Why does my car make rapid clicking when I turn the key?
Rapid clicking when turning the key typically indicates that the battery has enough power to engage the starter solenoid, but not enough to spin the engine. Based on driver experiences, even after attempting a jump-start or verifying battery connections, this symptom can stem from a failing starter motor, a poor ground connection, or a battery that has failed under load despite showing surface voltage.
