Why is the car's one-button start not responding?

[SanAdrian]

Car's one-button start not responding reasons are: 1. Poor internal contact of the one-button start button or poor contact of the button plug, resulting in the inability to start the vehicle normally; 2. Starter issues, such as open circuit of the starter electromagnetic clutch or poor contact of the starting circuit, can cause the vehicle to fail to start normally; 3. Poor contact between the body and engine ground wire, or open circuit of the ground wire, leading to the inability to start the vehicle; 4. Damage to the engine speed sensor causing the vehicle to fail to start; 5. Damage to the low-pressure fuel pump, preventing the supply of fuel to the vehicle; 6. Battery depletion, resulting in the inability to start the vehicle; 7. Smart remote key battery dead, unable to open the car door, leading to the inability to start the vehicle.
