About this deal

A poor-quality Faraday bag may stop working because it has failed and can no longer prevent the signal from escaping. Whenever you think your car key might be vulnerable to having its signal grabbed. Ironically, the easiest cars to steal using relay theft are those parked on people’s drives. The thief knows exactly where the keys for that car are: somewhere behind the front door.

Just as they don’t allow the signal to escape, neither do these bags allow any signal to enter. So once in a Faraday bag, your car key will neither transmit nor receive. Do Faraday bags work for car keys? In some cases, biscuit tins will work as a Faraday bag; in other cases not. Put your keys in a biscuit tin and if it has a tight-fitting lid, it should prevent signal getting through. If the signals are very strong, it might not. Obviously it has to fulfil its primary purpose of isolating the signal from the key. Good ones are made from several layers of copper and plastic. But if you want to make your own, you could use aluminium kitchen foil and paper.This Disklabs bag is as well constructed as the larger phone version (left) and has Secured by Design accreditation, too. It also has a handy lip on the flap, so it is easier to pull open. Relay theft has been around for a couple of years now and car makers have got wise to crooks. Some car companies now make keys that don’t emit a signal unless they’re moving, or after they’ve been stationary for a short period of time. Other’s make keys that can be turned off if they’re not needed.

Make sure you can still access the sandwich bag’s opening (the fourth edge that you don’t seal). To see how good the item really is, put your mobile phone in it (assuming it fits). Then ring your phone. A fully functioning Faraday bag should prevent the signal getting through to your phone. What makes a good Faraday pouch?The bag must be fit for purpose too. Some people might want a Faraday bag that’s portable; some might want one that they can just leave in their house for when they’re at home. The latter might be able to get away with a less robust article.
