Types of Keys We Duplicate

Moving into a new place and want extra copies? Giving a spare to a neighbour or family member? From our experience, most people only think about key duplication when they actually need it — and then it's urgent. We carry professional cutting equipment for every type of key used across Brussels and Brabant, so it's usually done in minutes.

Flat keys and standard keys

Flat keys remain the most common type found in Brussels homes. We duplicate lever keys, dimple keys and European profile cylinder keys on site. The copy is produced in just a few minutes from your original key.

Security keys and patented keys

High-security cylinders use key profiles that are protected by patent. We work with Fichet, Bricard, Vachette, Mul-T-Lock, Picard and Wilka for the duplication of patented keys. These keys can only be copied when the ownership card supplied with the cylinder is presented.

Building keys and badges

Our technicians also duplicate communal entrance keys for apartment buildings, master keys for property managers and the magnetic badges and transponders used in Brussels residences and condominiums.

Mailbox and cellar keys

We copy mailbox keys (Renz, Decayeux and other models) as well as tubular keys and pin-tumbler keys for cellars and garages.

Security Keys: The Card Is Essential

For every patent-protected key, duplication is only possible when the ownership card is presented. This document, handed over when the cylinder is installed, proves that you are the rightful owner of the lock. It is a critical security measure that prevents any unauthorised copying.

If you have lost your ownership card, our team can guide you through the process of obtaining a replacement from the manufacturer. Depending on the brand, we can also replace the cylinder entirely with a new set of keys and a new card.

  • Fichet: card required for the 484, 787 and 690 series
  • Bricard: card required for Chifral S2, Serial S and Dual XP keys
  • Mul-T-Lock: card required for Interactive+ and MT5+ profiles
  • Vachette: card required for Radial NT and Radial NT+ cylinders
  • Picard: card required for Vigie and Diamant models
  • Wilka: card required for DIN-certified cylinders

Always store your ownership card in a safe place, separate from your keys. If your keyring is stolen, this precaution prevents a third party from duplicating your security keys.

26 Key Brands Available

We cover a wide range of brands to handle every lock installed across the Brussels region. Our workshop carries the blanks and key-cutting machines needed for more than 26 key brands, from the most common models to high-security profiles.

Among the brands we handle on a daily basis:

  • Fichet: Fortissime, Vertipoint, Spheris cylinders
  • Bricard: Bloctout, Supersureté, 8161
  • Vachette: V5, Axi'Home, Assa Abloy

  • Wilka: 1433, 1435, 1436, 5490, 5495 series

Frequently asked questions

Can you duplicate security keys with a card?
Yes, we duplicate patented keys with ownership cards (Mul-T-Lock, Abloy, EVVA). You must present the original card. Delivery: immediate to 48h depending on model. Keep your ownership card in a safe place — without it, even the manufacturer cannot duplicate the key. If you have lost it, we can replace the cylinder and provide you with a new set of keys and a new card.
How do I know the price of a key copy?
Visit our shop or call us at 0495 205 400. The price depends on the key type (standard flat, security, car). Immediate and free quote. To speed things up, send us a photo of both sides of your key via WhatsApp — we identify the model and give you the exact price within minutes.
Do you duplicate car keys?
Yes, we duplicate car keys with remote and transponder. On-site programming for most brands. Delivery: usually immediate. We cover common brands (Volkswagen, BMW, Mercedes, Renault, Peugeot, Citroen...) at rates significantly lower than dealerships, with the same result.
Can I make a copy without the original key?
Yes, it's possible from the lock number or by removing the cylinder. Our technician decodes the mechanism by reading the pins one by one (or reading the number engraved on the cylinder body) to reconstruct the exact key profile — a process that takes 15 to 30 minutes depending on the cylinder's complexity. For security keys (patented), the ownership card is the only option: without it, neither we nor the manufacturer are authorised to duplicate the key, as the patent protects against unauthorised copying. Allow 24 to 48 hours for security keys ordered through the manufacturer. We often see customers who have lost their only key. That is why we always recommend making a spare as soon as you install a new cylinder and giving it to someone you trust.
