Smart Locks for Door Manufacturers

For a door manufacturer the lock is a component, not a product. It has to fit a hole that is already jigged, and it has to arrive in a way the line can use.

Who This Page Is For

Two things worth knowing before the first order, whichever product you end up buying.

The lock is a component, not a finished good

It goes into something you already build, so the specification is driven by your jig and your assembly sequence, not by what sells on a shelf.

Three dimensions decide whether it assembles

Bore position, backset and door thickness. Get those three right and the lock becomes a line item rather than a project.

Five Questions Door manufacturers Ask

The five that come up most often in this buyer group, answered with the conditions attached.

Buyer questions

Can you match our existing door prep?

Send the drawing or the jig dimensions. We confirm the bore position, backset and thickness in writing, then sample before the production run.

Where does mismatching usually go wrong?

Almost always the bore or the backset, and almost always because the lock was chosen from a photograph rather than from the drawing.

Can the lock be keyed as it leaves the factory?

Yes. Keyed-alike and master-key plans can be set at production, which avoids a re-keying step on your line.

Can you supply bulk-packed for the line?

Yes. Bulk or line-feed packing is arranged instead of retail packaging, with the carton marking your line needs.

Can delivery follow our production schedule?

Where your line consumes in a rhythm, we ship to that rhythm rather than sending one large delivery that has to be stored.

Four Mistakes We See Most

Each of these has cost somebody a shipment. All four are avoidable at quote stage.

Mounting holes that do not match the jig

This is the one error that stops a line. It is prevented by working from the drawing and sampling, not by reading a specification sheet.

The key plan arriving too late

Keying is done at production. A key plan that arrives afterwards means re-keying or a second batch.

Retail packaging on a production line

A line does not need shelf-ready boxes. Bulk packing is cheaper and faster to handle.

Assuming a document pack is included

Tell us which certificates your customers ask for, and we will confirm what we hold rather than assuming.

How We Work With You

Four stages, and what we need from you at each one.

  1. Work from the drawing, not a product photo

    We confirm bore, backset and thickness against your drawing before anything is built.

  2. Set keying at production

    Keyed-alike and master-key plans are applied during assembly.

  3. Pack for the line

    Bulk or line-feed packing with carton marking that suits your handling.

  4. Repeat against the frozen file

    The confirmed dimensions stay on file so the next batch assembles the same way.
