## Long description

NUKI Cisa Astral S 35/35 is a lock cylinder designed for electronic door locking systems that require a symmetric 35/35 profile length. The cylinder functions as the mechanical component within compatible smart lock setups, providing physical key access alongside electronic control. It is intended for use where the door thickness and hardware demand a centrally balanced cylinder and where compatibility with NUKI smart locking solutions and Cisa Astral S profile standards is required.
Advantages
The cylinder provides precise mechanical operation and a balanced 35/35 length for doors that need symmetric fitting. It maintains conventional key access while integrating with electronic locking systems, enabling dual-mode entry. The design follows widely used profile dimensions to simplify replacement or integration into existing door hardware without extensive modifications.
Suitable for
 Residential exterior and interior doors with 35/35 profile requirement
 Commercial doors where a symmetric cylinder length is required
 Smart lock installations that combine electronic actuation with mechanical key override
 Replacement of existing Cisa Astral S cylinders with the same profile
Key specifications
 Symmetric profile length: 35/35 mm
 Profile type: Cisa Astral S compatible euro cylinder profile
 Function: Mechanical cylinder for electronic smart lock systems (mechanical key access and override)
 Application: Suitable for doors requiring centered cylinder installation
 Material characteristics: durable metallic construction suitable for standard door hardware (finish depends on manufacturer options)
How to use
Install the cylinder into the door following the manufacturer’s fitting instructions for a euro profile cylinder of 35/35 length. Ensure the cylinder sits flush and that retaining screws are the correct length for the door thickness. After mechanical installation, integrate the cylinder with the compatible smart lock or electronic actuator according to the smart lock system’s setup guide to enable electronic locking and mechanical key override. Test both electronic operation and key turning to confirm smooth engagement and alignment.
Usage recommendations
If replacing an existing cylinder, verify door thickness and backset to confirm a symmetric 35/35 cylinder is appropriate. Use suitable retaining screws and tighten to manufacturer torque specifications. Periodically lubricate the cylinder with a recommended lock lubricant and inspect for wear. For integration with a smart lock, follow both cylinder and smart lock manufacturer guidelines to ensure compatibility and secure operation.
