A round vs square door handle smart lock decision starts with the exact Lockin Veno model—not the shape you prefer. The current Lockin US storefront pairs the round entry handle with Veno and Veno Pro, while the square entry handle listing names Veno Plus and Veno Go. After matching the model, check the handle's door-thickness range, backset, handing, spacing, and the exact option in your cart.
There is one detail for Veno Go shoppers to note: the current square-handle page title and metadata name Veno Go, and Veno Go's with Door Lever option maps to that square-handle accessory. The feature copy on the accessory page, however, names only Veno Plus. Check the live option and cart line before ordering.
Round vs square door handle smart lock: the quick Veno map
Use this round vs square door handle smart lock table before comparing finishes or bundle choices.
| Your Lockin model | Start with this entry handle | What to verify |
|---|---|---|
| Veno | Round entry handle for Veno and Veno Pro | Exact model, lower-handle preparation, door thickness, backset, spacing, and selected offer |
| Veno Pro | Round entry handle for Veno and Veno Pro | Exact model, lower-handle preparation, door thickness, backset, spacing, and selected offer |
| Veno Plus | Square entry handle for Veno Plus and Veno Go | Exact model, lower-handle preparation, door thickness, backset, spacing, and selected offer |
| Veno Go | Square entry handle for Veno Plus and Veno Go | Confirm the live option and cart line; the listing metadata names Veno Go while the feature copy currently names only Veno Plus |
This mapping is specific to these four Veno models and the two current Lockin accessory listings. It should not be extended automatically to Veno Solar Palm, Veno Solar Face, or another Lockin lock. Check the exact product option for those models.
Why the shape is more than a style choice
In these Lockin listings, “round” and “square” describe the visible trim, or rose, behind the lower lever. Both versions use a black lever, but their model pairings and supported door-thickness ranges are not identical.
That makes this round vs square door handle smart lock question a compatibility decision before it becomes a design decision. A handle can look right beside the lock and still be the wrong accessory record or fall outside its stated fit range.
Also keep three different door parts separate:
- The entry-handle rose is the round or square trim behind the lower lever.
- The lower handle bore and latch are the door preparation used by that lever.
- The deadbolt latch faceplate is part of the smart-deadbolt preparation. Lockin's Veno FAQ separately refers to a rectangular latch-faceplate cutout and says round faceplate cutouts are not compatible with the described Video Veno installation.
Choosing a round entry-handle rose does not mean choosing a round deadbolt latch faceplate. They are different parts of the door.
Is the Veno entry handle required?
Not on every door. A Veno smart lock controls the deadbolt, while the entry handle is a separate lower lever for a door prepared for two pieces of hardware. The current model pages list a base lock option separately from the with Door Lever option.
You may not need a new Veno entry handle when your existing lower knob or lever can remain, operates smoothly, fits the door, and leaves enough room for the exact smart-lock installation. You may want the matching Lockin handle when you are replacing that lower hardware or selecting an option that explicitly includes a door lever.
Do not treat a product-gallery image as package-inclusion proof. If you want the handle in the same order as the lock, confirm that the selected option and cart line actually say with Door Lever, or add the correct standalone accessory deliberately.
Compare the handle-specific fit ranges
For a useful round vs square door handle smart lock comparison, apply the accessory's own specifications—not a family-wide assumption.
| Handle listing | Named model pairing | Supported door thickness | Supported backset | Left/right handing |
|---|---|---|---|---|
| Round entry handle | Veno and Veno Pro | 1-3/8 to 2-11/64 in (35–55 mm) | 2-3/8 or 2-3/4 in (60 or 70 mm) | Reversible |
| Square entry handle | Veno Plus and Veno Go in the listing title/URL; page feature copy names Veno Plus | 1-3/8 to 1-3/4 in (35–45.5 mm) | 2-3/8 or 2-3/4 in (60 or 70 mm) | Reversible |
“Reversible” means each lever can be configured for a left-hand or right-hand door. It does not mean either handle is universal across Veno models.
The square handle's upper door-thickness limit is narrower than the round handle's. This matters because a smart deadbolt and a lower handle are two separate fit checks. Even if the chosen Veno deadbolt supports the door thickness, the complete setup must also stay inside the accessory handle's stated range.
The backset is measured from the door edge to the center of the handle bore. If you are not sure where to measure, review Lockin's current door-fit and installation requirements before ordering.
Use this five-photo and measurement checklist
A round vs square door handle smart lock choice is easier to review when the whole doorway is visible. Before checkout—or before asking support—take these five photos in good light:
- Exterior, full door: Show the smart-deadbolt location, lower knob or lever, door trim, glass, and any storm or screen door.
- Interior, full door: Show the inside hardware, nearby trim, and anything that could limit the lever or smart-lock assembly.
- Door edge: Open the door and photograph both latch areas, their faceplates, and the strike side of the frame.
- Door thickness: Hold a tape measure across the door slab at the hardware height, without including applied trim.
- Backset and spacing: Photograph the measurement from the door edge to the center of the lower handle bore. Then record the clear space from the smart-lock crossbore center to the nearest edge of the lower handle or its trim. Include any molding, glass, or second-door obstruction in the frame.
Write down this short record beside the photos:
Exact Veno model: ______________________________
Selected product option: _______________________
Handle choice: round / square / keep existing
Door thickness: __________ in / __________ mm
Lower-handle backset: _____ in / __________ mm
Crossbore-center-to-handle/trim edge: __________
Door type or nearby obstruction: ______________
Source pages checked on: _______________________
The checklist records your actual layout without inventing a universal spacing number. Lockin labels this the minimum distance between the handle and crossbore center. Current diagrams show 3 in (75 mm) from the smart-lock crossbore center to the nearest edge of the lower handle or trim for Veno and Veno Pro, while the Veno Go guide shows 2 in (50 mm). Lockin's FAQ gives 3 in (75 mm) for Veno Plus specifically for solar charge panel installation. Use the exact model's current instructions rather than carrying one number across the family.
What to do if the model and measurements disagree
Do not solve a round vs square door handle smart lock mismatch by ordering the other shape and hoping it fits. Pause when any of these is true:
- the handle listing does not name your exact model;
- the door is thicker or thinner than the accessory's stated range;
- the backset is not 2-3/8 or 2-3/4 in (60 or 70 mm);
- the lower hardware is interconnected with the deadbolt, part of a mortise or multipoint system, or uses an unusual preparation;
- the lever, smart lock, trim, glass, or second door could collide; or
- the selected option, cart line, accessory page, and manual do not agree.
Use the Lockin Smart Lock Selector to confirm the lock model. Then compare the door photos and measurements with the current accessory page and exact-model documentation. If anything remains unclear, contact Lockin support before ordering or changing the door.
Frequently asked questions
These answers cover the practical round vs square door handle smart lock questions to resolve before checkout.
Can I use the square handle with Veno Pro?
The current Lockin storefront pairs Veno Pro with the round entry-handle listing. Do not substitute the square handle based on appearance alone. Confirm any different combination with Lockin support before ordering.
Can I use the round handle with Veno Plus or Veno Go?
The current storefront directs Veno Plus and Veno Go shoppers to the square entry-handle listing. Veno Go's with Door Lever option maps to the same square accessory, but confirm the live selected option because the accessory page's descriptive feature copy currently names only Veno Plus.
Are both Lockin entry handles reversible?
Yes. The current round and square accessory pages describe their levers as reversible for left-hand and right-hand doors. Reversible handing does not make the handles interchangeable between lock models.
Is the entry handle included with a Veno smart lock?
Only treat it as included when the exact selected offer and cart line state that a door lever is part of the option. A gallery or bundle image alone is not enough. The two handle products are also available as standalone accessory listings.
Can I keep my existing lower handle?
Possibly. It must operate correctly, suit the existing lower-door preparation, and leave enough space for the exact Veno installation. Check the complete door layout rather than matching finish alone.
Does the 3-inch spacing in the FAQ apply to every setup?
No. The current FAQ labels its 3 in (75 mm) minimum as a condition for solar charge panel installation. Use model- and accessory-specific documentation for other configurations instead of turning it into a universal rule.
Which handle fits Veno Solar Palm or Veno Solar Face?
This four-model map does not assign a universal handle to the Veno Solar models. Review the exact Solar product option and current documentation, then verify the selected offer before checkout.
Match the model, then check the door
The safest way to finish a round vs square door handle smart lock decision is simple: match the handle listing to the exact Veno model, then verify the door and selected offer. Choose the round listing for Veno or Veno Pro. Start with the square listing for Veno Plus or Veno Go, with an extra live-option check for Veno Go. Finally, confirm door thickness, backset, handing, spacing, and cart contents.
