Hi, I am a new member in Melbourne with a MY07 GT SpecB wagon. I need to get a new replacement remote key and I just about died when the dealer told me the blank was over $300

Does anyone know of a cheaper alternative?
In the past, for different vehicles, I have purchased from an online shop, but I can't seem to find one who does the integrated Subaru remote key?
Open to ideas...
Cheers, Melangus47
