## Long description

NUKI Cisa Astral S 35/40 is a door lock cylinder with a 35/40 mm profile designed for standard euro-profile locks. It is intended as a mechanical key cylinder compatible with Cisa Astral S fittings and fits doors that require a 35 mm inner / 40 mm outer dimension. The cylinder provides conventional key access and is suitable as a direct replacement for worn or damaged cylinders in residential and light commercial doors.
Advantages
The cylinder offers a precise fit for doors that need a 35/40 mm euro-profile cylinder, allowing straightforward replacement without modifying the existing lock case. Its mechanical operation ensures reliable key access independent of electronics, and compatibility with Cisa Astral S profiles facilitates installation and interoperability with existing hardware. The product is suitable for both maintenance and upgrade scenarios where a standard-profile cylinder is required.
Suitable for
 Replacing worn or damaged euro-profile cylinders in residential doors
 Upgrading standard locks to a compatible Cisa Astral S cylinder
 Application in light commercial doors where mechanical key operation is needed

Key specifications
 Cylinder type: Euro-profile (asymmetric) mechanical key cylinder
 Dimensions: 35 mm (inner side) / 40 mm (outer side)
 Operation: Mechanical key entry and exit
 Compatibility: Fits Cisa Astral S standard euro-profile lock cases
 Intended use: Residential and light commercial doors
How to use
To fit the cylinder, remove the fixing screw from the lock case, extract the old cylinder and insert the NUKI Cisa Astral S 35/40 so that the cam aligns with the lock mechanism. Tighten the fixing screw to secure the cylinder and check smooth key operation on both sides. Ensure the cylinder length matches door thickness and that the asymmetric 35/40 dimensions are oriented correctly for inner and outer sides before final tightening.
Usage recommendations
Check door thickness and existing lock case compatibility prior to purchase. Use a properly sized fixing screw and test the key turn operation several times after installation. For increased security, consider pairing the cylinder with a reinforced escutcheon and periodic maintenance such as light lubrication of the core using products recommended for lock mechanisms.
