i know its features,if u keep ignition on after turning off the car then your car cant be started without the card n if u dont do this then any1 can start the car n it will shutdown after few second n wont start without the car,but that system is located right under steering to the left side where u show the card n sensor reads it,if they hide it somewhere then that would take more time
i already have steelmate 2 way security system which is even more expensive than this one,but i think for that you just need to remove the wires from the battery n it would be dead
