What is the reason why the Teana car cannot start with one key?

The reasons why the Teana car cannot start with one key are: 1. The fuel filter is clogged; 2. The fuel pump filter screen is clogged; 3. Whether the spark plugs have severe carbon deposits or are burnt; 4. The starter motor is not working; 5. The fuel pump does not supply fuel in time during cold start; 6. Insufficient fresh air or insufficient fuel supply; 7. The gear was not returned to P gear when parking; 8. The smart key is out of power; 9. The battery is out of power or the battery life has expired. The Teana is a mid-size car launched by Dongfeng Nissan, with a length, width, and height of 4901mm, 1850mm, and 1450mm respectively, and a wheelbase of 2825mm. It is equipped with a 2.0L naturally aspirated engine and a 2.0T turbocharged engine, with maximum power of 115kw and 179kw respectively, matched with a CVT continuously variable transmission and a CVT continuously variable transmission (simulated 8-speed) gearbox.
I often encounter issues with the one-touch start in my Teana. Once, I almost missed a date because the car didn't respond when I pressed the start button, and I was sweating with anxiety. Later, I realized it might be due to a dead key fob battery, as the key needs to transmit a signal to the car for recognition. An old battery can weaken the signal, but replacing it with a new one improved the situation significantly. Another possibility is insufficient car battery power, especially in cold weather, which makes the problem more likely to occur. Last time, my car failed to start after being parked for a week. It's also important to check the key's position—avoid placing it in a bag or near a phone that might cause interference. You can test the key's signal strength yourself or try pressing the brake pedal and restarting. Maintaining the battery's lifespan can save a lot of money, so it's best to check the voltage monthly to avoid unexpected issues. In short, don't panic—most problems are minor, but neglecting them for too long could lead to a frustrating breakdown on the road.
There are several reasons for the malfunction of the Nissan Teana's one-touch start system. Based on my personal experience, key sensing issues are the most common, such as a depleted battery or a faulty key antenna causing signal reception failure. Alternatively, an unstable car power system or low battery voltage can trigger system protection, preventing startup. Once, my car wouldn't start in cold weather, but charging the battery fixed it. Before starting, ensure the key is in the designated position inside the car and not too far away. Self-diagnosis is simple: try starting with a spare key; check the dashboard for error messages. For maintenance, regularly clean the key interface to avoid dust buildup. If these steps don't work, the control module might have a bug requiring professional scanning. Don't overlook minor issues, as they can affect the entire vehicle's electronic systems. Regularly use the cigarette lighter charger to maintain voltage.
