How dumb do you have to be to pay 400 dollars to have a microchip implanted in your body just so you don't need to have your keys with you to start your car? Also if it works at all like any car I've been around where the key is wireless, sure the door will unlock when you go to open it with the key nearby, but he still will need the key with him to lock the car unless he wants to have to press the button inside the car to lock it everytime. If that is the case which I assume it likely is, this is literally less convenient than just having normal keys, on top of that you now have a microchip inside you that could be collecting and storing who knows what type of data, and is likely hackable. Good job buddy!
