How to Start a Nissan Sylphy When the Key Fob Battery is Dead?
2 Answers
To start a Nissan Sylphy when the key fob battery is dead, follow these steps: 1. Press the engine start button to turn on the ACC mode (indicator light will illuminate). Then press the start button again - the button will turn green as the vehicle begins self-diagnosis. 2. After the self-check completes, depress the brake pedal and press the start button once more to ignite the engine. The Nissan Sylphy is a Class A sedan under Dongfeng Nissan, with dimensions of 4641mm (length) × 1815mm (width) × 1447mm (height) and a 2712mm wheelbase. It comes equipped with dual front airbags, side airbags, curtain airbags, speed-sensing auto door locks, crash-sensing auto unlock, LED high-mounted stop lamp, rearview camera system, and parking sensors.
Hey, I remember once when I was driving my Sylphy, the key suddenly malfunctioned and it was quite a panic, but there's actually a solution. First, check the remote key—there's a small mechanical key hidden on the back or side of it. Pull it out and manually open the door. Once inside, starting the car is crucial: for the Sylphy's keyless system when the battery is dead, you can simply hold the key close to the start button for about 10 seconds. The sensing position is usually the central cup holder or the slot below the steering wheel. If that still doesn’t work, try pressing the button multiple times or use the spare key. To prevent emergencies, I always keep a CR2032 coin battery in the car as a backup—it’s easy to replace by opening the key casing. Regularly checking the key’s blinking light can help detect battery aging early. This method works for many car models, so just make it a habit.
