This is the Author OBD Blocker. It is designed for protecting and "blocking" the use of your vehicle's OBD-II port (on board diagnostic port). The OBD-II port is how many thieves access the data bus systems of your vehicle, in order to program new key fobs, or control the vehicle to start without the vehicle key or key fob. Blocking the OBD-II port significantly increases and improves, the security of your vehicle. Key Features and Benefits Active Digital Protection: Unlike physical covers, this device digitally breaks the diagnostic line, making the OBD port inactive unless the authorized dongle is connected. Automatic Blocking: The system automatically re-activates the block 20 seconds after the authorized dongle is removed. Universal Compatibility: Designed to fit most vehicle makes and models with an OBD2 port. Anti-Theft Security: Protects against advanced theft methods, including unauthorized key reprogramming and disabling of standard alarm systems. Invisible Installation: The device is installed behind the dashboard, making it stealthy. How It Works A digital relay is installed in the car's diagnostic circuit. If the authorized personal dongle is not inserted, the Author OBD Block prevents any tools from communicating with the car's computer. When authorized maintenance is required, inserting the dongle allows diagnostics to proceed.
