Quick hack if you need to act now.

Wrap your 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 (worth a try if you are in a pinch).

Experts recommend the FANACAN Signal Blocking Bag for total security. However there are some draw backs with this design. It only fits one key, but would stop your vehicle from being cloned when out and about and in the house. They are great for every day carry as may people will have their key cloned when out and about.

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.

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

Will Wrap Car Keys In Foil To Prevent relay theft.

Thieves use relay boxes to capture the signal from a target vehicle and then use it to wirelessly unlock the vehicle. In order to thwart this type of theft, some car owners have been wrapping their car keys in foil. This simple technique can effectively block a signal from being captured by a relay box, preventing your keys from being used to steal your car. But it may not work all the time you will have to test this with your make and model of key.
