KEYLESS BLOCK specializes in "not letting the doors be opened in the first place." Against methods that try to unlock illicitly—relay attacks, CAN invaders, key emulators—it protects by preventing the door unlock itself from succeeding.
The look and everyday convenience barely change, and you keep using your smart key as before. Combined with a start-prevention type (such as IGLA), it forms a two-stage "won't-open + won't-move" defense for extra peace of mind. Feel free to ask us whether your car is supported.
