Yeah, this is definitely something of interest for me. I know even the latest Toyota cars have the 5x's key in 6 door close trick. I'm theorizing that it could still be a subaru security system fashioned to look like a Toyota. I have no one to blame but myself for this, but I just can't stomach the fact that I have to pay that much for something so little. I'm very stubborn, and I will find a way. Even if it means buying the OBD programming device myself. Then start offering for cheaper prices in the area to make up for the loss.
I did that learning Paintless Dent Repair as well. Been taking out my own dents and other peoples dents for a while now. I can always expand my freelance services.
As soon as I find a way, I'll create a guide on how to do it. I know i'm not on here a lot but I try to contribute when I can.
