Life Hack: Use Tin Foil as a Key Fob Guard
Technology seeks to simplify our lives, making everyday tasks just a little easier. Take the keyless car entry, for example. Many key fobs allow us to unlock our cars and turn on our ignitions from a distance.
However, as technology advances, so do the tactics thieves use to capitalize on it.
Now, it may be possible for car thieves to intercept the signal from your key fob using a special receiver called a “relay attack.”
Luckily, there’s a simple life hack that can prevent the signal from being transmitted — simply wrap your key fob in tin foil.
Although it may not be ideal, tin foil is the least expensive key fob guard on the market, as you can probably find some in your kitchen pantry. Made of aluminum, tin foil can help to block or shield radio frequency waves.
Tin foil can also be used to safeguard other technology, including your cell phone or tablet.
Not into the idea of wrapping your keys up like a baked potato? We get it.
You can also purchase special bags that are lined with a metallic material to prevent signals from going in or out.
