Push To Start Buttons

If you install a button to start your car will it still start if you turn the key all the way or does the button override this?

if u choose to do so....I like to do a "starter enable" circuit on the push start buttons that prevents it from cranking the engine if the key isn't in the the cylinder.  Some cars have a nice key sense that can control a relay directly.  another alternative is to use ignition to energize a relay that only allows the push start to work when the key is in the run position.
