Questions and Answers
How do Faraday Pouches Work?
A Faraday bag works because radio waves move through electric fields which interact with the charges that are naturally present in metal electric fields pushing positive charges away from them. This means that when they hit a faraday bag or pouch the negative charges collect on the side of the bag nearest the signal source whilst the positive electrons accumulate on the other side becoming the incoming field. The positive to negative direction now since the charges in the metal have become orientated themselves in the opposite direction they produce their own electric field going the other way, meaning that they cancel each other out inside the pouch and the radio waves can’t pass through, therefore protecting your keys.
Police have advised people in the UK with wireless ignition systems to keep their keys in a Faraday bag or tin to prevent relay car theft where thieves read the signal off of your key fob from outside the house start your car and then drive away.

The simple answer is no you need a Faraday box or pouch to protect your key from transmitting a signal. Moving your key away from the door should help prevent your car key from transmitting but with the thief’s increasing signal range technology the best option is to buy a box or pouch.
