Customization
Custom locks built to your specification
From a logo on a key to a new mechanism — with the drawings we need, the sample we check, and the time each change actually adds.
Six types of customization
Find the row that describes what you are asking for — it decides the minimum order, the tooling and the lead time.
| Type | What it covers | Minimum order |
|---|---|---|
| Minor modification | Colour, finish, key quantity, screw specification, small dimensional tweaks inside the existing tooling | Standard MOQ from 500 pcs |
| OEM / private label | Your brand on the lock body, the key and the packaging, to your artwork | Standard MOQ from 500 pcs |
| Logo and serial marking | Laser logo, unit-level serial numbers applied from your data file | Standard MOQ from 500 pcs |
| Material or finish change | SS201 to SS304, satin nickel to matte black, brushed to mirror, plating changes | Confirmed per model |
| Drawing-based build | Made to your 2D/3D drawing, or measured from a physical sample you send | Confirmed after feasibility review |
| ODM development | We design the housing or mechanism with you, then build the tooling | Confirmed after design review |
If your request moves a core mechanism dimension, it is not a minor change — it is a new mold. We will say so at the feasibility stage rather than in the invoice.
How a customization order runs
Timings below are for a full customization that needs new tooling. A minor modification or a private-label run skips the tooling stage.
Requirement
3–5 days. You tell us the model, the change and the quantity. Deliverable: a written requirement summary you can correct.
Design and feasibility
7–14 days. We confirm what is possible, what it costs and the minimum run. Deliverable: drawing or specification sheet.
Quotation confirmed
3–5 days. Tooling and unit price quoted separately, so you can see which part is one-off.
Tooling
15–25 days — only for a new mold or a structural change. Ownership and maintenance terms are agreed in writing before cutting starts.
Sample
7–10 days. A physical sample off the tooling, sent to you for fit and finish checks on your own door.
Sample approval
3–7 days. You confirm or send marked-up changes. Nothing goes into production unapproved.
Batch production
Around 30 days after the specification and artwork are confirmed, with inspection records and pre-shipment photos.
Serial numbers
If your order needs a unique number on each unit, send us the file. The numbers are laser-marked during production, and your file is checked for errors before we start — including numbers that are too short, duplicated or out of sequence.
Tooling
New mold costs are quoted separately and transparently, so your unit price reflects production, not tooling you did not agree to.
Tooling ownership and maintenance terms are agreed in writing before development starts.
Drawings and files we need
Send the format you already have. Where something is missing, we ask before quoting rather than after the tooling is cut.
| File | Format | What it must contain |
|---|---|---|
| 2D engineering drawing | DWG, DXF, PDF | Dimensions with tolerances, material and surface finish |
| 3D model | STEP, IGES, STL | A complete solid model with the assembly relationships |
| Assembly drawing | PDF, DWG | How the parts fit together and the fastener specification |
| Bill of materials | Excel, PDF | Part list, quantities and specification per line |
No drawing? Send a physical sample instead. We measure it, send a dimensional drawing back for your confirmation, and build to the drawing you approved — not to the sample as received.
Samples: what to send us
Sample-based development is the fastest route when the part already exists — but only if the sample can be measured and taken apart.
- 2–3 pieces
- One to disassemble and measure, one for function and destructive testing, one to keep as the reference against the drawing.
- A finished, working product
- A bench sample or a raw casting tells us the shape but not the mechanism, the tolerances or the finish you actually expect.
- Written notes on material, colour and function
- Sample colour is judged by eye and light. Written references — grade, RAL or Pantone, function requirements — are what we build to.
- Packaging sample or photo, if packaging matters
- Box dimensions, print position and the retail card layout are easier to match from one physical example than from a description.
- What you get back
- A sample from the production line rather than a bench build, plus the drawing or inspection record that goes with it.
Send 2–3 units by courier and tell us the model or the door it fits. We confirm receipt and the development route within 4 business hours.
Minor modifications: what they add in cost and time
Small changes are rarely free and rarely instant. This is what each one typically adds — confirmed per order, not assumed.
| Change | Examples | Added cost | Added lead time |
|---|---|---|---|
| Colour or finish | Satin nickel to matte black, brushed to mirror | Low | +0–3 days |
| Small dimensional change | Handle length or body detail inside the current tooling | Low–medium | +3–5 days |
| Material substitution | SS201 to SS304 | Medium | +0–3 days |
| Packaging | Printed box, blister card, retail gift box | Low–medium | +3–7 days |
| Logo application | Laser engraving, silk screen, stamped mark | Low | +1–3 days |
| Accessory change | Key quantity, screw or fixing specification | Low | +0–2 days |
Lead times run from a confirmed specification. Where a change affects tooling, the modification becomes a development project and is quoted as one.
OEM and ODM — which one do you need?
The difference is who brings the design. It changes the tooling, the minimum run and who owns what afterwards.
OEM — you bring the design
You supply the drawing or the sample and the brand artwork. We manufacture to your specification, mark it with your logo and ship it under your label.
Suits projects where your brand already owns the product definition.
ODM — we develop it with you
You describe the requirement; our five-person engineering team produces the design, the drawings and the tooling. You approve the design before anything is cut.
Suits projects where the problem is known but the mechanism is not.
| Question | OEM | ODM |
|---|---|---|
| Where the design comes from | You | Our engineering team, with your approval |
| Drawings and tooling | Built to your files; tooling terms agreed in writing | Developed here; ownership agreed before development starts |
| Minimum order | From 500 pcs for private label; higher for structural change | Confirmed after the design review |
| Typical added time | +1–3 days for marking, +3–7 days for packaging | Design and tooling as listed above, then sampling |
Branding in three places
The product, the key and the box the tenant opens.
On the lock body
Laser-marked logo and unit serial number, permanent and legible.
On the key
Logo on the key head, and key stamping where the key system allows.
On the packaging
Printed box, blister card or paper card to your artwork.
Customization questions
What is the minimum order for a custom lock?
Light customization — logo, colour, packaging — normally runs at the standard MOQ from 500 pcs for the mechanical families. Structural changes and new molds depend on the tooling and are quoted separately, with the minimum run confirmed before we start.
Can you work from our drawing?
Yes. Send a drawing, a 3D file or a physical sample. We review feasibility, come back with the tooling cost and the minimum run, and issue a proof before anything is cut.
Who checks our serial number file?
We do, before production. If your file contains a number that is too short, duplicated or missing, we tell you before we start rather than shipping locks that cannot be marked correctly.
Do you keep our specification for re-orders?
Yes. Dimensions, finish, artwork and keying are stored against your specification, so a re-order two years later matches what you already installed.
Can our logo go on the packaging as well as the product?
Yes, and packaging artwork is the most common request. Send the artwork file and we will confirm the printable areas, the colour reference and the printing quantity that applies before production.
What cannot be changed on a standard model?
Anything that moves the core dimensions of the mechanism, because it affects the tooling and the existing test coverage. Where a request falls into that group we say so before development starts and quote a new-mold route if you want to pursue it.
