To install the lock, remove the existing cylinder by unscrewing the fixing screw located on the edge of the door. Insert the new ABUS 40x40mm cylinder into the lock case, ensuring it is centered correctly. Once aligned, reinsert and tighten the fixing screw until the cylinder is firmly secured. Test the operation with the provided keys from both sides of the door before closing it.

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 thickness is compatible with the 40x40mm dimensions.
• Check if your door hardware is compatible with standard double cylinder profiles.

For optimal performance, ensure the lock is kept clean and free of debris. If the key operation becomes stiff over time, use a dedicated graphite-based lubricant rather than oil-based products to maintain the internal mechanism.
