KEYLESSBLOCK is a product developed to protect your car from the latest theft method, "RELAY ATTACKS". After locking with the smart key, the vehicle will no longer receive the smart key's signal, shutting out theft methods that use the smart key's signal (relay attacks, key emulators). The smart key's unlock button is functional, and it is possible to authenticate by pairing a smartphone or using the key fob. Similar to IGLA, this KeylessBlock operates by utilizing the vehicle's digital communication (CAN-BUS), thus causing no damage to the vehicle's wiring. - Product Name: Keyless Block Pro Plus - Accessories: 2 remote controls, wiring - Manual: Instruction manual, sticker
