A home is personal. It deserves protection that reflects that.
Our keys are manufactured from solid stainless steel. They do not break under daily use, and they do not wear like conventional materials. Their construction prevents unauthorized duplication. Unlike conventional nickel silver keys, which may contain nickel or lead and can trigger skin reactions in sensitive individuals, stainless steel offers a durable and skin-friendly alternative.
Our cylinders are engineered to resist mechanical manipulation and chemical attack — including acid exposure. Security, for us, does not begin with a claim. It begins with material integrity and engineering discipline. A system must function reliably for decades — in everyday life and under stress.
Security should not create complexity.
You receive a complimentary AMADEO account including an APP. We structure and plan your system in a way that allows self-installation, while providing long-term support. Whether a private residence, multi-unit property, or extended family structure — each system is configured precisely and organized clearly. A nationwide network of service partners is available to assist with questions or technical matters. If a key is lost, control remains intact. The system can be adjusted without replacing the entire installation. Extensions or digital upgrades can be integrated at any time. Reliable support. Clear processes. Long-term availability. Security is not a one-time decision. It is a lasting responsibility.
Your Unique Stainless Steel Identity
An AMADEO key is precision-cast from solid stainless steel, corrosion- and acid-resistant, and free from lead and nickel — durable, low-allergen, and built for daily use. Each key is a unique original and patented , protected by 96-bit digital encryption to prevent unauthorized duplication. Only you can reorder or extend its functionality via your secure app, and no information on the key reveals your property. Designed as a reversible key with an ergonomic grip, it ensures effortless handling, with optional NFC integration or color marking available.
Hygiene begins with the choice of materials.
The Cylinder – The Core of Security
The cylinder is not merely the place where a key is inserted.It is the central element of both physical and organizational security at the door. FREEFLEX combines patented mechanical precision with digital system logic. Each cylinder is engineered for resistance — against mechanical manipulation such as pulling or drilling, against forced attacks, and against chemical exposure, including acid. At its core operates a binary-coded disc system with 12 spring-loaded locking discs. The key is verified simultaneously from both sides in total of 96 digital data points. The cylinder housing is modular and extendable and contains no moving locking elements.
The cylinder is not a component. It is the security authority of your door.
