It may be due to a dead key battery or other electromagnetic interference, signal interference, etc. Here are some related extended information: 1. Dead key battery: First, check if the car key still has power, or it might be due to poor battery contact. Solution: Try replacing the car key battery or take the car key for repair. 2. Other electromagnetic interference: There may be other signal interference sources. Sometimes, placing a phone together with the car key can also cause interference, and the car's dashcam may interfere with the car key as well. Solution: Place the key in a separate location and try starting the car again. If it still doesn't work, then check the transmitter and receiver.

When the BYD L3 doesn't recognize the key, I think the common solutions are: first, replace the key battery—a new CR2032 can be easily bought at a convenience store; then check if the car battery has enough charge, as low power can cause system failure; if that doesn’t work, try restarting the engine—turn off all electrical devices and wait a few seconds before restarting; sometimes it’s antenna interference, so avoid placing the key near phones or metal objects; finally, go to a 4S store for professional diagnosis—don’t delay and turn it into a bigger issue, safety first. Prevention is better than repair.

What is the function of the front oxygen sensor in a car?

The function of the front oxygen sensor in a car is to detect the oxygen content in the exhaust gases produced after the combustion of the air-fuel mixture in the cylinders. Generally, a high oxygen content indicates a lean mixture, while a low oxygen content indicates a rich mixture. The front oxygen sensor transmits different electrical signals to the ECU based on the varying oxygen levels, allowing the ECU to adjust the air-fuel mixture accordingly. Symptoms of a faulty front oxygen sensor: When the front oxygen sensor fails, the ECU cannot obtain information about the oxygen concentration in the exhaust pipe, and thus cannot perform feedback control on the mixture concentration. As a result, engine fuel consumption and exhaust pollution increase, and the engine may exhibit symptoms such as unstable idling, misfiring, and surging.

How many kilometers should truck tires be replaced?

There is no fixed time, it depends on the wear condition of the tires. Generally, they should be replaced when they reach the wear limit. Tires are a major consumable for transport vehicles and cannot be replaced based solely on mileage. The common practice is to check the tread depth or wear limit indicators. If the tread is too shallow or has reached the wear limit indicators, the tires should be replaced. Some methods for maintaining car tires are as follows: 1. Method 1: Regularly check tire pressure. 2. Method 2: Avoid hitting obstacles. 3. Method 3: Stop using tires when they wear down to the wear indicators. 4. Method 4: Wheel alignment and balancing. 5. Method 5: Protect tires from damage caused by sunlight, oil, acid, and hydrocarbons. 6. Method 6: Rotate tires.
