truck push-button start? careful where you set your 'key'

I can't speak for all these other vehicles but my Exploder complains if the key is outside of the drivers seat radius more than about 3', just beyond the door handle

This is completely different from simply unlocking it where I can get easily 150' range to unlock and remote start.

And Yes, you can wrap it in foil and totally isolate it from the car receiver. I used to hide a Keyfob in the car and it never knew it was there
