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.
