Graphite lubricant is only good on tracks such as on sliding doors. My father owns a deli and puts Dry Graphite lubricant on his sliding refrigerator door tracks. Liquid lubricant will get ugly after some use and traps particles (like flour) and gets a little tricky to clean up. Graphite wouldn't be good on any part of a door lock system because it needs to be applied every so often, it doesn't "stick" like liquid lubricant and that would be a pain in the neck to do to the internal door mechanism. That is probably why it was easy to put your key into your keyhole on your other car for some time then it went back to being difficult. As for having moisture in it? Maybe true but if it was, as I applied the lubricant to the tracks I would have expected the graphite to be clumped together as I poured it out.
