Let's see how the CanLock alarm works on an Audi Q5: unlike traditional alarm systems, CanLock does not rely on radio signals but acts directly on the vehicle's electronic system, utilizing the CAN bus network. It intervenes on the digital signal that allows the car to start, blocking the engine and making it impossible to start the vehicle.

It is resistant to common theft methods such as "relay attack," "code grabber," key duplication, and the use of OBD readers. We see that the YouTuber, who tries to enter the vehicle, attempts to start it without success; the gears do not engage, everything is locked.

To unlock it, you need the specific key fob, which disarms the alarm and allows you to start the car.
