Here is what I came to last night. I was bored so I cut up a key and a set of ***** and here is the result. I really like this as it locks stock, can be reverted back to factory just by pulling it out and by making it only a key, it can't be used to start the car unless the factory key is used or the RFID tag is right next to the sensor. I'm having distance issues right now and need to get a more sensitive antenna but aside from that, this might end up just being something I can make from existing components. This probably won't make it cheaper, maybe even more expensive but I won't need it to be a really large group buy deal so we'll see what everyone thinks and what my total costs are when I have it functioning exactly how it's supposed to. I wished this f*ck*ng marvel of a phone Apple made actually could record video without having to spend $30 so for now, pictures will have to do.
