What to Do When Turning the Key Doesn't Start the Car?
2 Answers
When turning the key doesn't start the car, you should check whether there is electricity in the live wire entering the ignition switch and whether there is electricity in the live wire of the starter motor solenoid. Below is some relevant information about remote control keys: 1. Introduction: A remote control key utilizes the wireless remote function of the central locking system, allowing you to remotely unlock and lock the doors without inserting the key into the lock. 2. Working Principle: Simply put, the working principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU, Electronic Control Unit) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the action of locking or unlocking.
As a veteran driver with decades of experience, I've encountered several situations where turning the key didn't start the car, which can be really frustrating. Most of the time, it's a battery issue—either an aging battery leaking power or corroded/loose battery terminals causing insufficient power supply. Another possibility is a faulty starter, especially if you hear a slight clicking sound when turning the key but the engine doesn't respond, which points to starter trouble. My usual first step is to check the battery terminals: inspect the positive and negative connections for looseness or corrosion, and try tightening them with a wrench. If that doesn't work, I’ll ask a kind stranger for a jump-start using jumper cables, which often does the trick. If it still won’t start, don’t force it—contact a professional repair shop right away, as they have the tools to diagnose the exact issue. Regular maintenance, like replacing the battery periodically and checking the electrical system, can help avoid such headaches.
