To install the ABUS 54909, remove the existing cylinder by unscrewing the fixing screw located on the side of the door edge. Insert the new cylinder into the lock case, ensuring it is centered correctly, and secure it firmly using the original fixing screw. Test the operation with the provided keys from both sides of the door before closing it to ensure the mechanism engages and disengages smoothly.

What to consider before purchase

• Verify the exact measurement of your current cylinder from the center of the fixing screw hole to both ends.
• Ensure the door thickness is compatible with the 40x50mm dimensions.
• Check if your current lock hardware supports a double cylinder configuration.

For optimal performance, avoid using heavy lubricants inside the cylinder. If the key operation becomes stiff over time, use a specialized graphite-based lubricant to maintain the internal pins and springs.
