When The Doctor first meet with River Song, she pretended he could open the TARDIS by snapping his fingers :
[...] But not "my" Doctor. Now my Doctor, I've seen whole armies turn and run away. And he'd just swagger off, back to his TARDIS. And open the doors with a snap of his fingers. The Doctor. In the TARDIS. Next stop: Everywhere.
-Professor River Song, Doctor Who, series 4 episode 9 Forest of the Dead
He successfully did it shortly after that and he also did it in the first episode of series 5 The Eleventh Hour. But I don't remember him doing so recently. Did I miss something or he just forgot he could do it?
