination gives you a second code, which is how you separate a tenant code from a contractor or staff code on the same door without rekeying anything. Both are offered in every finish the M230 comes in, so the choice does not restrict your finish.
12) Which throw bar do I need with the Lockey M230, the long or the short one?
Two throw bars come into play with the M230: the long bar extends 2 1/4 inches and the short bar extends 7/8 inch. The bar length has to suit how far the latch has to reach from the lock body to the strike on your particular prep, which is why the adjustable backset and two bar lengths go together. Match the bar to the backset the existing hole in the door gives you.
13) I just need a plain deadlatch, not a keyless combination lock. What should I get instead of the Lockey M230?
If the code entry is not what you are after, and you just want a latch to pair with existing trim, a straight replacement deadlatch is the cheaper move. The Schlage 16-480 deadlatch for the S200 Series is adjustable to 2-3/8 or 2-3/4 inch backset with a 1 x 2-1/4 inch square corner face. The Dexter Grade 1 Deadlatch for the C1000 Series is another. Deltana's G1RLE Grade 1 regular latch comes in an entry function in both 2-3/8 and 2-3/4 backsets, and the same body is available in a passage/privacy function as the G1RLP. Those are latches only, though, with no access control of their own.
14) The door only needs to latch, not lock. What is a simpler option than a Lockey M230 keyless combination lock?
The M230 is a code-operated lock with automatic deadlocking on close, which is more than a passage opening needs. For a door that only has to latch or hold privacy, the Deltana G1RLP238 is a Grade 1 regular latch with a passage/privacy function in a 2-3/8 inch backset, and the Deltana G1RLP275 is the same passage/privacy latch in a 2-3/4 inch backset. Neither carries access control; they latch the door and, on the privacy side, hold it closed without a user code to program.
15) I have a Dexter C1000 lockset on the door. Do I order the Dexter deadlatch or the Lockey M230?
Order by what you are replacing. The Dexter Grade 1 Deadlatch for C1000 Series is a Grade 2 latch made to drop into an existing Dexter C1000 lockset, so it keeps the lockset and knob you already have. The Lockey M230 replaces the whole device with a keyless combination lock, covering a standard 2-1/8 inch hole and taking a 1 inch edge bore, and it suits doors 1-1/8 inch to 2 inch thick as standard. If the C1000 trim is staying and only the latch failed, the Dexter part is the direct replacement; if you are converting the opening to code entry, the M230 is the change.
16) Which of these latches has an adjustable backset like the Lockey M230?
The M230 uses an adjustable backset latch so it can be set to the door prep in front of you. Among the comparable latches, the Schlage 16-228 for the S200 and CS210 Series is adjustable 2-3/8 or 2-3/4 inch with a 1-1/8 inch x 2-1/4 inch square corner face, the Schlage 16-480 deadlatch for the S200 Series is adjustable 2-3/8 or 2-3/4 inch with a 1 inch x 2-1/4 inch square corner face, and the Schlage 12-289 deadbolt latch for the B500 Series is adjustable 2-3/8 or 2-3/4 inch. The Deltana G1RLE238 and G1RLE275 are fixed at 2-3/8 inch and 2-3/4 inch respectively, so those you specify by backset up front.
17) What finishes does the Lockey M230 keyless lock come in?
Ten finishes across the M230: Antique Brass, Bright Brass, Bright Chrome, Jet Black, Marine Grade, Oil-Rubbed Bronze, Satin Brass, Satin Chrome, Satin Nickel and White. Satin Chrome and Satin Nickel are the usual matches for existing commercial 626 and 619 hardware, Oil-Rubbed Bronze and Antique Brass for residential and hospitality trim, and Marine Grade where salt exposure is the issue.
18) Is the Lockey M230 rated for commercial traffic, or is it a residential lock?
Commercial. Lockey builds the M230 for commercial duty with a zinc-plated steel body and Teflon coated stainless interior parts, and it is in service in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and municipal buildings. For an MRO buyer standardizing a facility, the single-lock-fits-both-hands design and ten finish choices let you carry one part number across a mixed set of openings.
19) Can I standardize a facility on Lockey M230 locks and Deltana Grade 1 latches on the same doors?
They are different devices and are ordered separately. The Lockey M230 is a complete commercial keyless lock, self-contained with knob operation on the exterior and interior and its own deadlocking spring latch, available in Antique Brass, Bright Brass, Bright Chrome, Jet Black, Marine Grade, Oil-Rubbed Bronze, Satin Brass, Satin Chrome, Satin Nickel and White, in single and double combination. The Deltana G1RLE238, G1RLE275, G1RLP238 and G1RLP275 are Grade 1 regular latches supplied by function and backset for use with a lockset. A common approach is M230 locks on the code-entry openings and Deltana Grade 1 entry or passage/privacy latches behind the keyed and non-locking trim elsewhere in the building.
