Working with OEM and Store Brands

When the product carries your name, the conversation stops being about price and starts being about control: control of the mark, the code, the packing and the change.

What OEM actually covers

OEM is used loosely. In practice it spans five levels, and it is worth being explicit about which one you are buying:

  1. Mark only — your logo on an existing product
  2. Mark and packaging — logo, plus a card, blister or box carrying your brand
  3. Appearance — colour, finish or plating to your reference
  4. Configuration — keying, coding and locking mechanism variants
  5. Form — a new shape or mechanism, which means a new mold

Most store-brand programmes need levels one to three. Level five is a different decision with a different cost structure.

Start at the cheapest level that solves the problem

Branding decisions escalate in cost as they move from mark to mold. It is worth asking what the mark is for — recognition on a shelf, or differentiation of the mechanism itself.

If the answer is recognition, a laser mark on the body and the key, plus branded packing, does the job on an existing product. If the answer is that the shape is the product, then tooling is justified — and it should be quoted separately, so it never hides inside the unit price and reappears on the second order.

Change control is what protects the brand

The risk in an OEM programme is not the first shipment. It is a later shipment that quietly differs — a substituted internal part, a finish that reads slightly different, a mark placed a few millimetres off.

The defence is an approved sample held by both parties, plus a rule that any change to the product requires a new sample and a written approval before production. Without that rule, a cost reduction somewhere in the chain becomes a customer complaint with your name on it.

Files, artwork and who owns what

OEM orders run on files: your logo, your artwork, sometimes your serial or code data. Three practical points prevent trouble later:

  • Send artwork in a usable format, and confirm the proof before production rather than after the goods arrive.
  • Treat code data as data. A file of serial numbers and unique codes should be checked before production — duplicates, wrong lengths and missing entries are common and cheap to fix beforehand.
  • Agree where the artwork lives. If the supplier holds your artwork, it should be held against your account and used only for your orders.

What we typically see

  • A brand that assumed the mark would appear on the key as well as the body, and did not say so.
  • Tooling paid for inside a unit price, then charged again on the next order.
  • A colour specified by name rather than by a physical reference, producing a batch that is 'blue' but not the blue.
  • A code file with short or duplicated entries, discovered during production instead of before it.

How an OEM programme usually starts

The lowest-risk start is a marked sample: an existing product carrying your mark and, if relevant, your packaging, produced before any volume commitment. It answers the question that matters most — how your brand actually looks on the product — for the cost of a sample.

Confirm it on your own doors

Send a door photo, the cylinder size or the mounting dimensions. We confirm fit with a physical sample before you commit to a quantity.
