Ok... I got out my seran wrap, hunted down my dremel tool, bought a crap ton of new bits, grabbed my screwdriver and began as that thread suggested. After securing the tank with plastic wrap and a towel, I forced those little crews loose carefully. That is when I noticed all of the little springs grinning maniacally; quietly chanting, "Free at last!!!" I stopped to reassess my situation.
I'm not sure if this article was for the 2012 variant or not. It seemed very clear that if I proceeded the gas cap would oblige my curiosity by exploding into a million peices. I opted for a, possibly, less successful route.
I carefully squeezed the grease into the lock mechanism from any angle that I thought I could grease and wiggled the key a lot.
SUCCESS!!!! After about 1 nickel sized drop, the lock moves almost like new. This stuff is not suppose to dissolve in gas. It is very tacky. Even if this only lasts a few thousand miles between reapplication, I think this is still the best solution for cost/implementation.
I'll let you know when it starts to get crunchy again.
