The ignition switch is a crucial component in your 2004 Honda Accord, responsible for starting the engine and powering various electrical systems. Understanding its function, symptoms of failure, replacement process, and purchasing options can help ensure your vehicle operates smoothly.

If you experience these issues, it may indicate that your ignition switch is failing and needs replacement.
