What does the 'key' in Teana mean?
2 Answers
In cars, 'key' refers to the situation where the key is not detected. The vehicle dashboard displays 'key' because the onboard computer cannot detect the signal from the key remote. Solutions include: 1. Press the lock and unlock buttons on the key; 2. Replace the key's battery. The basic components of a remote key consist of the following two points: 1. Transmitter: Composed of a transmission switch, transmission antenna, integrated circuit, etc., containing an identification code storage circuit and an amplitude modulation circuit, with a button-type lithium battery on the opposite side of the circuit. The transmission frequency uses radio waves, and pressing the transmission switch button once sends a signal. 2. Receiver: After the transmitter sends the identification code using shortwave modulation, it is received by the car's shortwave antenna and enters the shortwave high-frequency amplification processor of the receiver's electronic control unit via a distributor for demodulation, then compared with the demodulator's identification code.
The 'Tianlai key' typically refers to the Nissan Teana's smart key system. I personally just bought this car not long ago and am extremely satisfied with its convenience. You can get in and start the car without taking out the key – it automatically unlocks when you approach and pull the door handle, and starting is just a button press away, which is especially handy when your hands are full. I often show off this little piece of tech to my friends on the road, and it's even more safe and convenient to use in nighttime garages or rainy weather. However, be careful not to forget it in your pocket and wash it or drop it. The battery needs to be replaced about once a year, and it's easy to replace it yourself with a CR2032 coin battery. Occasionally, weak signals might be due to interference, but overall, it makes driving smarter and easier. For young people like me, it's a great helper in improving quality of life.
