depends how you want it installed.. I have no safety features removed...
but I have to do a process BEFORE I TURN OFF THE CAR.. to have it set for the next time.
come to a stop.. make sure in neutral.. foot on brake.. open door.. foot still on brake.. press remote start button... let foot off brake.. remove key.. put key in pocket.. close door.. car still running.. press lock button on key fob.... then press remote start button.. car turns off, doors are locked.
If after that, at any point, someone opens the door or even UNLOCKS the car, the remote start is disabled until the above procedure is done again.
no way to have car in gear when getting out of the vehicle.
Most (I thought all) manual cars have a neutral switch in the clutch that has to be defeated for remote starts to work.
