Setup, Compatibility & Care
To install this cylinder, you must first remove the retaining screw located on the door edge, aligned with the bottom of the existing cylinder. Turn the key slightly to align the cam and slide the old cylinder out. Insert the Yale 1000 Series cylinder, ensure it is centered, and replace the retaining screw. Always measure your door thickness and the position of the screw hole from both sides before buying to ensure the 35/35mm size is appropriate. For care, avoid using heavy lubricants like WD-40, which can attract dust; if the lock feels stiff, a dry graphite powder lubricant is recommended to keep the pins moving freely.
