\"foil<\/a>Sigh.\u00a0 More proof mean people suck.\u00a0 So here is the story.\u00a0 Thieves are using signal power amplifiers to extend your cars reach to your key fob.\u00a0 The way it works normally is when you are a few feet from your car, the car’s remote sensing system detects its your key fob and unlocks itself.\u00a0 Well if you can amplify that query signal the car is sending out, you can get the car to ‘see’ you key fob up to 100′ away.\u00a0 Perhaps more.\u00a0 So if you keep your keys in your house within 100′ of the car, the thief just needs to walk up to your car, turn on the amp and try the door.\u00a0 if the door opens they jump in, start the car and off they go.\u00a0\u00a0 Great.<\/p>\n

So what you can do.\u00a0 For now you can the key fob in your freezer, your freezer is a Faraday cage that will block signals. The longer term solution is to go online and order anti-static bags.\u00a0 They work pretty well. Else just get a box and wrap the outside, or inside with aluminum foil. Remember to test because depending on the thickness of the aluminum foil, you man need to put in two layers.\u00a0 The thickness of the foil has a frequency range that it blocks.<\/p>\n
