I have 98 SC300 which has 3-buttons.
I just lost my only key that has chip and the fob. The only key I have is the valet key which does not have any fob. It can only open the doors and turns on the car. I know the key gotta have a chip to turn on the car. So maybe the key have the chip?
I talked to lexus, they told me that since I dont have the chip anymore, they have to replace the whole system or something which cost thousands of dollars.
Is that true?
Is there any alternative way to program the chip?

I only have a valet key, it does start the car. So maybe 98+ do have smart chip? Does it mean valet key have smart chip that can program to the fob? Or am I still screwed?

In my case, this is what I did three weeks ago for my 1999 SC400. I bought a "long" blank key off ebay with the "empty fob case" for under $ 15. I then prepay/sent the blank to Sewell Lexus in Dallas for them to cut the key with proof of who I am and VIN #/Insurance Card. They sent the cut key back to me, and I can use the new key to manually unlock the door and start the car. There are NO chip on the key and I did not press any buttons on my working key fob. Works like a champ because I really needed a spare in case I lost the original.

Valet key can only unlock both doors and start the car. Unfortunately you cannot use the valet key to program a master key. Yes the valet key has the smart chip imbedded inside the gray key head, this allows the immobilizer to work.
