If it cuts out with the key it will with the button. As far as the car is concerned, it can't differentiate between the button and the key. I think most cars will cut off most accessories (lights, radio, climate control) so almost all power can be dedicated to the starter. Do you have some kind of high-power fancy car audio system?

I used two SPDT relays because they were cheaper than one DPDT relay with the appropriate current rating.
