I have keyless entry, and would like to "stash" a spare key somewhere on the frame in case I loose my smart key while hiking or hunting. Does anyone know of a way to have a key cut for the door with a chip in it that doesn't "transmit" all of the time? This key could be held to the start button once you were in the car to start it in case of emergency.. I could purchase a spare smart key and turn it off or take the battery out, but that is an expensive proposition.
