I'm doing a lot of research, and I want to get the opinion of others... I currently only have a valet key and am getting annoyed/paranoid about not having a master or another key. I have been looking around, and I have heard a lot about Techstream. I believe with Techstream I can wipe all the existing keys off the ECU and program new wireless keys. My biggest worry is this. Because I only have the valet key to help with programming, I do not know if it'll even be possible considering that the key needs specific button configurations on a current remote to work. Has anybody attempted this, or am I going to be the guinea pig?
