Dierre D‑UP Cylinder

The Dierre D‑UP cylinder is the most advanced mechanical security solution developed by Dierre. Designed to provide superior protection compared to traditional cylinders, D‑UP incorporates enhanced mechanical technologies that increase resistance to forced entry, manipulation, and destructive attacks.

At the core of the system is the next‑generation desmodromic coding mechanism, further improved over the New Power. The internal gorges remain in random positions when the key is not inserted, making techniques such as bumping, picking, and tracing ineffective. The structure is reinforced with a hardened anti‑pull bar, anti‑drill components, tempered steel pins, and an anti‑tampering trap that locks the cylinder in case of fraudulent attempts.

D‑UP uses protected, non‑duplicable keys with an exclusive Dierre profile and a security card required for authorized duplication. It is fully compatible with Dierre armored doors designed for European cylinders.

Choosing a D‑UP cylinder means equipping your home with a high‑end mechanical security system engineered to withstand modern intrusion techniques.
