The simple gesture that can make the difference
This is the most surprising —and yet effective—home solution: wrapping your keys in aluminum foil . This metal acts as a barrier against waves, preventing the signal from being picked up from a distance. It’s not very aesthetic, but it’s a good backup solution at home, especially at night, as recommended by Holly Hubert, a former FBI agent, as relayed by the British media The Telegraph
Other easy-to-implement alternatives
- Store your keys away from entrances : avoid leaving them in a cup near the door. Instead, keep them in a closed drawer or cupboard.
- Use a metal box : it acts as a natural shield. A simple metal tea caddy can be enough.
- Invest in an anti-radiation pouch : Designed specifically to block radio signals, it protects your keys while keeping them accessible.
