The new circular keyhole, now standard on the exterior of all Doorblock door models, reflects a more understated and contemporary style.
Its minimalist design, integrated into the door leaf, means it barely protrudes from the door's surface. The cylinder is slightly recessed for a cleaner, more secure appearance.
This functional and discreet concept is designed for architecturally significant doors, prioritizing visual continuity, formal restraint, and coherence with contemporary design solutions.
