Thanks for everyone's info. I thought I would let you know that I bought the car at a discount because of the missing master key. I then got a free ECU and install at the Lexus dealer. The only cost was $250 for the actual key. Apparently you do get one free ECU if the car is still under warranty.

Thanks for the information. I think I'll just offer $1,300 less for the car and use the money to get the new ecu.

I am looking at buying at 2001 GS300. The problem is that it only has the valet key. I am buying from a non-Lexus dealer. I called on Lexus dealer and was told I could get a master key and have it programmed for about $250. I called another and was told I would have to replace the car's computer for around $1300. Who is correct?
