Omnia D12036AC55.34.26D – Frequently Asked Questions

1) What backset does the Omnia D12036AC deadbolt lever lockset come in, and will it fit my existing door prep?
The D12036AC is offered in both 2-3/8 inch and 2-3/4 inch backsets, which are the two standard bored-door backsets, so it drops onto most existing residential preps. The deadbolt and lever bores are fixed at 5-1/2 inches center to center, so measure that spacing on your door before picking a backset.
2) Will an Omnia D12036AC sideplate lockset cover the holes left by a separate deadbolt and lever?
That depends on your hole spacing. The sideplate is a single plate 10-9/16 inches long by 2-3/8 inches wide with the deadbolt and lever bores set 5-1/2 inches apart. If your existing deadbolt and knob bores are spaced at 5-1/2 inches, the plate lands over both. If they are spaced further apart, which is common when the two were installed as separate pieces, the plate will not reach and you need a different arrangement.
3) Does the Omnia D12036AC need a key on the inside too?
Yes. It is a double cylinder unit, keyed from both the exterior and interior. That gives you control over egress next to glass, but it also means no one leaves without a key in hand, which many local codes prohibit on a required exit door in a dwelling. If you want thumbturn release inside, order the single cylinder version of the same lockset instead.
4) What is the difference between the Omnia D12036AC and the Emtek 5302 single point lockset with the Hanover lever?
The Omnia D12036AC is a double cylinder unit, meaning it is keyed from both the inside and the outside. The Emtek 5302 with the Hanover lever is a single cylinder entry function, so the interior side operates without a key. Choose the D12036AC where you want key control on both faces of the door, and the Emtek Hanover version where an occupant needs to exit without hunting for a key.
5) I need a keyed entry lever but a double keyed lock will not pass egress code in my building - what should I use instead of the Omnia D12036AC?
Where a thumbturn interior is required for egress, look at the Emtek 5302 single point lockset with the Hanover lever, which is a single cylinder entry function with a lever trim. The Omnia D12036AC is double cylinder and takes a key on both sides, so it is generally reserved for openings without a code-driven keyless egress requirement, such as doors with adjacent glass where local authorities permit it.
6) Is the Emtek 5302 Modern Rectangular brass tubular lockset a drop-in substitute for the Omnia D12036AC?
They are not the same type of assembly. The Omnia D12036AC is a sideplate lockset with a 5-1/2 inch center to center between the deadbolt and lever, an overall plate length of 10-9/16 inches and a 2-3/8 inch plate width, so the door face carries a long plate. The Emtek 5302 Modern Rectangular is a brass tubular key-in-knob/lever design on a separate rectangular rosette. Swapping one for the other means new door prep, not just new hardware.
7) How much does the Omnia D12036AC lockset stick out from the door face?
Projection is 2-1/2 inches. Worth checking against a storm door, a tight door swing into a return wall, or a cabinet or trim piece near the jamb, since a lever plus deadbolt assembly at that projection needs clearance the original knob may not have required.
8) Is the Omnia D12036AC rated for a commercial opening or a school corridor?
It is a residential lockset. Omnia lists it for entry doors, private offices, multi-family units, and executive suite doors. For a high-traffic institutional corridor you want a commercial bored or mortise lock rather than a residential brass sideplate unit.
9) How is the Omnia D12036AC different from an Emtek tubular entry lockset?
Both are brass entry hardware, but the configurations differ. The D12036AC is a sideplate unit combining a deadbolt and a lever on one plate, keyed both sides. The Emtek 5302 Modern Rectangular is a brass tubular key-in-knob/lever single point lockset, and the Emtek versions with the Hanover or Helios lever are single cylinder entry function, meaning the inside releases without a key. Choose the Omnia when you want the deadbolt and lever unified on one plate; choose the Emtek single point when you want a simpler tubular prep and keyless egress.
10) I want lever handles but no key on the inside. What should I get instead of the D12036AC?
Skip the double cylinder D12036AC. For lever operation with keyless egress inside, look at an Emtek Modern Rectangular single point lockset with the Hanover lever, which is single cylinder entry function, or the same platform with the Helios lever.
11) My doors are prepped with a 2-3/8 inch backset - will the Omnia D12036AC work, or do I need a different lockset?
The Omnia D12036AC is offered in both 2-3/8 inch and 2-3/4 inch backsets, each with the 5-1/2 inch center to center spacing, so an existing 2-3/8 inch prep is covered without moving to another product. Finish choices run the same across both backsets: polished brass, oil-rubbed bronze, satin nickel plated, polished chrome plated and satin chrome plated.
12) If I want a knob instead of a lever, what is the closest alternative to the Omnia D12036AC?
The Omnia D12036AC uses lever trim. For a knob, the Emtek 5302 Modern Rectangular single point lockset with round knobs covers the same entry role with a round knob instead. Note the Emtek round knob version is a single cylinder entry function rather than double cylinder, so the interior side will not be keyed.
13) What is the Omnia D12036AC actually made of?
Solid brass throughout, plated or finished to the five available options. Brass holds up against corrosion, which is why it shows up on exterior entry doors where a plated steel escutcheon would eventually pit.
