What to Do When the Key Fob Battery for the New Sylphy's Push-to-Start System Dies
4 Answers
When the key fob battery for the New Sylphy's push-to-start system dies, you can either replace the battery or use the mechanical key. In case the key fob battery is dead, press the side with the logo firmly against the push-to-start switch for a few seconds, then press it directly—this is designed as a backup for when the key fob battery runs out. The Sylphy is a model under Dongfeng Nissan, with body dimensions of 4641mm in length, 1815mm in width, and 1447mm in height, and a wheelbase of 2712mm. The Sylphy adopts the family VMotion 2.0 design language. Thanks to Nissan's global CMF platform, which features a longer and wider chassis structure, the Sylphy achieves a 1.254 luxury car width-to-height ratio, along with a 0.26Cd ultra-low drag coefficient, while its 1.5Gpa UHSS high-rigidity body structure ensures enhanced driving safety.
I've been driving a Sylphy for many years, and it was really frustrating when the key battery died last time, but it's actually simple to handle: When the remote key for the new Sylphy runs out of battery, you can first use the small mechanical key hidden inside the key fob to open the door—usually inserting it into the door handle's lock cylinder will unlock and let you in. Once inside, don’t panic. Locate the push-start induction area below the right side of the steering wheel (typically near the start button), place the dead key close to it, then press the brake and hit the start button—the car will start. I recommend changing the key battery every two years; the model is a CR2032 lithium battery, which costs just a few bucks online and is easy to replace. If you're unsure how to do it, the Sylphy manual has detailed steps, or you can simply visit a Nissan dealership to have them replace it for you—quick and safe. A dead key isn’t a major issue, but timely action can avoid being stranded and disrupting your trip.
I bought my Sylphy two years ago, and I was also at a loss when the key suddenly malfunctioned. Later, I learned a few tricks: if the battery of the one-button start key is dead, quickly try the spare key. If that doesn't work, use the mechanical key to open the door and sit inside, then locate the start induction area (I checked the manual and it said it's near the center console), press the key against it and hit the start button. The key is to always keep a few spare CR2032 batteries in the car for emergencies—these small batteries can be bought at any hardware store. If even the induction start fails, it might be a key circuit issue or a drained car battery, and you'll need to visit a professional repair shop for inspection. I recommend new owners avoid placing the key in high-temperature areas to extend battery life—I've made this a habit myself, which has significantly reduced malfunctions.
For new drivers, a dead key fob in a Nissan Sylphy can be quite troublesome. Through trial and error, I found that you can first use the mechanical key to open the door and get in the car, then follow the manual's instructions to place the key near the push-button start's induction area. While pressing the brake pedal, push the start button to ignite the engine. Replacing the battery isn't difficult either—just buy a CR2032 coin cell and swap it out in a few minutes. To avoid this situation, regularly check the key fob's indicator light or test the remote control's range monthly to see if it's getting shorter. Simple maintenance can save you a lot of hassle. If the induction start fails, remember that most Sylphy models support key fob reprogramming as a reset option, or you can drive directly to an authorized dealer for inspection to ensure safety.
