CAN-Bus shields/blockers are available for certain models that are frequently stolen using the CAN-Bus attack method. The blockers are designed to help protect vulnerable access points that thieves use to tap into your car’s CAN-Bus system. These are a good addition to your security plan if this type of theft is common for your vehicle, but since it only helps fight one of several methods of “car hacking”, it should be part of your layered defense, not your only defense. These devices do not protect against theft methods like relay attacks and key programming theft.
Toyota/Lexus CAN Bus Anti-Theft Shield by Miller CAT


When it comes to Can BUS injection car theft, one of the most common ways for thieves to access the vehicle’s Can BUS system is through the headlight wires in vehicles equipped with adaptive headlight technology. This is one of the most common ways that modern Toyota and Lexus vehicle’s are stolen and many recovered vehicles have a damaged headlight from this. The CAN Bus Anti-Theft Shield by Miller CAT adds a physical barrier to block this common point of access to the system. While this may not help protect all types of theft, it is a fairly low cost security measure against one of, if not the most, common theft method for these cars. Be sure to read our late model car theft prevention article for more ways to reduce your risk of car theft.

Honda Radar Shield by Miller CAT


One common way that thieves are able to access the Can Bus system on late-model Hondas is through the front radar distance sensor that is used for features like Adaptive Cruise Control and the Collision Mitigation Braking System. It is located behind the Honda “H” emblem on the front of the car and is one of the easiest options for a thief to inject unlock and start commands into your Honda’s Can BUS system. The Honda Radar Shield physically blocks this access point offering an affordable layer of defense against this specific type of attack on late model Accords, CRVs, and Pilots. Remember, this only provides protection against Can BUS injection theft, and not other common methods like relay attacks, and making new keys, so be sure to read our full article on Late Model Honda Theft Prevention, and make this a part, but not all of your layered defense strategy.
