New Nissan Sylphy key yellow light solution is to replace the key battery. The yellow light on the Sylphy key indicates that the car computer cannot detect the car key, or the key battery is dead. If the dashboard still shows a warning after replacing the key, it is recommended to have it inspected at a 4S shop. In terms of exterior design, the new Sylphy closely follows contemporary trends. The modified front grille resembles the new-generation Teana more closely, with the enlarged grille giving the car a more imposing appearance. The waistline running from front to rear makes the new model look more dynamic. While maintaining the smooth, full, and rounded style, the exterior appears more rugged, with softer lines, and the overall design tends to be more youthful.
When I first drove the new Sylphy, I encountered the issue of the key yellow warning light. Most commonly, it's just the key battery running out. You can easily fix it by replacing the CR2025 coin cell battery yourself, which you can buy at any supermarket. If the light stays on after replacement, the system might be stuck—try turning off the engine, waiting for 5 minutes, and then restarting the car. Another time, my key got damaged from a fall, affecting the internal chip, and I had to visit the 4S shop to pair a new key, which cost a few hundred yuan. The yellow light is a warning; don’t ignore it and avoid driving, as you might end up stranded if the car won’t start. I now regularly replace the battery as a preventive measure and recommend keeping a spare key in the car for convenience and practicality.
My family also uses the new Sylphy. If the yellow light on the key is on, the first thing to check is the battery. It's very convenient to replace it yourself if it's out of power—just buy a cheap battery and try replacing it. If the light is still on after replacement, press the key button to see if the car responds. If there's no response, try starting the car with the spare key. If that doesn’t work, go to a repair shop immediately for inspection. Don’t waste too much time—safety comes first. Once, when I was rushing to take my child to school, the key light came on, and replacing the battery fixed it, saving a lot of hassle. It’s best to replace the battery once a year to prevent this issue.
