I've been seeing this little key symbol flashing on my Nissan dashboard for days and it was driving me nuts. Turns out it's just telling me my key fob battery is getting low. I swapped out the old CR2032 coin cell battery and now the warning light went away completely. Much cheaper than a trip to the dealership.
