Quick answer — AI summary
Patented security keys may only be duplicated by certified locksmiths who are partners of the key system, and solely on the basis of written authorisation from the registered owner. Ordinary keys (without a patent) can be copied at any locksmith or even in a DIY store — without any verification whatsoever. This distinction is crucial for anyone who wants to retain control over who has access to their home or business. Manufar exclusively supplies and manages patented systems.
Ordinary keys: anyone can copy them
A standard house key without a patent can be duplicated at any locksmith, hardware store or even via kiosk machines in shopping centres — without any verification of identity or ownership. That means a tenant, ex-partner or former employee could have a duplicate made unnoticed. You never know how many copies of your key are in circulation.
Patented keys: centralised control
A patented key features a unique profile and a serial number registered in the owner's name. The profile is protected by an intellectual property right: it may not be reproduced without permission. Duplicates can only be produced by certified partners of the key brand — and only after presenting a valid authorisation card or written consent from the registered owner.
How does the authorisation procedure work?
When purchasing a patented key system, the owner receives an ownership card or authorisation document with a unique code linked to the key's serial number. Need a duplicate? Simply present this document to a certified locksmith — the system's authorised dealer. Without that document, the request is refused. We register the owner during installation and provide the authorisation documentation in accordance with the chosen brand.
Which locksmiths are certified?
Not every locksmith is a certified partner for every key system. Well-known patented systems such as Mul-T-Lock, EVVA, KESO, Medeco and DOM work with a limited network of authorised dealers and installers. Manufar is a certified partner for several patented key systems — meaning you can rely on us for both installation and future duplicates.
Losing a key: what now?
If a patented key is lost, simply notify the owner and the installer. The lost key's serial number is deactivated in the system — any duplicates of that key are invalidated or blocked upon the next request. In most cases, no cylinder replacement is needed: a major advantage over non-patented systems, where loss always requires a cylinder swap.
Patented keys for businesses and apartment buildings
For businesses with staff turnover or apartment complexes with changing residents, copy protection is not a luxury but a necessity. With a patented system, every departure of an employee or tenant without a returned key poses no security risk — the key cannot be freely duplicated. This saves on cylinder replacement costs and boosts the building's long-term security.
Conclusion
The question "who is allowed to duplicate my key" is fundamental to the security of your home or business. With a patented system, you always have control — over every duplicate and every user.
