Brand New OEM Honda / Acura NSX Ignition Starter. A common issue with first generation NSXs is that the ignition starter fails to run, which can happen due to a failed ignition motor or the actual switch inside. Sometimes a quick replacement of the key cylinder switch can fix the issue, but if not, then a new assembly is required. With the new assembly, it does come with a new set of keys, as well as the required key cylinders for the doors and trunk to match the new keys. Please be aware that when ordering a new assembly that you will need to change your NSX’s door and trunk’s cylinder as a safety measure.
