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.

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.

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.
