  The brain cannot adapt to such a small object making such a rapid movement
with one eye only. The visual clues are too subtle and too fast.

  Instead, put the keys on a table, and then walk from afar towards the
table with one eye covered, and take the keys. At least I don't have the
slightest problem in doing that. That's because the brain has time to
estimate the distance to the keys accurately while you are walking,
watching the keys.
