Car won't start and just clicks? Battery or starter

Rapid clicking when you turn the key usually means the battery is too weak to spin the starter; a single loud click with no crank more often points to the starter or its connections. A quick battery test separates the two.

Is it safe to drive?

A no-start is an inconvenience, not a driving hazard — but don't keep cranking, which can overheat the starter. Test the battery first.

What to check first

  • Check for dim/no dashboard lights — a sign of a dead or weak battery.
  • Clean and tighten the battery terminals; corrosion causes exactly this.
  • Try a jump start — if it fires right up, suspect the battery or charging system.
  • If the battery is good and it still single-clicks, suspect the starter or its solenoid.
