German Car Owners Use Microwaves to Foil Relay Theft
Car owners in Germany are discovering an innovative yet practical way to safeguard their keyless keys from relay theft. By storing their keys inside microwave ovens, they're transforming these common kitchen appliances into makeshift Faraday cages, obstructing electromagnetic signals and making relay attacks more challenging.
This DIY security technique has caught on among car enthusiasts, especially those driving popular models like the VW Golf, VW T-Roc, and VW Tiguan, which were top sellers in 2024. It's an affordable solution, utilizing a standard household appliance to bolster security. Nevertheless, it's essential to recognize that not all microwaves provide equal protection, and signal leaks can occur through gaps or the door lock.
While this method can help deter relay theft, it's not ideal for daily use. Keeping keys away from doors and windows, and opting for vehicles with advanced key technology, also play a significant role in enhancing security. Furthermore, improper usage of microwaves can pose safety hazards and potentially damage the key or the device.
In conclusion, employing a microwave oven as a Faraday cage is a simple and budget-friendly way to safeguard keyless keys from relay theft. However, it's not a perfect solution and should be employed judiciously, considering the potential risks and impracticalities for daily use. Car owners are advised to combine this method with other security measures for optimal protection.
