In the box: 1 x Car Key Keyless Entry Fob Signal Blocker Faraday Bag - Larger Version
Keyless car fobs are always sending out a weak radio signal. In a relay attack, thieves use one device to pick up that signal from your key inside the house and another to pass it to your car, which then unlocks and starts.
A Faraday pouch is lined with metal fabric that blocks radio signals, so a key inside it can't be picked up. Take the key out when you want to drive.
Test it once: put the key in the pouch, close it fully, stand by the car and try the door. If it stays locked, the pouch is working. It's worth testing again now and then, as the lining can wear over time.
