hey, it is not the door... it depends where you put the safety button on.... my was on pressed by the hood, if the hood is open, it won't work...
as soon as you have ur car put in netual gear, nothing happens...
but be careful of ur friends or mechanic... i recommend u turn it off whenver you are not driving it..
my brother in Hong Kong just crashed his Civic
coz he didn't know my father drove in at night, and my dad left it in 1st gear, then my brother started it before he goes to his car, it hits the wall ... lol.... then it cost him around 1000 CAD to fix it
