Why is looking for the best Faraday and RFID key pouches important? Well, with keyless car tech, there inevitably come keyless car thefts. An increasingly common form of car theft involves criminals using relay signals that mimic those that come from key fobs to unlock and start cars.
You can opt for existing security measures exist such as car wheel clamps which can physically keep your car nailed to the ground. However, there have been scary cases where premium cars such as Range Rovers and Mercs have been swiped in under a minute. The no.1 method for criminals is relay signals, so being able to block that can prevent a nightmarish situation. Which neatly brings us onto the convenience of RFID key pouches.
The brilliant thing is that they don't incorporate the bulky hassle of a steering wheel lock. The solution simply involves keeping your key fob in a protective Radio Frequency Identification (RFID), signal-blocking pouch or box. These effectively act as a Faraday cage. No signal, no keyless car theft.

How does RFID tech work?
RFID pouches and Faraday bags work by incorporating certain materials such as copper or aluminium foil into the bag or pouch. A layer of aluminium foil, for example, blocks all signals to wireless devices being kept inside them. These include phone networks such as 5G, Wi-Fi, GPS, and Bluetooth. They are as subtle as a well-hidden magnetic tracker in your vehicle.
Consequently, key fobs and other devices are kept safe inside and no relay signal can be produced. It sounds a bit Prepper-ish and conjures images of idiots wrapped in tin foil, building home bunkers beneath their geraniums. Nevertheless, the foil trick works for signal blocking. And thankfully, you can buy some quality products that tactfully hide the survivalist foil beneath a neat layer of fabric.
Our top tip in recommending the best RFID and Faraday product is not to be sucked into the ‘I’m not paying an extra £5 for one that looks the same as the cheap ones’ trick. We’ve found the super-budget ones aren’t always consistent in blocking signals, unlike those that come from established, recognized brands. If it keeps your £40,000 Lexus safe, only a fool would complain about an extra few pounds. For an extra layer of protection - and to potentially lower your insurance premium - you can also consider installing your car with a tracker.
