There's clearly grease at the end, but I don't see any on the tumblers, if that's even the right term for what we're looking at.
Maybe @ToyotaMatt has some idea how they're greased from factory. He's been posting a lot about keys lately.
I can tell you that I recently improved a Honda motorcycle lock cylinder by cleaning it with brake cleaner shot into the key-way, running the key in and out, turning it several times, followed by some graphite Lock-Ease aerosol. Unless corrected by a Toyota expert, I'll go with what I've always been told: use graphite for lock cylinders.
