Finding the best Faraday and RFID key pouches could prove to be quite important. Inevitably, where there is keyless car tech, there's 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 such as steering wheel locks, a mechanical solution, or make sure you always park in a secure garage.
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. This neatly brings us to the convenience of RFID key pouches.
The best RFID key pouches 2025 at a glance
You can of course, opt for outdoor security cameras to be able to keep an eye on your vehicle. Security comes in layers that generally speaking, are better when there's more of them. Because relay thefts are common, simply blocking it might be one of the most effective ways of protecting your vehicle. 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.

FAQs and things to remember about RFID and Farday key pouches
Do RFID and Faraday pouches degrade overtime?
There have been many cases where this is known to happen. They can wear out overtime due to continuous use. If you get a pouch from a reputable manufacturer that is of good quality, it should last you a lot longer than a basic unit.
You can always check its effectiveness by walking up to your car (with the key in the pouch) to see if it'll unlock. If you suspect it's had its day, it may be time to replace that pouch with a new one. Alternatively, you could opt for a Faraday box if you wish to store your keys and phone inside at the same time at home.
How do Faraday pouches 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.
Which Faraday pouch should I buy?
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.
