Can anybody tell me a more economical way of obtaining another RX300 spare key without spending a fortune. I just bought a used RX300 SUV and the previous owner or the dealership didn't have the key code and the car only came with one master key and I was told by the Lexus dealership that it'll cost about $250 plus $50 for programming the chip on my Lexus. Is there a way around this. There must be a procedure to program a Lexus RX300 key to work with my Lexus without spending a fortune.
