What is the reason for the clicking sound when the one-touch start fails to ignite?

The reasons for the one-touch start failing to ignite with a clicking sound are: the car battery is low on power and cannot drive the starter; the starter is faulty and cannot drive the engine to start; the starter electrical components are faulty and need to be inspected and repaired at a repair shop. Here is some related information: One-touch start: The one-touch start device in a car is part of smart car technology, a button device that simplifies the ignition process and can also turn off the engine. Unlike traditional mechanical key ignition methods and conventional starting procedures, the one-touch start allows you to start or turn off the engine by simply pressing the one-touch start button. One-touch start functions: automatic door locking; automatic window closing; automatic anti-theft; one-touch start; one-touch shutdown; automatic door locking before driving; automatic unlocking when parking and turning off the engine; trunk opening function.
I've experienced this issue quite a few times. The clicking sound during one-button start usually indicates severely insufficient battery charge or aging failure, causing the starter motor relay to malfunction. If after multiple attempts the lights come on but the car won't start, with loud clicking noises, it's very likely a dead battery - especially common in winter. I'd suggest first checking if the battery voltage is below 12V using a multimeter. If you don't have tools, check if the battery warning light on the dashboard is illuminated. Additionally, the instantaneous current demand during startup is very high, and old batteries can't handle it, resulting in that sound. Avoid continuous starting attempts to prevent circuit damage - directly call for roadside assistance to jump-start or use a portable power bank for emergency. Pay regular attention to battery maintenance: don't drain power by running AC or audio after turning off the engine, and replace it every two years to prevent such embarrassing situations.
When it comes to the issue of push-button start not working accompanied by a clicking sound, I've found during repairs that it's often due to a faulty starter motor or poor wiring connections. The clicking noise is actually the solenoid trying to engage but getting stuck, which could be caused by insufficient battery power, worn motor brushes, or loose terminal connections. If you've ruled out battery issues, try pressing the start button a few more times with the car in Park, or gently tap the starter motor location. If that doesn't work, you'll need to check the fuses, relays, and related control modules, as faulty components here can cause current fluctuations. I recommend getting a professional diagnosis promptly to prevent minor issues from turning into major repairs. Regularly cleaning battery terminals and ensuring the alternator is functioning properly are also crucial.
