Thanks for the reply...
I did some investigation into the situation and you are right, YOU MUST HAVE A MASTER KEY TO PROGRAM ANY OTHER KEY.
That doesn't mean you can't program the remote operating function of the key, you just can't program the cranking code via a valet key(the dark grey key)
I was confused because the instructions state to enter the vehicle with a pre-programmed working key. To me the valet key was this because it does everything to the RX except for opening the glovebox.
Anyway, I called Lexus and they are ordering me a computer. I don't think I will have to pay for the computer, just the labor involved. I am hoping for the best.
Thanks again,
Eric
