A device or system that disables a vehicle’s electrical system, preventing it from being started, can be a highly effective anti-theft measure. For example, cutting off power to the fuel pump or ignition system renders the vehicle immobile, even if a thief manages to gain entry.
The value of such a system lies in its ability to deter theft, offering a relatively inexpensive layer of security compared to advanced tracking systems. Historically, these systems have been a popular choice for vehicle owners seeking a simple and reliable way to safeguard their property against unauthorized use.
