Short answer: a smart lock can work behind some storm or screen doors, but only when the exact lock, both doors, and the full swing path have been checked together. For Lockin specifically, the current Veno Pro and Veno Plus guidance says these video models are not compatible with storm doors because the second door may block the integrated camera. Do not plan a standard Veno Pro or Veno Plus installation behind a storm door.
Veno and Veno Go do not have an integrated camera, so they avoid that specific camera conflict. That does not make either model automatically compatible. You still need to measure the closed gap, moving clearance, handles, door preparation, and any planned solar-panel location, then confirm the exact model guidance before ordering.
For renters, add one step before every measurement: get written approval from the landlord or property manager. Photograph the original hardware, keep every removed part and key, and do not drill or permanently alter either door unless the approval expressly allows it.
The 60-second decision before you measure
Use this quick screen before spending move-in day with a screwdriver:
- Keeping a storm door and considering Veno Pro or Veno Plus? Stop. Current Lockin product and quick-start guidance lists the storm door as incompatible because it may block the camera.
- Keeping the storm door and considering Veno or Veno Go? Measure first. Their lack of an integrated camera removes one possible obstruction, not every fit problem.
- Renting? Get written permission. Confirm whether you may replace the deadbolt, whether drilling is allowed, and whether the original hardware must be restored at move-out.
- Any contact, blocked sightline, uncertain light, or nonstandard door prep? Do not guess. Send Lockin Support the worksheet and photos described below before purchase or installation.
This is the practical dividing line: a camera model has both physical-clearance and visibility requirements. A non-camera model still has physical-clearance and door-prep requirements.
How to measure a smart lock with a storm door
Measure with both doors closed, then again while the storm door moves through its entire arc. A single gap measurement is not enough: handles, closer arms, trim, glass frames, or a warped panel can become the closest point during movement.
Use a rigid ruler or tape measure. Place it in the photo so Support can read the scale. Write measurements in both inches and millimeters if practical.
1. Photograph the complete doorway
Take one straight-on photo from outside with the storm door closed, one with it fully open, and one from inside. Include the hinges, closer arm, latch side, handles, and the entire deadbolt area. These overview images show door handing and features that close-up measurements can miss.
2. Measure the closed gap at lock height
Close both doors gently. At the deadbolt height, measure from the face of the entry door to the nearest interior surface of the storm door. Repeat at the top, middle, and bottom of the proposed exterior lock body. A decorative panel, glass retainer, or handle may sit closer than the main door panel.
Do not treat this empty-door gap as your final pass/fail result. The proposed smart-lock body projects away from the entry door, so its full installed envelope must fit inside the available space without touching the storm door.
3. Trace the moving swing clearance
Open and close the storm door slowly through its full travel. Watch the panel, handle, latch, closer hardware, frame, and any flex in the door. Measure the smallest distance to the entry door around the future smart-lock location.
If any part of the storm door would touch the lock, stop. Repeated contact can interfere with normal operation and may damage the door or hardware.
4. Check both handles, not just the deadbolt
Measure the horizontal and vertical distance between the storm-door handle or latch and the center of the entry-door deadbolt. Also measure the clearance below the deadbolt for the entry-door handle. Compare those measurements with the current installation drawing for the exact Lockin model.
This is especially important when the two handles sit at similar heights. They can collide even when the main lock bodies clear each other.
5. Check the camera sightline and usable light path
For a video smart lock, clearance is not only about avoiding contact. A storm-door frame, panel, glass, screen, or reflection can obstruct or degrade the view. Lockin's current Veno Pro and Veno Plus guidance resolves this question directly: those models are listed as incompatible with storm doors because the camera may be blocked.
If you are also considering the optional external solar panel offered for Veno Pro or Veno Plus, check the proposed panel location for the same storm-door obstruction, porch depth, overhang, and shade. Solar output depends on placement and available light. An external panel is not a workaround for the Pro/Plus storm-door camera restriction.
6. Record the existing deadbolt preparation
Remove nothing unless you have permission. With the door open, photograph the deadbolt from both faces and the door edge. Record:
- entry-door material and thickness;
- cross-bore diameter, the large hole through the door;
- backset, from the door edge to the center of that hole;
- edge-bore diameter and latch faceplate shape;
- center-to-center distance between the deadbolt and lower handle;
- whether the existing hardware is a single-cylinder deadbolt or another lock type; and
- left- or right-hand orientation and the direction each door swings.
Lockin's current guides use model-specific limits for these dimensions, and the limits are not identical across every Veno model or guide revision. Compare your numbers with the current quick-start guides for the exact model. If the storefront specifications and the downloaded guide appear different, send both your measurements and the guide date to Support rather than choosing the more convenient number.
Storm-door clearance worksheet
Fill this out before choosing a model. Use “not applicable” instead of leaving a check blank.
| Fit check | Where and how to measure | Your measurement or photo | Pass rule |
|---|---|---|---|
| Written approval | Lease, landlord, property manager, or building office | Approval date/file: ______ | Replacement and any drilling are expressly allowed |
| Door overview | Both doors closed, open, inside, and outside | Photos: ______ | Hinges, closer, handles, and lock area are visible |
| Closed gap | Entry-door face to nearest storm-door surface at top/middle/bottom of lock area | Top: ___ / Middle: ___ / Bottom: ___ | Full installed lock envelope fits without contact |
| Moving clearance | Smallest gap through the entire storm-door swing | Minimum: ______ | No panel, handle, latch, closer, or trim can strike the lock |
| Handle spacing | Storm-door hardware to deadbolt center; deadbolt center to lower entry handle | Horizontal: ___ / Vertical: ___ | Meets the exact model drawing and both handles move freely |
| Camera path | Straight-ahead and angled path through the outer door | Photos: ______ | Not a pass for Veno Pro/Plus with a storm door under current guidance |
| Solar/light path | Proposed external-panel position, including glass, mesh, shade, and overhang | Photos/time checked: ______ | Placement and model compatibility confirmed; no assumed output |
| Door thickness | Edge of the open entry door | ______ | Within the exact model's current published range |
| Cross bore | Diameter of the large deadbolt hole | ______ | Matches the exact model's current guide |
| Backset | Door edge to cross-bore center | ______ | Matches the exact model's current guide |
| Edge bore/faceplate | Latch hole diameter and faceplate shape | ______ | Matches the exact model's current guide |
| Lower-handle clearance | Deadbolt center to lower-handle center/trim | ______ | Meets the exact model's minimum and clears all trim |
Fit rule: do not mark a row “pass” because the number looks generous. Compare it with the current instructions for the exact model, and include the full installed lock body—not just the existing deadbolt—in the clearance check.
Which Veno path matches a storm-door entry?
| Model path | Integrated camera | Current storm-door evidence | Move-in decision |
|---|---|---|---|
| Veno Pro | Yes—2K/180° | Official page and guide say incompatible because a storm door may block the camera | Do not plan the standard installation behind a storm door |
| Veno Plus | Yes—2K/180° | Official page and guide say incompatible because a storm door may block the camera | Do not plan the standard installation behind a storm door |
| Veno | No | No verified storm-door fit statement in the current page/guide reviewed for this article | Measure every physical condition and confirm before ordering |
| Veno Go | No | No verified storm-door fit statement in the current page/guide reviewed for this article | Measure every physical condition and confirm before ordering |
The non-camera rows are possible comparison paths, not compatibility approvals. A second exterior door can still collide with the exterior lock body or handle, and the entry door itself must still meet the exact model's preparation requirements.
If you need palm-vein entry and your measurements support a non-camera path, use the Smart Lock Selector to compare current features. If an integrated door camera is essential, the current Pro/Plus storm-door warning means this doorway needs a different plan before you choose the lock.
A support-ready photo and measurement packet
When fit is uncertain, “Will this work?” is hard to answer from a single front photo. Send a compact packet:
- The model you are considering: Veno Pro, Veno Plus, Veno, or Veno Go.
- A straight-on photo from outside with the storm door closed.
- A straight-on photo with the storm door fully open.
- A side photo at deadbolt height showing a ruler across the closed gap.
- A short video of the full storm-door swing, including the closer arm and both handles.
- Close-ups of the entry-door edge, latch faceplate, existing deadbolt, and lower handle.
- Door thickness, cross bore, backset, edge bore, and handle-spacing measurements.
- The exact quick-start guide or product-page link you used.
- For a planned external solar panel, photos of the proposed placement at the times it is normally shaded and lit.
You can start with Lockin's FAQ and then contact support@lockin.com with the packet. Keep the written reply with your lease approval and move-in records.
Renter-friendly installation and move-out planning
A good fit check protects more than the return window. It helps you avoid an unapproved alteration on a busy move-in day.
- Keep the original hardware together. Label the deadbolt, strike, screws, keys, and any spacers in one bag so you can restore the door at move-out.
- Do not enlarge holes “just a little” without approval. A different cross bore, backset, faceplate, or strike preparation can turn a reversible swap into a permanent change.
- Remember the outer door. If the storm door has its own keyed latch, smart access on the entry door does not unlock that outer latch. Agree on how roommates will use it.
- Plan household access. Create individual or temporary codes where the selected model supports them, remove old access at roommate turnover, and avoid sharing one household PIN broadly.
- Keep backup entry available. Know where the mechanical key is stored, charge the removable battery before installation, and keep an appropriate USB-C power source available for emergency power according to the model guide.
- Test before calling the job finished. Confirm that the latch moves smoothly, the hardware is rigid, the storm door completes its full swing without contact, access methods work, and auto-lock behaves as expected.

Frequently asked questions
Can you use a smart lock with a storm door?
Sometimes, but the exact lock and doorway must be checked together. A storm door can strike a lock body or handle, and it can block a camera or light path. Current Lockin guidance specifically lists Veno Pro and Veno Plus as incompatible with storm doors because the camera may be blocked. Veno and Veno Go still require measurements and confirmation; no automatic storm-door compatibility is implied.
Will a screen door block a video smart lock camera?
It can. The frame, mesh, glass, reflections, or door position may obstruct the view. For Veno Pro and Veno Plus, follow Lockin's explicit current incompatibility statement instead of trying to judge the image quality after installation.
Does choosing a non-camera smart lock guarantee clearance?
No. It removes the integrated-camera sightline from the fit check, but the exterior lock body, storm-door panel, handles, trim, closer, swing arc, and entry-door preparation still have to work together.
What should a renter ask a landlord before installing a smart lock?
Ask in writing whether deadbolt replacement is permitted, whether drilling or hole enlargement is allowed, whether management needs a key or approved access method, and whether the original hardware must be restored. Also check building, fire, and egress rules that apply to the unit.
Can a storm door reduce solar charging?
An obstruction, overhang, deep shade, glass, or screen can change the usable light at a proposed external solar-panel location. Check the actual placement and current accessory guidance. Solar assistance is condition-dependent and does not change the Veno Pro/Plus storm-door camera warning.
What measurements should I send to Lockin Support?
Send the closed gap at the top, middle, and bottom of the proposed lock area; minimum moving clearance through the storm-door swing; handle spacing; entry-door thickness; cross bore; backset; edge bore and faceplate shape; lower-handle spacing; and clear photos with a ruler visible. Name the exact model and include the current guide you used.
Measure first, then compare the exact model
A smart lock with a storm door is a doorway-fit decision, not a category-wide yes or no. Record the worksheet, keep the photos, and compare the exact current Veno Pro, Veno Plus, Veno, or Veno Go guidance. If anything is ambiguous, send Support the packet before you order or alter the door.
