Damn right it was ???????????
I'll add, it might be partially my fault. The key has a small gash in it from when the flywheel fell off, and most likely weekened it. But I said, "Naaaaaahhh FACK it" and we're here lol. That's exactly why the key sheared (it split exactly where the the gash was).
Wait, wut? When the hell did the flywheel fall off with enough force to crack the key?
