It’s an open fact that a home built device which is able to capture signals from the Smartphone app to track, unlock, and remote-start a car which is registered on the app.
The most recent model takes advantage of a quite old vulnerability in car keyless entry systems. Generally, the remote used for rolling codes to communicate with the car means that the remote transmits a different coded signal each time the user pushes the button. This is intended to stop the unwanted people from stealing the remote’s code to generate an imitation remote. In general remote garage door openers functions on a similar theory.
However, most automakers don’t set a termination date for the codes used earlier. It’s a safety precaution that a single code can’t be used twice, if a code never reaches the car it’s still valid for the use.
That is where the modern device comes in. The wallet-sized device can be hidden on or beneath the intended car. When the owner pushes the remote unlock button, the device detects the remote signal and jams it, stops the car from hearing the signal. Given that the car has not unlocked, the owner press on the release button the second time. The device records the second code, and transmits the initial code to the car.
Here the car is unlocked, but the device remembers the stolen second code, which does not reach the car at all. It really is the need of the hour in the unsafe world.
