New Threats to Vehicle Hijacking in South Africa: The Rise of Signal Jamming

　　South Africa has been a global hotspot for car hijacking and theft, with criminals using a variety of means to threaten car owners and drivers. https://www.silencejammer.com/ In recent years, a new criminal method has been spreading rapidly, which is the use of signal jamming technology to prevent car owners from locking their vehicles normally, resulting in the theft of vehicles and valuables. https://www.silencejammer.com/mobile-jammer-cell-phone-blocker Charnel Hattingh of Fidelity Services Group said that people who have experienced remote jamming will feel helpless and frustrated, and this new criminal method has made the security situation in South Africa worse. https://www.silencejammer.com/gps-jammer-blocker-car-signal

　　What is signal jamming?

　　A signal jammer is a device that can emit interference signals to disrupt the transmission of radio waves or other electronic signals. It can prevent specific devices, such as remote control locks, GPS trackers and smartphones, from receiving or sending signals. This means that criminals only need to use signal jammers to block the vehicle's locking signal when you lock your car, so as to easily open the car door and steal valuables in the car. https://www.silencejammer.com/wifi-jammer-bluetooth-blocker-device

　　Ryno Schutte of Pro-Active noted that the use of signal jammers is increasing rapidly in South Africa, especially in the transport sector, where criminals are hijacking goods and vehicles by jamming GPS and GSM signals. The devices are small and portable, and very simple to use, so they are widely used in various crimes, especially for vehicle theft and hijacking.

　　How signal jammers work

　　The core principle of signal jammers is to interfere with the communication between the vehicle and the key by emitting radio waves at the same frequency as the vehicle's remote lock signal. When the owner presses the remote lock button, the key will emit a lock signal, and the signal jammer prevents this signal from reaching the vehicle by emitting a strong jamming wave, making the owner mistakenly believe that the vehicle is locked, but in fact the door is still unlocked. Criminals can easily open the door and steal the contents of the car after the owner leaves.

　　This method of crime has spread rapidly, especially in cities such as Johannesburg, and has become a new means of stealing vehicles and their contents. Criminals use portable signal jammers to easily commit crimes in busy shopping malls, parking lots and other places, and car owners often do not find out that the items in the car have been looted until they return to their cars.

　　The impact of signal jamming on South African society

　　In recent years, signal jamming crimes in South Africa have shown an upward trend year by year, especially in the transportation industry and personal vehicles. Schutte pointed out that criminals can easily prevent vehicles from being tracked and locked by illegally purchasing GSM and GPS jammers, and can even operate vehicles at will after the vehicle's GPS tracker is disabled. The abuse of this technology has had a serious impact on South Africa's security and economy.

　　Increase in theft cases

　　The number of thefts using signal jammers is increasing, especially in busy parking lots in large cities. Criminals target car owners who rely on remote control to lock their cars and steal by jamming their locking signals. According to statistics, in Johannesburg alone, the number of vehicle thefts related to signal jamming increases by more than 15% each year.
