    Did you mean Nxd2? There is nothing on d4 for K to x

    Re4, Rf4 and Rg4 don't work because then he's in the way of B1, B2 or Q for one of the above examples

    Your key move is much too mundane to be the solution.
    Okay, I see.

    He must have put a lot of time in to come up with that mate in 2 puzzle.

    A pleasant problem. The bPa3 drew my attention. It isn't needed in the initial position, as either 1 ... Na3 or 1 ... Nd2 would be met with 2 B(x)d2. Why, then, did the composer wish to prevent 1 ... Na3? The answer is that 2 Bd2 does not occur post-key. 1 Rh4 Nd2 2 Bg7 is a self-block, but 1 ... Na3 wouldn't be, and 2 Bg7 would leave d2 unguarded.
