When I had a Tundra I installed the Toyota factory remote start and it took some time but was pretty easy. I was thrilled to see a similar kit for the Landcruiser but then found the directions that talk about Techstream programming. I am not sure if anyone else has installed this and can comment or if the techstream is not that bad to do? I Have used the 12volt solutions one on my Tacoma and has grown third of the endless "key not found" errors after installing it so would like the factory one ad really don't want to pay a dealer to install it if I can. Thanks in advance.
