However, as soon as the first lucky owners of cars equipped with KeyLess-Go began using their cars, one unfortunate thing became clear: the system was vulnerable. And attackers with special relay equipment can fake a “conversation” between the car and the key and take possession of an expensive vehicle.
Until now, manufacturers have not found a way to reliably protect the communication channel between the key and the car, so the “Kulibins” got down to business. Car enthusiasts have discovered that a simple piece of foil shields repeater requests and protects the key from virtual attempts by fraudsters.
So, a rich man who carefully wraps the key to his Mercedes in foil may seem funny, but he does not have to tear out his hair, styled at a hairdresser, upon discovering that the car has been stolen !
