Master Key For 1997 Sc300

[raymsixsix]

Good morning! I have a '97 SC300 and when I bought the car, it came only with the valet key and remote. I tried ordering a master key from Sewell Lexus using the VIN. They cut and shipped the key, yet it did not work. The new key wasn't even remotely similar to my valet key. I called Sewell and they said that it sounded like the locks had been changed on my car, yet I didn't receive a key code with the books of the car. I called Lexus of Tampa Bay and was told that Lexus doesn't make the key for my car any more and it has a transponder embedded in it. He went on to tell me that my car uses a master key with the three buttons on it. I find that hard to believe, as what I'm using now is a key with a separate Lexus remote. My question, gang, is how do I get a Master key cut for my car, given the locks don't match the VIN?

Thanks
