Earlier today, my "T" key popped off! Now, I have extended warranty, but I'm not in a country where there are Apple stores. It's a late 13 MBPr, with key mechanisms that look like this: Now, I watched this video: and when he latches the bottom portion, he then pushes on the top portion and there's a click, which is non existant on mine. I then put the "T" back on, and it's very wobby and comes right back off. Anyone have any advice? I don't want to spend $10 on a replacement mechanism when I'm not sure that's the reason.
