Yay! Thank you!
I've told this story a million times here but I'll tell it again. I used to work at the service desk in a hardware store in high school. I re-keyed and fixed locks (mostly for landlords needing to rekey locks after an eviction). Every. single. spring. I got a pile of gummed up locks that won't work, won't turn. Why? They used WD-40 when they started to get hard to turn in the winter. Come spring, dust, pollen, who-knows-what all got sucked in by WD-40's magical crud magnets. Take it all apart, clean it out, and lube with graphite. WD-40 is NOT, is NOT (it's not) a lubricant. It has it's uses, but it shouldn't be used to lubricate parts. Use a LUBRICANT to lubricate parts!
Like you, I recommend graphite for a lock. Works great, and doesn't get gummed up on all the tiny parts.
