1:
One box is big, the other is small.

The keyhole in the big box is larger than the key to the smaller box. So, I
pick up the larger box, shake it around a bit, till the key to the smaller
box falls out through the keyhole of the larger box. Click, clack, and we
are done.

2:
The big box is big and heavy. The small box is frail. I use the big box to
smash the small box, extract the key from the wreckage, open the big box.

Alternative; it's a hardcopy version of The Spike, suitable for box
smashing.

3:
Ah hah! Thought of this while typing the other two.
One box is the room we are in, with a locked door; the other is a little box
in the floor. The key to the little box is on the floor, the key to the
larger one is in the little box.

Actually, I think the box-smashing answer is the most likely to work.
