that is possible with the elimination of your key. you would just need something has has a big RF signal to trigger something to allow ur car to start. Although the new infinities are nice, the keyfobs that they use such as smartkey makes it a biatch to install remote starts (when it has push start)

there is no other way to move ur ignition wires, they are there for a reason, to make them impossible to hotwire, u can put them across a metal loom then no1 can cut that. its not easy to cut with a side cutter.
