i just bought a 2000 RX with only the valet key. I called the Lexus dealer and they said you can't cut a master from a valet key. They also said that I might need to have the entire security system replaced but that Lexus has a program that might pay for this.
Does anyone know anything about this and what the criteria might be?
A side note, for all the service records this owner kept, how he managed to only have the valet key perplexes me.
