We do not recommend oil based lubricants, such as WD40, for use with any type of cylinder lock. Typically, such lubricants attract dirt and small particles which can result in the sticking and seizing of internal component parts.
This efficient and rapid drying spray lubricant has been specially developed by Swiss lock manufacturer KABA to provide long lasting lubrication and smooth lock operation with no oily residue to attract dirt and grime. Regular use will improve reliability and prevent wear of cylinder lock barrels, padlocks, vehicle locks and cam locks etc even in harsh, saline environments. A very popular choice with building maintenance departments.
