Take a look at how quickly thief’s can steel your car.

How do Faraday bags/cages 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 charge’s collect on the side of the bag nearest the signal source whilst the positive electrons accumulates on the other side becoming the incoming field. The positive to negative direction now since the charges in the metal have became 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.

Will putting my keys in a biscuit tin prevent my car from being?

 

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 thief’s increasing signal range technology the best option is to buy a box or pouch.

Quick hack if you need to act now.

Wrap you key in tin foil for a temporary measure.  With technology moving so fast thief’s can now pick up key signals from almost anywhere within your home.
