Introduction
Keyless entry to your automobile is very convenient. – Car thieves are catching on to this high-tech invention. Relay attack devices use criminals to read the signal from the key somewhere outside of your house. It’s as simple as that: after they’ve duplicated the code, they can get into your car and drive away.
Put your key in a Faraday bag as a safety precaution. These bags are covered with sheets of metallic material that obstruct the signal from the key. Making it impossible for criminals to get access. Once you’ve locked your car, you’ll need to put the key right into the bag. You can even store your smartphone and debit cards inside if you get a large bag, which is a proven way to avoid hacking or fraud.
If you’re going to buy a Faraday key fob protector, you’ll want to make sure you get one that works well. Fortunately, we were able to put eight of them to the test.
Inspection
We began by placing the key in the bag and holding it against the automobile door handle. Then we tried to unlock the automobile by using the signal from the key and using the key’s controls to free the lock. We attempted to start the car by hitting the starter button once there.
We also used an app to check for transmission on the phone, Wi-Fi, and Bluetooth. We also gave each product a score based on its construction quality, size, and convenience of use. All of this was weighed against the cost per kilogram. Many businesses have begun to release different faraday bags key signal blockers in recent years.
However to assist you in selecting the best. We conducted extensive testing and research taking into account a variety of criteria. The size, convenience of putting your key inside the bag or box. Design, warranty, and value for money were all criteria we examined.
Although Faraday bags are supposed to be larger than the key, there are options in the shape of a box that can hold numerous keys. For automobile keys, there’s a faraday bag. In terms of our testing, we explored a variety of alternatives from top-rated UK manufacturers, as well as a variety of keys.
Some products
Defender Signal Blocker
The Defender is remarkable because of its size and weight: at 42g. It’s the second heaviest bag on the list, but it’s also the second biggest and inexpensive by a long shot. Cell, Wi-Fi, and Wireless signals were all completely blocked. Once the phone was placed within the bag, according to our tests.
The Defender also has enough room for one of the new generation of big-battery phones (155 x 75). As well as a flat Renault key – albeit a BMW counterpart was a tight fit. It’s a little thick if you’re simply using it as a key. It still values it for the great build quality, smartphone option, and amazingly price tag.
Disklabs Key Shield Faraday Bag KS1
Only the Disklabs Key Shield has a ‘Secured by Design’ police certification. It is a stamp of approval that will give you a lot of peace of mind. We appreciated its craftsmanship, which included exceptionally strong stitching over the thick cloth. We’re convinced that this wallet will last for many years. With a surface area of 120 square centimetres, it will easily accommodate keys of all sizes.
Even while the flap was open, it operated admirably. Although it is the most expensive of the goods we reviewed, it is a wise investment given the quality and performance it provides.
Ecence RFID Radiation Protection Bag
Ecence’s Faraday bag looks very similar to those from Halfords and B-G, which are farther down the list. Its substance is thick and comparable to that of the Disklabs wallet. It appeared to be prone to splitting after prolonged use. We weren’t happy with the connection at the lower edge. The device appears to have been created specifically for key storage and to be fair, our test keys were a tight fit. It did an excellent job of blocking the key’s signal. Its low price made it a better product than the two we described earlier.
B-G RFID Faraday Bag MIS1003
B-G offers two Faraday bags, the second of which is super-sized and, like the Defender, appropriate for mobile phones. This mini version ranked to the Halfords and Ecence wallets, with the same advantages and disadvantages. There’s a simple chrome ring on the back that you can hang wherever you want, and a regular keyring on the top. If you do clip your car key to the wallet, however, getting inside is quite difficult. And, obviously, you’ll have all of your additional keys on the same ring, making the whole process a tad complicated.
Halfords Anti RFID Theft Wallet
The Halfords bag scored poorly on price. It outperformed the B-G and Ecence bags on every other parameter. We liked the wallet’s appearance. It appeared to be durable enough to survive frequent use. Although the ugly join was a shame. Its two-ply copper layer effectively stopped any signal leakage. The internal compartment may be used to hold money and receipts. And, unlike the other two, it appears to be designed for collaborative credit card use. It contains space for several cards beside a key.
TVL Anti Scan Wallet
This TVL Faraday bag is like the TrackingUK one at the end of the list. It did a fantastic job of filtering phone signals when the flap was closed. Another vinyl wallet, this one appeared to be well-made. It is able to withstand repeated opening and closing. We weren’t sure how well it would hold up in a handbag or pocket. It weighed more than half as much as the Tracking UK bag, at 26g. It was the second-most important purchase on the test, yet it blocked all essential signals.
Disklabs Phone Shield Faraday Bag PS1
The Disklabs super-sized wallet, designed for phones, was just as good as its smaller cousin in terms of quality and appearance. It also had the same police certification. We observed it was slightly larger than the Protector and could easily fit and block our phones. It also actually prevented all signals from both the keys and the phone. Placing the latter alongside the bigger VW and BMW keys proved difficult. It appeared to be costly at first glance, but a quick calculation revealed that the price per gramme was lower than typical. It couldn’t quite match the gold-medal Protector in the end.
TrackingUK Faraday Key Signal Blocking Wallet
This bag is the smallest on the list, weighing only 16g. When not in use, we found it to be inconspicuous and convenient to tuck into a pocket. Although the vinyl material and stitching did not completely impress us, it performed admirably. It also worked flawlessly on an iPhone. However only while the flap was closed, which isn’t very useful the time. It was large enough to manage two people individually, but the price was prohibitive.
Conclusion
Car theft, particularly relay crime, isn’t going anywhere any time soon. As a result, purchasing a car key signal jammer for all of your key fobs is strongly advised. For added security, you might purchase an ancient steering lock.
All of our suggestions are suitable for a variety of budgets. It includes all of the many types of signal blockers available. It’s always better to be safe than sorry, regardless of whatever automobile key signal blocker you buy.
