Is there a way to protect Toyota/Lexus vehicles from CAN inverters (CAN attackers)?

Yes, there is.
However, it’s important not to rely on just one countermeasure, but to combine multiple measures based on the model and how the vehicle is used.

A CAN attacker is a method that targets door unlocking and starting by misusing the vehicle’s communications.
As a result, measures that only address the radio signal of the factory key may not be enough in some cases, so you need to focus on measures that stop unauthorized starting.

At LOGON, as an anti-theft solution for Toyota/Lexus vehicles, we organize and provide guidance by model—for example, the following types of measures.

• The security unit that suppresses unauthorized starting
• Alarm measures that notify you of anomalies
• Supplemental measures around keyless entry and smart access
• Additional measures tailored to your parking environment and usage

What’s important isn’t simply adding stronger equipment, but carefully addressing the points that are most likely to be targeted while maintaining a balance with everyday usability.
In particular, for vehicles such as the Land Cruiser, Alphard, Vellfire, and Lexus SUVs, the approach changes a bit from model to model.

Even if you’re unsure how much protection your own car needs, that’s okay.
We can organize the recommendations according to your vehicle model, storage environment, and preferences—so please consult us while first checking the security plan by model.
