Key code Registration has failed with teachstream and 2007 Lexus GS450h
Hi, I bought in ebay an unlock smart key for my 2007 European Lexus GS450h. With techstream i go to "smart code registration" and i follow all steps, But in the last step, when say "Place the key in the P-Seat" i get error: "key code registration has failed" Possible Causes of the failure:
-Maximun number of keys already registered (No because in number of avalaible spaces for new codes says "5") - Key has already been registered (No, the key is unlocked) -Turn the engine/power switch OFF (NO, it is ON) - Vehicle battery voltaje is low (No, vehicle battery is ok) - Key issue/low battery voltage (No, battery is new) -Additonal keys present in the vehicle (No, no two or more keys into the vehicle)
I don´t understand, what is the problem?
