What is the reason for the car remote not responding and the car not starting?

Detailed explanation of the specific reasons why the car remote does not respond and the car fails to start: Strong magnetic field interference causing no response: During use, avoid exposing the smart remote key to strong magnetic fields. For instance, try to avoid parking the vehicle near high-voltage power lines, transmission towers, or other areas with strong magnetic signals. Since smart keys use low-intensity radio waves, they may not function properly when subjected to magnetic interference. Damaged smart key causing no response: Dropping or throwing the smart key can lead to poor contact, even if the outer shell is thick. Therefore, it is advisable to avoid dropping or throwing the smart key during use.
When I first encountered this issue, the most common cause was a weak car battery, especially during winter or after the vehicle hasn't been driven for a long time. The battery powers the remote control and ignition system. If the voltage is too low, the remote buttons won't respond, and the engine won't crank when trying to start—you'll just hear clicking sounds. I've experienced this myself when I forgot to turn off the headlights, which drained the battery. Temporary solutions include getting a jump start from another vehicle or using a portable charger for a while. To prevent this, regularly take long drives or check that all lights are off after parking. Car batteries typically last three to four years, so replace them when due. Another possible factor is the key itself—if the remote's battery is dead or the circuit is faulty, it can't deactivate the anti-theft system, preventing the car from starting. Try replacing the battery, making sure to get the correct model. If these aren't the issues, the vehicle's anti-theft system might be falsely detecting a fault. In that case, visit a repair shop for a computer diagnostic—don't delay to avoid breaking down on the road.
