Mate you will never communicate with a holden commodore with chinese key programmers. I use either a carmen scan or snapon modis scan tool to program commodore keys. I am sure that others on here also use x431 launch tools to do it as well. not sure if the launch out of china will do commodores but someone on here will have one and could tell you. I dont have a t300 so couldnt tell you about the camry.
