The reasons why the Teana car cannot start with one key: The keyless start system has an authentication area, and the car must detect a valid key within the effective area to start normally. If it is beyond this area, it cannot start normally. In addition, you need to check the battery level of the car key. If the battery level is too low, it will also affect the normal start of the car. The Teana is a flagship mid-to-high-end luxury sedan under NISSAN. The corners of the headlights are treated extremely sharply, and the arc of the integrated bumper on the body rises from both sides to the outside of the headlights, then naturally extends from the outermost edges of the headlights to form a smooth waistline that runs through the front and rear, paired with a rounded arc roof, making it natural, smooth, dynamic, and very stylish.
I once encountered a situation where my Teana couldn't start with the one-touch start, and it felt really awful. There could be several possible reasons, the most common being a dead remote key battery. Try replacing it with a new one; you can buy them for just a few bucks on the market. Sometimes, a low car battery can also cause this, especially in older cars or after prolonged parking in winter. Check if the key is near the driver's seat—it needs to be in the right position to avoid interference, like strong magnetic sources nearby. The one-touch start system relies on electronic signals, so key malfunctions or battery issues can easily cause it to fail. Remember to try locking and then unlocking the car first; it might reset the system. Regular maintenance of your car battery and periodic replacement of the key battery can help reduce such embarrassing situations. If these solutions don't work, it might be a faulty start button or wiring issue, in which case you should take it to a professional shop for inspection—after all, safety comes first, so don't take it lightly.
