Key fob signals can be copied and amplified by criminals. Law enforcement and the National Insurance Crime Bureau (NICB) in the United States have documented this. Imagine your key fob as a music player.
According to the CEO of GuardKnox Cyber Technologies Ltd, Moshe Shlisel, a business that develops cybersecurity technologies and patents to secure critical systems and automobiles, "Once thieves know the exact tune, they may play it and steal your car," he stated.
Carjackers replicate the owner's parking lot signal and use it to steal their vehicle once the owner has entered their business or shop. Alternatively, they may wait until the next day and steal the vehicle.
The signal is amplified by a separate device when it is in a home or apartment. However, it is possible to take stuff from inside the vehicle even though it cannot be started using the gadget.
