The CAN BUS FIREWALL is possibly the first manufactured immobilization system that communicates bidirectionally with up to two CAN bus data systems and one LIN. This digital immobilization system helps protect your car from theft, key cloning, Keyless range extension, vehicle key learning, key code hacking from the vehicle key, and even theft of the owner's key. Only towing the car is possible because a thief will never be able to drive your car. The new WFS400-LIN is the third generation of CAN BUS FIREWALL protection and is a greatly improved version of its predecessor in many ways and in its functionality.

The WFS400-LIN no longer requires additional remote controls, transmitters, or driver program cards. No flashing LEDs or keyboards can lead to the location of the device installation in your vehicle. Additionally, the electronics are extremely compact, so the installation can be hidden within the vehicle's wiring. The system automatically arms when the ignition is deactivated.
