To install the Łucznik E6 30/30 door cylinder, first remove the existing cylinder by unscrewing the fixing screw located on the side of the door leaf. Insert the new cylinder into the lock mechanism, ensuring it is centered correctly. Once inserted, re-tighten the fixing screw until the cylinder is firmly secured in place. Test the operation with the provided keys from both sides of the door to ensure smooth rotation and latch engagement before closing the door.

What to consider before purchase

• Verify the required cylinder size by measuring your current lock from the center of the fixing screw hole to both ends.
• Ensure the door lock mechanism is compatible with standard Euro-profile cylinders.
• Check the door thickness to confirm that a 30/30 configuration provides sufficient reach.

For optimal performance and longevity, avoid using excessive force when turning the key. Keep the internal mechanism clean and consider applying a specialized dry lubricant if the operation becomes stiff over time.
