Introduction:
Car jamming has become a growing concern in South Africa, posing a significant threat to vehicle security. As technology evolves, so do the methods employed by criminals, making it crucial for car owners to stay informed about potential risks and adopt preventive measures. This article explores the dangers of car jamming in South Africa, with a specific focus on keyless locking systems, and provides valuable insights on how to protect your vehicle effectively.

Understanding Car Jamming:
Car jamming, also known as remote jamming or signal interference, involves criminals intercepting the signals between a car remote and the vehicle itself. By using electronic devices, perpetrators can prevent the vehicle from locking properly, leaving it vulnerable to theft. This method is particularly prevalent in crowded places such as shopping malls, parking lots, and public events where car owners may not notice the attempted interference.
The Risks of Keyless Locking Systems:
Keyless entry systems have gained popularity for their convenience, allowing users to lock and unlock their cars without physically inserting a key. However, this convenience comes with risks, as criminals have adapted their techniques to exploit vulnerabilities in these systems. Keyless entry systems use radio frequency signals, and if intercepted, criminals can gain unauthorised access to the vehicle.

Operational Insight into Remote Jamming:
The widespread use of similar frequencies in vehicle and gate remotes makes it easier for criminals to interfere with signals, leaving drivers under the false impression that their vehicles are securely locked. These incidents often occur outside shopping centers, airports, or other areas of interest, emphasising the need for heightened vigilance in such locations.
The Danger of Vehicle Theft:
Car jamming not only puts your vehicle at risk of theft but also exposes you to potential harm. Stolen vehicles are often used in other criminal activities, and the recovery process can be time-consuming and financially burdensome. It’s essential to recognise the severity of the issue and take proactive steps to protect your investment and ensure personal safety.
Practical Tips for Vehicle Security:
- Double-Check Locking:
Ensure your vehicle is properly locked by testing the door after activating the alarm. Drive away immediately if any issues arise.
(Some vehicles wil automatically unlock again as soon as you touch the handle, so this is not a perfect solution) - Stay Vigilant:
Be aware of your surroundings, especially in parking areas, and
lookout for suspicious individuals. - Signal Blockers and Faraday Bags:
Invest in signal blockers or Faraday bags designed to block radio frequency signals. Placing your key fob in a Faraday bag when not in use can prevent criminals from intercepting the signals and protect your vehicle from potential jamming. - Confirmation Sounds:
Listen for the distinct sound of your car locking and wait for the lights to flash before walking away. - Strategic Parking:
Park close to shopping center entrances, where there is increased visibility and foot traffic. Report any suspicious activity to security. - Proactive Measures:
Report suspicious individuals to security personnel or relocate your vehicle to a safer location. - Research:
Some manufacturers have built in contingency systems to deactivate the keyless function, thus reducing the potential of your signal being cloned and your car being stolen.

By staying informed, ensuring insurance coverage, and implementing these practical tips, South African vehicle owners can safeguard their vehicles and belongings from the growing threat of remote jamming.
