Common causes of car starting clicking noise:

There are many different problems that can prevent your car from starting. Some of these problems can be easily fixed, whereas other require complex repair work.

If your car produces a loud clicking noise when the key is turned, this is likely due to a lack of electrical current. The keys will move freely, but the starter will not crank due to a lack of power from your car’s battery/charging system. Common causes of a lack of electrical current include:

Dead battery – A clicking noise when trying to start the engine is often associated with a flat battery. If you have left your car’s electrical accessories or lights on for a long period of time, the car’s battery may have been drained of energy. A jump-start will usually fix this problem, however, batteries can lose their ability to hold a charge over time and need to be replaced.

Corroded battery terminals

Dirty/corroded battery terminals – The terminals on your car’s battery can become corroded over time, reducing their ability to send an electrical current. If your car is not starting, inspect the battery terminals for build-ups of a blue,green or white powder substance. The corrosion can usually be removed with a screwdriver or similar tool, or dissolved with baking soda and warm water, restoring correct battery function.

Faulty starter motor – The starter motor is used to crank the engine, allowing the car to start. Any problems with the starter motor or the starter motor solenoid can prevent the engine from cranking and cause the clicking noise when trying to start the engine.

Faulty starter motor solenoid – if the starter motor solenoid won’t hold in properly it may bounce on its electrical contacts, causing a loud clicking noise when trying to start your car engine.

Alternator problems – The alternator provides electrical power to your car’s battery. If the alternator is not working properly, it will cause your battery to go flat quickly. If your car’s battery goes flat shortly after jumpstarting, the alternator could be the source of the problem.

Faulty Ignition Switch – A faulty ignition switch can cause intermittent or complete loss of power to the starting system. This can result in a clicking noise when you turn the key. If you suspect an issue with the ignition switch, it’s best to have it diagnosed and replaced by a professional.

Starter Relay Issues – The starter relay controls the electrical current flow to the starter motor. If the relay is faulty or not functioning properly, it can cause a clicking sound when starting the car. A professional diagnosis can help determine if the relay needs replacement.


Extending the life of your battery and charging system

To extend the life of your battery and charging system, you can follow these maintenance tips:

  • Regular Battery Inspection: Routinely inspect your battery for signs of damage, corrosion, or loose connections. Check the battery terminals and clean off any corrosion with a mixture of baking soda and water. Ensure the terminals are securely tightened to maintain proper electrical connections.
  • Keep the Battery Clean: Keep the battery and its surroundings clean and free from dirt, debris, and moisture. Regularly wipe the battery case to prevent dirt or moisture buildup that could lead to corrosion or electrical issues.
  • Avoid Battery Drain: Avoid leaving lights, accessories, or electronics on when the engine is not running, as this can drain the battery. Turn off headlights, interior lights, and other electrical components when the vehicle is parked.
