I have key-less go in my new Tacoma. I'm hoping Toyota came up with the solution. My truck knows the whether my key fob is inside or outside the cab as there are certain features ie; you can't lock the doors with the key fob inside. If you use the remote start, the engine stops as soon as the doors are unlocked and the key fob must be present to start it again. With this recognition ability one would think they could code it properly. An additional RFID chip with a close proximity distance limit should do?
