How to Safely Duplicate DOM-MCM Keys

Making a key copy may seem simple, but when it comes to DOM-MCM security keys, the process requires special care to keep your property protected. Learn where to duplicate keys and what you need depending on your cylinder type.

Duplicating High-Security DOM Keys

High-security cylinders such as DOM Diamant, ix TwinStar, ix DAS, ix Teco, ix 6SR, ix Twido, and ix Twintec follow strict duplication rules:

• 🔒 Where to copy: only at authorized DOM Technical Centers.

• 📇 What you need: the ownership card that comes with the cylinder and your original key.

• ✅ Why: it prevents unauthorized copies and guarantees full protection of your locking system.

Duplicating MCM Keys

For non-patented MCM cylinders (e.g. SCX+, BPS), the process is more flexible:

• You can request a copy in many locksmith shops and hardware stores.

• However, visiting an authorized DOM-MCM dealer ensures better accuracy and compatibility.

• If your model includes an ownership card, it must also be presented.

Duplicating Old or Discontinued Keys

Many users still have older DOM or MCM keys:

• Some models may be discontinued, making copies more complex.

• In certain cases, the best option is to replace the cylinder with a current security model.

• An authorized locksmith will advise you on the safest solution.
