fix Nissan key symbol 2

While trying to fix the Nissan key symbol, I found that the yellow key with a car outline on the dashboard usually means the key fob battery is low or the key isn't being detected properly. Replacing the coin cell battery inside the fob fixed it for me, and the symbol went away after a short drive.
