Ignition tumbler suddenly won't turn, both ignition + door locks, multiple keys

Hey all, I want to make sure I'm not missing something obvious on this one. My 300SD sat most the winter. I went to start it up for the first time the other day and I was unable to turn the key past the first click. No accessories and unable to warm the plugs/fire the ignition. This was the first instance of any key/tumbler/ignition issues in 12+ years. Eventually got it to turn using graphite lubricant and once it does, everything seems fine. Start and stop the car no issue. But as soon as you pull the key out it's back to the graphite and the whole process starts over. Same if not worse with my spare key (it's less worn). The issue seemed fairly localized...until I went to lock the doors, which I seldom do, and I wasn't able to turn that tumbler either. Thoughts?

Thank you,
