push button

I thought about it a couple times, cant say I have seen it done. I know they have the kits for the 05+ cars

one way... interrupt the starter wire in the column with a relay and put a push button somewhere. you would have to have keys in the ignition.

another way.. purchase a remote start. use the "acvitavtion input" wire. set that wire to 1 or 2 Negative pulses, then itll start the car, no key in ignition. easiest way of doing it i think.
