i'm not looking to get rid of the key all together... just add a little more flair to the car. if you were going to wire a switch where the hazard is, i'd use a piezo switch. (expensive, but effective for ignitions)
the more i think about it, the more i don't want to do it. so far all my mods are removable, when the event of my graduation comes around, i won't be able to spend any more on this. and something like that is just asking for problems....
