I bought my RX 350 while I was l living in Hawaii in 2008. I moved back to the madland, aka mainland and tried to get a replacement ignition key made but no one can program it using standard directions. Of course the dealer can but that's over $400 here. My question is, do cars made in Japan have a different programing sequence than those assembled somewhere else? Help, my remaining key is about to fall apart.
