Avital's best 1-way security and remote start system will start your car with the push of a button from up to 1,500 feet away, and help protect it from thieves and vandals with the included Zone-2 Impact sensor (which detects blows or impacts to the vehicle), the Revenger siren which will loudly alert you when the impact sensor has triggered - and the Fault-proof starter interrupt, which is designed to prevent "hot-wiring" your vehicle.
