key

So I've got a late model (1996) 180sx, and ive purchased a different ignition barrel for the sole reason of it came with and works with a cool rare oem key. Problem is that I've noticed that the ignition barrel in my car has a white module right below the key hole with two wires coming out of it...

as titled, i need skyline r32 keys, ignition barrel, door lock etc. basically the bits you need after you snapped your one and only key. need them urgently... thanks
