Watson Streetwork's sells some neet ignition cut off switches that can be installed and hidden in the car. I installed my switch inside the car. Its a small button switch that can be installed any were you want even under the upholstery. They sell another type that works with a fob that activates the switch. Also I think they have one that works with a credit card kind of gizmo that you keep in your wallet and when you and the wallet get close enuff to your car, it enables the ignition (no switches to worry about)
