What Causes the Clicking Sound When Using One-Button Start?
2 Answers
The reasons for the clicking sound when using one-button start are: 1. Issues with the ignition system or fuel supply system; 2. Insufficient voltage or a dead battery; 3. An open circuit in the solenoid switch of the starter motor. The one-button start device is a part of smart cars, serving as a button mechanism that simplifies the starting process and can also be used to turn off the engine. This device can be installed in place of the original car key lock or as an independent panel modification. Typically, the smart key for one-button start also includes a serrated or grooved key, designed to allow manual starting in case the one-button start function fails.
Last week, my car also made a clicking sound when I pressed the one-button start, sounding like the engine was stuck and wouldn't ignite. The most common cause of this sound is insufficient battery power. When the battery ages or discharges after prolonged parking, it can't provide enough voltage to the starter motor, causing the motor to just click without turning. I've encountered this several times, and each time I first check the battery with a voltmeter. If it's below 12 volts, it's almost certainly the issue. Quickly get a jump start from a friend or use a portable charger as an emergency measure, then drive to a repair shop to replace the battery. To prevent this, always remember to turn off electrical devices when parking and regularly test the battery's lifespan during maintenance. If the clicking persists after charging, it might be a faulty starter relay or poor wiring contact, requiring professional inspection to avoid more serious circuit damage.
