I'm sorry to say, there is no work around it. You can bypass the door module but when you apply the brakes the cars shut off. I have tried that by taping the door sensor on the body and when I applied the brakes, car shuts off... Toyota is too smart in not wanting to risk and law suits or liability of that.
Don't know why they don't have remote start for IS when all the other ones have them...
