Tired of that annoying little key warning light on your Nissan dashboard? It usually means the key fob battery is low, especially in older models. Pop a fresh CR2032 battery in there, and make sure you're holding the key near the start button when you push it. Sometimes, a quick reprogramming sequence from your manual does the trick too. No more beeping, just smooth starts.
