powdered graphite lube is great for locks. However, once its gummed up it doesnít help all that much. Dylanjunk, once you get the cylinder cleaned out spaying some powered graphics lube in the cylinder is a good idea.
btw, donít use WD-40 in lock cylinders or any liquid based lubes. They will retain moisture and/or dirt making things worse over time.
