They are. Most locksmiths hate graphite. The two lubes most used and recommended by locksmiths are Houdini and Tri-Flow. The latter is available in some hardware stores (it’s in the lube section of my local ACE Hardware), and while you can special order Houdini online, you can also buy it locally under its alternate name Super Slick Slick Stuff. I’ve seen it in my local Lowes, not sure if Home Depot also has it now.
