If turning the key no longer brings your car to life reliably, the Standard Ignition Starter Switch US-546 is a direct-fit Honda Civic switch replacement for the 2001-2005 Honda Civic and the 2002-2004 Acura RSX. The ignition key operates this electrical switch, which sends power to the vehicle's ignition, accessory and starting circuits as the key moves through each position. See the "Vehicles it fits" section for engine details.
Signs this part may need replacing include an engine that does not crank when the key is turned, intermittent loss of power to the dash or accessories, or stalling while driving. Other electrical or starting components can cause the same symptoms, so diagnose the cause before you replace the switch. If a failed ignition switch is the problem, the US-546 replaces it.
