Why Does the Key Turning Produce a Clicking Sound But Fail to Start the Engine?

[MacMorgan]

The common reasons for hearing a clicking sound when turning the key but failing to start the engine are: 1. The clicking sound is the noise from the relay or the starter motor working, indicating that the starter has responded but lacks the power to turn the flywheel, resulting in failure to start; 2. The battery may be low on charge, which can happen if the headlights were left on when parking or too many external devices were connected; 3. Insufficient voltage can also cause the engine to fail to start with a clicking sound, often due to an old battery that has degraded over time and holds less charge; 4. The gear not being in the P position when starting. It is important to contact a 4S shop promptly to diagnose and fix the specific issue.
