RFID and Faraday pouches are often overlooked in the world of car security products, but they can be massively effective in keeping your car secure. They don’t offer the same amount of physical security as a steering wheel lock, but they offer some peace of mind by interrupting the signal that your key fobs emit to unlock and start your vehicle.
While car technology advances it does mean that we can become more vulnerable to alternative methods of theft, and not everyone will have the best intentions. Keyless technology is one of those concepts which makes our lives easier by transmitting a Radio Frequency Identification (RFID) signal to lock, unlock, and start our cars. It may be more convenient than traditional keys, but it’s also more convenient for unscrupulous individuals to gain access to your car by cloning the RFID signal.
A notable problem has been found with Land Rover vehicles, which have been increasingly targeted by criminals in recent years. JLR issued an update to its keyless entry system and came up with its own insurance policy to tackle the epidemic. Despite the efforts of car manufacturers, we recommend you take the necessary steps to reduce the risk by investing in a Faraday box, bag, or pouch. In the grand scheme of things, it’s a small price to pay for that extra layer of protection to your cherished vehicle.

What is an RFID or Faraday pouch?
Car security has come a long way since the days of steering wheel locks as keyless tech has moved on. Faraday pouches are a type of bag made with materials that block electromagnetic radiation. The pouch is designed to protect electronic devices such as key fobs, smartphones and credit cards from being hacked, tracked, or compromised by electromagnetic signals.
How do Faraday pouches work?
A Faraday pouch uses mesh that blocks electromagnetic signal. When an electronic device is placed inside, its signal is protected from leaving the pouch. This prevents thieves or hackers from accessing the RFID signals coming from the device. Unfortunately, they’re not 100% effective.
While they can block a significant number of electromagnetic signals, some may still be able to penetrate the pouch. In addition, the effectiveness of the pouch may be reduced over time as the materials degrade or become damaged. The important thing to note is that a Faraday pouch is a proactive measure to prevent your car from being taken in the first place. And if you’re feeling extra conscious, we’ve also made a guide on the best car trackers.

The best RFID Faraday pouch
Straight away, I liked the sturdy construction and premium feel. The materials seem to be of really good quality, so it looks like this is made to last. The design is the ideal size for a single key fob, and the Velcro closure strip provides a firm, secure seal. Getting a good seal is really important with Faraday products because it can affect how well they work.
The real test of any Faraday pouch is its signal-blocking capability, and the Disklabs pouch performs splendidly. In practical testing with a car key fob, the pouch successfully prevented both unlocking and starting the vehicle when the fob was in the bag with the cover closed. This shows effective RF signal blocking, which is exactly what you want for protecting against relay attacks and keyless car theft. Interestingly, even with the flap partially open, there was still some level of protection, though I wouldn't recommend this for day-to-day use. It's not the cheapest pouch on our list, but the Disklabs Faraday Bag successfully combines robust construction with effective signal blocking.
Disklabs also provide larger Faraday Bags.
The Disklabs Key Shield Home (KS3) is suitable for holding multiple key fobs, is great for homes with more than one vehicle, and it's large enough to protect a mobile phone, too.
If you have any concerns about the information security of your laptop while you are travelling, there is a solution.
The Disklabs Tablet Shield measures 30cm x 40cm and is suitable for securing your device from unwanted interference, including remote wiping, remote location tracking and preserving evidence.

Best Faraday pouch for smartphones
The first thing I noticed about this pouch is its size and shape, measuring in at 192mm x 100mm x 9mm - it looks more like a purse than a pouch, but there is a reason for this. The larger size compared to many competitors means it can handle bigger key fobs and even smartphones. The idea is that you can put your smartphone in the pouch as you drive. The RFID protection means it won't receive any signals, so you won't be distracted when you are on the move. It can also be used to protect your mobile from hackers taking advantage of contactless technology.
The pouch is still nearer the budget end of the market, and the feel of the material used kind of reinforces that, but it does have a strong, secure Velcro fastening and keyring hook. The purse-like design gives it a totally different look compared to some of the more techy-looking Faraday pouches.
The inclusion of a keyring hook adds practical value, making it easy to attach to bags or belts. Stoplock also suggests it's "ideal for safely storing your phone while driving, helping you to avoid distractions and stay focused on the road.", though this may be of limited appeal considering many of us use mobile phone apps like Google Maps as we drive.
In my home test, it worked fine. I was unable to unlock or start my car when the fob was in the correctly sealed pouch, although, personally, the size makes it just too cumbersome for my liking. The Stoplock RFID Pouch is a good, budget-friendly option for RFID protection that offers good value and versatility with its larger size.

Best simple Faraday pouch
In our test, it performed exactly as promised. With the fob sealed inside, we couldn’t unlock the car remotely, nor could we start it once inside the cabin. That signal-blocking ability confirms it works effectively in real-world use.
Priced at around £11, it’s both affordable and robust enough for daily use. Some owners have reported reduced performance over time, so it’s worth checking periodically. Still, for those after a practical, budget-friendly deterrent, the Disklok pouch is a solid option.
Review by Alex Boyd
Pros
- Good value for money at around £11 for a small size
- Carabiner clip included, making it easy to hang onto things
- Can be used for cards as well as key fobs
Cons
- Not quite large enough for smartphones
| Dimensions | 14 x 9.5 cm |

Best budget Faraday pouch
Good value comes from the fact that you get two pouches in the pack, making it a sensible buy for households with more than one car. They’re generously sized too, easily accommodating a fob with space to spare, or even a medium-sized smartphone if you need to shield that as well.
Build quality feels solid, with tidy stitching and a secure closure. The only weak point is the small hook on the back, which doesn’t feel robust enough for daily clipping. Still, as an affordable and practical deterrent, the Defender Signal Blocker is an excellent choice.
Review by Alex Boyd
Pros
- Very good value for money at under £10 for the pack
- Comes as a twin pack, meaning you can protect two things at once
- Large enough to fit a smartphone, increasing its versatility
Cons
- Not quite as efficient for pocket carrying use
- May need to be replaced after several months

Best leather pouch
Measuring 14.5cm × 9.3cm, it’s a practical size that comfortably fits a modern key fob, plus extras such as a keyring or even a card. A small carabiner clip on the back adds convenience for clipping onto a belt or bag, but it doesn’t feel particularly rugged, so it’s best treated as a light-use feature.
In testing, the Ironstripe pouch proved reliable. With the fob sealed inside, we couldn’t unlock the car remotely or start the engine once inside. That dependable signal blocking makes it a strong choice for everyday protection.
Review by Alex Boyd
Pros
- Premium carbon-effect leather finish
- Handy carabiner clip for attaching to bags or belts
- Three-year warranty for some extra reassurance
Cons
- Styling may be too bold for minimalist tastes
- Carabiner feels a little lightweight

Best budget Faraday pouch
Adding to the parade of anti-theft devices is the AA1872 AA Anti-Theft RFID Pouch. It's the ideal size for a single key fob and won't be too cumbersome to carry around in a bag or a pocket. Its appearance doesn't look terribly luxurious, but neither does it look cheap and nasty, and when you actually use it, you get the sense that it's a reasonably sturdy pouch. I must admit, the first time I used it, it took a few seconds to work out how to put the key fob in. As you can see in the picture below, the shielding material comes right up almost to the top of the pouch rather than to the opening fold, which might be expected.
As far as performance goes, I didn't encounter any issues at all. I tried to open the car while standing next to it with the fob in the pouch, no luck. Then I tried to start the car while inside; again, the pouch did its job. It's a no-frills solution, but it is good value.
The pouch we tested, the AA1872 RFID Anti-Theft Pouch (pictured above), is no longer widely available, but a newer version is now sold as a double pack. Based on the AA’s reputation and the quality of the original, we would expect the updated version to live up to the same high standards - both in performance and in build quality - and to meet the expectations of the public.
Review by Alex Boyd
Pros
- The AA is a trusted brand here in the UK
- Ideal size for a single key fob. Small enough to fit in a pocket or bag without being intrusive
- Good value. Offers a functional solution to keyless car theft without unnecessary frills
Cons
- Basic Appearance. The design is fairly plain so it may not appeal to those looking for a premium or stylish accessory
Editor's choice

FAQs and what you need to know about RFID and Faraday pouches
-
How can I test my Faraday pouch?
It is actually very simple to test your pouch, and we recommend that you do it often to ensure your pouch is working properly. Simple place your car keys inside the pouch and approach your car. If your car unlocks then it means your pouch is ineffective and needs to be replaced, but if your car doesn’t unlock at the range that it usually would then that means your pouch is offering the protection that you need.
-
Is it worth getting a Faraday pouch?
RFID and Faraday pouches are a key layer of protection if you don’t fancy physical deterrents such as wheel clamps. If you are concerned about your keyless vehicle’s security, a Faraday pouch can be a good investment. As well as your key fob, a Faraday pouch can protect your credit cards and phone as well. For a relatively small investment, it can give you some peace of mind.
-
Do Faraday pouches wear out?
Yes, Faraday pouches can wear out over time, especially with extensive use. If your pouch develops holes, or the material starts to wear down, then the signal can find its way through rendering the pouch ineffective. It is important to find a good quality pouch that will last a long time, otherwise you may find yourself having to buy another pouch very soon. You should also make sure that you’re closing your Faraday pouch properly otherwise it won’t do its job of protecting your keys signal.
