What Is an Ignition Switch and Why Is It Important?
The ignition switch is a critical component that connects your car’s battery to essential systems like the starter motor and fuel pump. When you turn the key or press the start button, the ignition switch sends power to start the engine.

Insert the key and gently wiggle it while turning. Worn internal contacts sometimes reconnect briefly, allowing the engine to start.

A worn key can prevent proper ignition contact. Using a spare key may solve the issue temporarily.

If the steering wheel lock is engaged, gently turn the wheel left and right while turning the key.

For manual transmission vehicles, push-starting may work if the ignition switch still allows minimal power flow.
