Redsteve, MAN, you RULE! You just saved the day! I couldn't believe this could work, but... I unlocked the whole board-computer just a couple of minutes ago! THANK YOU VERY MUCH! I spent 3 days searching the web for the solution of this problem with no luck. I tried to go to a local Lexus dealer - no luck too. They said they needed a code that I didn't have or they could unlock it for about $200 asking for the code in Brussel. Wow! I came home, tried to look over the net again and TA-DAA! I got the solution, YOUR SOLUTION and man, it worked! You are great!
