Add a remote start to a Subaru by installing a bi-directional remote start system on the car. Once the system is installed, the car owner has to simply press the start button twice on the hand-held remote control to start the car.
It is a prerequisite for the car and the remote control to be within the range of 400 feet for the remote start system to work. When the start button is pressed twice by the car owner, the horn chirps twice, followed by the flashing of the parking lights to indicate the triggering of the remote start system. The vehicle confirms receiving the signal by signaling the hand-held remote to flash twice to affirm that the car has started, according to Subaru.
