How to solve the yellow key light on the new Sylphy?
2 Answers
The solution for the yellow key light on the new Sylphy: you can replace the key battery. If the dashboard still shows a warning after replacing the key, it is recommended to have it inspected at a 4S shop. The yellow key light on the new Sylphy indicates that the vehicle's computer cannot detect the key or it may be due to a low battery in the key. The body dimensions of the new Sylphy are 4631 mm in length, 1760 mm in width, and 1503 mm in height, with a wheelbase of 2700 mm. The new Sylphy features front-wheel drive, a MacPherson strut front suspension, a torsion beam rear suspension, and a unibody structure.
When the yellow light on my new Sylphy key lit up, I panicked a bit, as it's a crucial item for daily driving. At first, I thought the key was broken or there was some major issue with the car. Later, after consulting a friend, I learned it was most likely just a dead battery. The key uses a CR2032 battery, which is super cheap and available at supermarkets or online. I replaced the battery myself: first, locate the small opening on the key, use a coin to pry open the shell, carefully remove the old battery (mind the polarity), insert the new battery, and snap the shell back together. After the replacement, the light stopped glowing, and the car remote worked fine. It's important to regularly check the battery life—the yellow light indicates low power, so don’t wait until it completely dies to act, or you might end up stuck unable to open the car door.
