How it works
The CISA Astral S DUO Euro profile double cylinder operates by aligning its internal pin tumblers using an authorized reversible flat key. Insertions from either end are possible even if another key remains inserted on the opposite side. Security features actively resist snapping, drilling, bumping, and picking attempts during use.
