Door Compatibility Guides

Smart Lock Compatibility And Measurement Guides

Use these guides to prepare door type, finished thickness, available panel space, mortise, backset, opening direction, existing cutouts and photo evidence before choosing a smart lock model or requesting a compatibility review.

Compatibility review helps narrow the model and lock-body direction. Final drilling, installation and setup must still follow the confirmed model drawing, template or manual.

Smart lock panels, mortise, measuring tools and door details prepared for compatibility review. — Pre-Purchase Compatibility **Measure the door before choosing the final lock and mortise.**
A useful review connects the door structure, current lock body, available space and required modification to a specific model direction.

Four Compatibility Signals

Pre-purchase compatibility review should identify the door construction, finished thickness, available panel space, mortise or lock body, backset, handing, frame clearance, existing cutouts and photo evidence before a final smart lock model or drilling template is approved. Final compatibility depends on the selected model, mortise and door condition.

01 Door Geometry Measure the finished door, not an assumed nominal size.

Door thickness, available panel or stile width, edge depth and frame clearance affect panel, screw, spindle and mortise options.

02 Mortise and Backset Identify the lock body behind the visible panels.

Faceplate, latch, bolt, backset, center distance and lock-body depth can decide whether an existing door can accept the selected route.

03 Opening and Frame Record movement, handing and strike relationships.

Opening direction, active side, frame, keeper, strike and nearby obstructions affect handle, latch and installation planning.

04 Existing Cutouts Treat old holes as a modification risk, not a minor detail.

Existing holes, edge slots and panel coverage should be recorded with dimensions and photos before a replacement model is approved.

Start by Door Task

Choose the Guide That Matches the Door Condition

Start with the physical question blocking model selection. New doors, replacement doors, narrow frames and unknown mortises need different evidence before a supplier can review compatibility.

Compatibility Review

What information is needed before choosing a smart lock?

Prepare door type, thickness, panel space, opening direction, frame, mortise, old holes and photo evidence before model selection.

Open guide Mortise and Backset

Which lock-body details affect compatibility?

Review faceplate, latch, bolt, dimensions, backset, spindle or handle centers and the relationship between the mortise and panels.

Open guide Door Thickness

Where should the finished door thickness be measured?

Measure the actual finished slab and relevant layers rather than relying on a nominal door description or an unconfirmed drawing.

Read guide Existing Lock Body

How can we identify the current mortise?

Record faceplate, latch, bolt, dimensions, centers, backset and any markings before deciding whether the lock body can remain or must change.

Read guide Retrofit Risk

Can the new lock cover or reuse the existing holes?

Capture old panel outlines, through-holes, edge slots, centers and edge distances to identify repair, redrilling or alternative-model risk.

Read guide Door Photos

Which photos should be sent to the supplier?

Prepare front, rear, edge, frame, mortise, current lock and dimension-reference photos so the review is based on the real door.

Door Measurement Evidence

Keep the measurement question separate from the installation file.

Photos and measurements support preliminary review but do not replace the confirmed model drawing or installation file. The focused guides explain how to collect each field so SivoLock can review the next product direction responsibly.

Measure at the lock area, not only from a door catalog description.
Show the frame, edge, existing lock body and usable panel space.
Keep confidential project information unreadable where needed.

Pre-Purchase Compatibility Workflow

Move From Door Evidence to a Model-Review Decision

Compatibility review should move in a controlled sequence. Begin with the physical door and existing hardware, then compare those inputs with a specific product and mortise direction before any final drilling or installation decision.

01 Door ConditionStart with the real door and project state.

Record whether the door is new, already produced, installed, replacing an existing lock or part of a repeat project.

Door material
Current lock status
Drawing or site measurement
Single or batch project

Output: Review route and evidence source

02 Door GeometryMeasure thickness, panel space and clearances.

Capture finished door thickness, front and rear panel area, stile width, edge depth and nearby obstructions.

Finished thickness
Panel width
Stile width
Frame clearance

Output: Physical space envelope

03 Lock BodyRecord the mortise before assuming it can be reused.

Measure or document faceplate, body dimensions, latch and bolt positions, backset and relevant centers.

Mortise type
Faceplate
Backset
Spindle center

Output: Mortise compatibility profile

04 Opening and FrameDefine the movement and locking relationship.

Use a consistent viewpoint to record movement, hinge side, active panel, frame condition and keeper position.

Inward or outward
Hinge side
Strike or keeper
Bolt clearance

Output: Opening and engagement context

05 Evidence PackageShow what dimensions alone cannot explain.

Provide front, rear, edge, frame and mortise photos together with existing-hole measurements or door-factory drawings.

Front and rear
Door edge
Old holes
Drawing revision

Output: Reviewable evidence package

06 Model ReviewMatch the evidence to a model and mortise configuration.

Compare door data with the selected product family, panel dimensions, mortise, spindle, screw set and model-specific constraints.

Product family
Exact model
Mortise option
Required modification

Output: Compatibility review status

Compatibility Review Status

Use a Review Status Instead of a Simple Yes or No

Compatibility review should end with a documented status that still depends on the selected model, mortise direction and confirmed drawing or sample check.

Status A

Suitable for Detailed Model Review

The available door data appears compatible with a defined model and mortise direction, subject to the final drawing and sample confirmation.

Status B

Possible With Modification

The direction may work, but the existing mortise, cutouts, frame or door preparation requires a documented modification plan.

Status C

More Information Required

The current photos or measurements are not sufficient to make a responsible recommendation.

Status D

Alternative Direction Required

The current model or mortise direction conflicts with the available geometry, existing hardware or door construction, so another product or door-preparation route should be reviewed.

Retrofit and Mortise Review

Existing cutouts may change the model direction.

Existing cutouts may require repair, redrilling, another mortise or a different model direction. Record old panel outlines, edge slots, centers and frame relationships before assuming a new lock can reuse the same preparation.

Do not approve final drilling from a generic category description.
Compare cutouts and panel coverage against the selected model.
Use Installation Support only after the model and mortise are confirmed.

Door Compatibility FAQ

Questions Before Model Selection and Installation

These answers separate preliminary compatibility review from final model drawings and installation support.

What should be checked before choosing a smart lock for a door?

Start with the door type and construction, finished thickness, available panel or stile space, mortise or lock-body details, backset, opening direction, frame or keeper condition, existing cutouts and clear photos. These inputs narrow the product direction, but final compatibility still depends on the selected model and its applicable drawing or specification.

Can door photos alone confirm smart lock compatibility?

Photos are useful for showing the door, frame, current lock, mortise and old holes, but they usually need to be combined with measurements or drawings. A photo-only review should not be treated as final approval for drilling, ordering or installation.

What is the difference between compatibility guidance and installation support?

Compatibility guidance is used before model selection to prepare and evaluate door information. Installation Support begins after the model, mortise and configuration are confirmed and provides the applicable drawing, cutout, assembly, setup and troubleshooting route.

Can a smart lock replace an existing mechanical or electronic lock without modifying the door?

Sometimes, but replacement depends on the current mortise, backset, handle or spindle centers, panel coverage, old holes, door edge slot and frame relationship. Some doors require redrilling, repair, a different mortise or a different product direction.

Does the correct door thickness guarantee that a smart lock will fit?

No. Door thickness is only one input. Panel width, mortise dimensions, backset, centers, opening direction, frame clearance, existing holes and the selected model configuration can also affect compatibility.

Which document should control the final drilling dimensions?

Use the drawing, cutout template or installation manual confirmed for the selected model, mortise and order configuration. Generic category diagrams, website images and preliminary compatibility notes should not be used as final drilling instructions.

Prepare the Door for Review

Send the measurements, photos and existing lock details before choosing the final model.

Share the door type, finished thickness, available panel space, mortise or lock-body details, backset, opening direction, frame condition, current cutouts and target application. SivoLock can then identify the next product or technical review route for that configuration.
