Cryptalloy Silverstone is a protective case for a car remote control with an electronic locking and starting system that allows keyless opening and starting of the car (KESSY - Keyless Entry, Start and exit System). The walls of the entire case are provided with double shielding made of Cryptalloy material, which shields all frequency bands used for reading data. The case will fit electronic keys from most car manufacturers (see case dimensions below). By placing the keys in a closed case, you will prevent their unauthorized reading from a distance and also prevent car theft using RSA (Relay-Station-Attacks or signal amplification attacks), which are occurring more and more frequently. This is an important security tool for all owners of cars with keyless unlocking.

We recommend for all owners of cars that have a Keyless system, thefts are already occurring in the Czech Republic, see. for example this article and also this.
