Thieves use relay attacks to boost a key fob's signal from inside your home and steal your car.
Wrapping the fob in aluminum foil blocks those signals if done right with multiple layers.
Better options like signal-blocking pouches and smart parking add stronger protection.

Drivers are wrapping their smart car keys in aluminum foil to shield them from relay attacks, where crooks amplify the key's signal to unlock and drive off with vehicles.

It matters because car thefts are rising with sneaky tech, and simple fixes can protect most owners.
