Setup, Compatibility & Care
Installation requires a Phillips head screwdriver. Before purchasing, you must measure your current cylinder: measure from the center of the fixing screw hole (the cam) to the outer edge of the door on both sides. This ensures the cylinder does not protrude beyond the door handles, which is critical for security. To care for your cylinder, avoid using heavy lubricants like oil, which can attract dirt; instead, use a graphite-based powder lubricant if the key action becomes stiff after several years of service. Periodically check that the fixing screw remains tight to prevent cylinder movement.
