Wiring and Finding Parts

I am not sure I follow what a key surround is. My car has a factory dash ignition switch. I have a dash in the car but most of the relays were picked out. Ignition switch was picked as well. I do have the wiring for the ignition light in the harness and the bulb was clearly cut off from the wire.
As I recall, there was a slot in the chromed pot metal(?) housing where the light shined down onto the ignition switch. I never pulled it out so don't know the details. Nice feature.
