The best Faraday pouches, compared.
Top pick: Samfolk Faraday box and pouch – Highest score: a hallway box with two pouches at about £18.99, stated at 16 × 12 × 10 cm, with 4.6 from 13,508 reviews. Best value: caslord 2 pack Faraday pouch – Best value as the lowest shelf price on the top value band, about £3.59, if you measure the fob and test the car. Updated October 2026.
A Faraday pouch is a soft enclosure with a conductive lining that weakens radio signals from a key fob sealed inside it. If your car uses passive keyless entry, a fob near the front door can answer a relay: one person at the car, one by the house. Police and tell you to test the pouch on your car, cover the spare, and retest every few months. A worn lining looks the same as a working one. A pouch is not a lock, a tracker, or a guarantee the car cannot be stolen another way. Size, closure and the car test are in the [Faraday pouch buying guide](/hub/safes-and-secure-storage/faraday-pouch/sub/faraday-pouch-buying-guide). In the UK the usual buyer is a driver with passive keyless entry who wants to stop a relay attack on the fob, including the spare. Quality is not the logo or a military-grade line. It is whether the pouch still stops your own car from unlocking or starting when the fob is fully inside, and whether it still does that after months of folding.

Question 1 of 2
What are you putting inside?
The Samfolk set is a hallway box sold with two pouches at £18.99, and the listing states the box at 16 × 12 × 10 cm. On amazon.co.uk the line is 4.6 from 13,508 reviews. UK comments often say a sealed fob keeps the car from responding, and they also say the blocking faded after weeks or months and that the box was smaller than they expected. A bullet talks about holding several household keys, which only helps if the lid is shut. On these scores it is the top pick when you want a fixed place by the door plus two pouches for keys that leave the house. It is still a lined box, not a lock, and none of these listings shows a British Standard for shielding. Test it on your own car the day it arrives.
Pros
Cons
Best for: You want one drop by the door for keys that stay in, plus two pouches for keys that go out, and you will test the closed box on the car.
Less suitable: You only need a pocket pouch under £10, or you will leave the lid open beside the front door.
Specifications
Common questions
How many pouches come with the Samfolk box?
The title is a box and pouch two-pack, and the listing describes two pouches with the box. The pack-count field in the comparison table was empty. Check the live amazon.co.uk page before you buy.
Should you test the Samfolk box on your car?
Yes. Seal the fob inside, shut the lid, stand by the car, and check that it does not unlock or start. UK police and Thatcham advise the same check again every few months, because a worn lining looks unchanged.
Is the Samfolk set only for keyless car keys?
The listing also talks about household keys in the box. For overnight key storage, still run the car-key test rather than a phone signal check alone. An open lid does not shield anything.
The yaokvide five-pack is a set of large fabric bags at £29.99, with the size field reading 38.1 × 1.3 × 42.9 cm, which is laptop territory rather than a pocket pouch. amazon.co.uk shows 4.6 from 1,378 reviews, yet only one UK review block is available to read, so the star line is not a stack of UK car-key tests. That thin UK sample still mentions a sealed fob staying quiet, blocking that later faded, and an awkward closure. The bullets describe a double roll and Velcro. The title says the bags are fireproof and waterproof, and these fields do not include a BS or EN number. At nearly £30 you are buying five large bags, which is a poor match if you only needed two key pouches under £10.
Pros
Cons
Best for: You want several large bags for laptops, tablets, or phones and you will still run a car-key test if a fob goes inside.
Less suitable: You only need overnight storage for one or two car keys and a stated pocket size.
Specifications
Common questions
How many bags are in the yaokvide five-pack?
The listing states a pack of five, sized at 38.1 × 1.3 × 42.9 cm. That is a laptop-sized bag, not a pocket pouch for a single fob. About £29.99 is the price for the five.
Does the five-pack prove fire resistance?
The title says the bags are fireproof and waterproof. No BS or EN number appears in these listing fields. Treat that line as listing copy, not as a rating for a document safe.
How much UK review text is there for the five-pack?
amazon.co.uk shows 4.6 from 1,378 reviews, and only one UK review block is available to read. That block mentions a sealed fob staying quiet, later fading, and an awkward closure. It is not a large UK car-test sample.
The lanpard small pair is listed at £6.99, and the bullets state 11 × 7.5 cm. Those same bullets tell you to choose medium or large for Tesla and other larger keys so the flap can close. amazon.co.uk shows 4.5 from 50,638 reviews, the same star line as the medium lanpard listing, so you should not add the two counts or treat them as separate tests. UK comments praise blocking when the pouch is sealed, light carry, and the two-pack for a spare. They also mention fading after weeks or months, a tight size, and a closure that is awkward to seal. The title says two pack, while the pack-count field was empty. It is the compact lanpard option when your fob fits inside 11 × 7.5 cm with the flap fully shut.
Pros
Cons
Best for: Your fob is small enough to seal inside 11 × 7.5 cm, and you want a second pouch for the spare.
Less suitable: You have a Tesla or another large fob the listing tells you to size up for, or you need a hallway box.
Specifications
Common questions
How big is the small lanpard pouch?
The bullets state 11 × 7.5 cm and tell you to move up a size for Tesla and other larger keys so the flap can close. A pouch that will not shut over the fob is not shielding it.
Are the 50,638 reviews only for this size?
No. The medium lanpard listing shows the same 4.5 from 50,638. Treat that figure as one shared line, not as two tests you can add together.
Does the small lanpard listing claim to be waterproof?
Waterproof is named in the bullets. No British Standard number for water or shielding is in these listing fields. Test the closed pouch on your own car.
The lanpard medium pair is listed at £3.99, with a bullet size of 9 × 14 cm and a double set for a spare fob. The amazon.co.uk line is 4.5 from 50,638 reviews, identical to the smaller lanpard ASIN, so that figure is one shared line rather than proof unique to this size. UK comments praise a sealed fob, the two-pack, and light carry. They also mention blocking that faded after weeks or months, a pouch smaller than expected, and a closure that is awkward to seal. The title says two pack, but the pack-count field here was empty. It is a low-price key pouch with a centimetre size you can compare with your fob. On value it ties the cheaper caslord pair, and the higher shelf price is why it does not take the best-value place.
Pros
Cons
Best for: You want a stated 9 × 14 cm pair near £4 and you will test both pouches on the car.
Less suitable: You are choosing only on the 50,638 figure, or you need the lowest price in the set.
Specifications
Common questions
What size does the medium lanpard pouch state?
The bullets state 9 × 14 cm. UK reviews include a pouch smaller than expected, so compare that rectangle with your fob and any cover before you buy the pair for the spare.
Why is this not the best value at about £3.99?
It ties caslord on the top value band. caslord is about £3.59, and the tie goes to the lower shelf price. The medium lanpard pair does print a centimetre size, which caslord does not.
Is the 50,638 count unique to the medium pouch?
No. The small lanpard listing shows the same 4.5 from 50,638. Do not add the two counts. UK comments on this size also mention fading and an awkward closure.
The WHonor pair is a hook-and-loop key pouch listed at 14 × 9 cm and 55 g, sold as two pouches for £7.99. On amazon.co.uk the line is 4.5 from 9,772 reviews, and UK texts often say a sealed fob stops the car responding. The bullets claim the lining blocks RFID, NFC and keyless signals completely, which this comparison does not measure. Reviewers also say the pouch feels bulky for everyday carry, and several say the blocking faded after weeks or months. Closure comments describe the hook-and-loop as awkward when the fob is thick. You do get a spare pouch in the same order. It is still fabric that needs a car test on the day it arrives and again every few months.
Pros
Cons
Best for: You want a named two-pack around 14 × 9 cm and you will test both fobs on the car rather than trust a total-block line.
Less suitable: You need a hallway box for several keys, or you want a listing that does not claim a total block.
Specifications
Common questions
What size and weight does WHonor state?
The listing states 14 × 9 cm and 55 g, sold as two pouches, with a hook-and-loop closure. UK reviews call it bulky for everyday carry and awkward when the fob is thick.
Does the WHonor listing prove a total signal block?
The bullets claim a complete block of RFID, NFC and keyless signals. That claim is not a measurement in this comparison. UK texts also say the blocking faded after weeks or months. Test the sealed fob on your car.
How many WHonor pouches are in the pack?
The listing states a pack of two at about £7.99. That second pouch is the one for the spare fob. An unprotected spare by the front door defeats the pouch you carry.
The caslord pair is the lowest shelf price in this set at £3.59, with 4.5 from 4,635 amazon.co.uk reviews and a title that says two pouches. The bullets name Velcro and four key rings, while the comparison row also records a roll-top, so the closure is not a single agreed line. No centimetre size is printed. UK reviews praise a sealed fob and the spare pouch, and they also mention bulk, fading after weeks or months, and an awkward closure. On these scores it is the best value when you want the cheapest two-pack and you will check that your fob actually fits before you rely on it. A low price does not show that the lining will still work after months of folding.
Pros
Cons
Best for: You want the cheapest two-pack in this comparison and you will measure the fob and test the car yourself.
Less suitable: You need a printed size, a hallway box, or a closure described the same way in every field.
Specifications
Common questions
Does caslord state a pouch size?
No centimetre size is printed. The title says a two-pack, and the bullets name Velcro and four key rings. Measure your fob, including any case, before you rely on the flap closing.
Why is caslord the best value if lanpard is also under £4?
Both sit on the top value band. The lanpard medium pair is about £3.99 and the caslord pair is about £3.59. The tie goes to the lower shelf price. caslord has no printed size, so the saving only holds if the fob fits.
Should you test the caslord pouch on the car?
Yes. Seal the fob, stand by the car, and check that it does not unlock or start. UK reviews mention blocking that faded after weeks or months, so repeat the check rather than treating the first night as permanent.
The Teskyer listing is a two-pack of key pouches at £9.99, stated at 13 × 9 cm, with a hook and an inner key ring. amazon.co.uk shows 4.4 from 2,921 reviews. UK texts praise a sealed fob that stops the car responding, and they also call the pouch bulky, say the blocking faded after weeks or months, and describe the closure as awkward. The bullets name PU and a thickened lining, and they do not state a water or fire standard. You pay more than the caslord or lanpard medium pairs for a similar fabric pouch with a printed size. The title says two pack, while the pack-count field was empty. It suits a buyer who wants pouches around 13 × 9 cm and will retest them.
Pros
Cons
Best for: You want a 13 × 9 cm pair with a hook and you accept retesting rather than the lowest price.
Less suitable: You are shopping only for the cheapest two-pack, or you need a box that holds several keys at once.
Specifications
Common questions
What does Teskyer state for size?
The listing states 13 × 9 cm, with a hook and an inner key ring, in a two-pack title at about £9.99. The bullets name PU and a thickened lining. They do not state a water or fire standard.
How does Teskyer compare on price with the cheaper pairs?
At about £9.99 it costs more than caslord at about £3.59, lanpard medium at about £3.99, lanpard small at about £6.99, and WHonor at about £7.99. You are paying for a printed size and a larger review count than the cheapest pair, not for a laboratory test.
What do UK reviews say about the Teskyer closure?
UK texts praise a sealed fob that stops the car responding. They also call the pouch bulky, say the blocking faded after weeks or months, and describe the closure as awkward. Retest every few months.
The Hodufy pouch at £12.98 is titled as 9.8 × 11 inches for keys, tablets and phones. amazon.co.uk shows 4.4 from 218 reviews. A bullet claims the fabric stands up to 1,832°F (1,000°C) and is highly water resistant, with no BS or EN number beside the claim. UK reviews praise blocking when the bag is sealed, and they also call it bulky and say the effect faded. At least one UK test says a phone or other signal still got through, and the closure is described as awkward to seal. You are buying a phone-sized fabric bag rather than a 9 × 14 cm key pouch. Treat the fire line as listing copy, not a rating for a document safe.
Pros
Cons
Best for: You want a mid-size phone bag and you will reject it if your own car still unlocks.
Less suitable: You want a small key pair, or you would treat a phone test and a fire bullet as proof.
Specifications
Common questions
What size is the Hodufy 9.8 × 11 inch pouch?
The title states 9.8 × 11 inches, for keys, tablets and phones, at about £12.98. A pack count is not stated. It is a phone-sized bag, not a 9 × 14 cm key pair.
Did a UK review find a signal getting through?
Yes. At least one UK test says a phone or other signal still got through. Other UK reviews praise blocking when the bag is sealed, and also mention bulk, fading, and an awkward flap. Test it on your car and reject it if the car still responds.
Is 1,832°F a British Standard on this pouch?
No. A bullet claims 1,832°F, which is 1,000°C, and high water resistance. No BS or EN number is in these listing fields. The fire line is not a document-safe rating.
The yaokvide phone bag is a roll-top, Velcro fabric pouch at £12.99 and about 100 g, aimed at phones as well as keys. amazon.co.uk shows 4.4 from 174 reviews, but there is no UK review text to read, so you cannot see whether buyers passed a car test. Pack fields disagree: one line says 1, another says a 2-pack, and another says 5. The bullets claim the bag is fireproof and waterproof with no British Standard or EN number. Dimensions in centimetres are not printed. It is a phone-sized bag in the middle of the price band. It is a weak choice if your only job is overnight key storage with a known size.
Pros
Cons
Best for: You want a foldable phone bag and you will confirm the pack count on the live amazon.co.uk page.
Less suitable: You only need a key-fob pair with a stated size and UK comments about a car test.
Specifications
Common questions
How many yaokvide phone bags are in the pack?
The fields disagree: one line says 1, another says a 2-pack, and another says 5. Confirm the live amazon.co.uk page before you buy.
Is there UK review text for this phone bag?
There is no UK review text to read, although amazon.co.uk shows 4.4 from 174 reviews. You cannot read a car-key test from this comparison. Run that test yourself if a fob goes inside.
Does the phone bag state a size or a fire standard?
No centimetre size is printed. The bullets claim the bag is fireproof and waterproof, and no BS or EN number is in these fields. Weight is about 100 g. The closure is named as roll-top and Velcro.
The YourSecure case, sold by eStocker Trading Ltd, is a rigid anodised aluminium shell at £39.99, the highest price in this set. The bullets limit it to one fob up to 80 × 40 × 20 mm and name brands such as Audi, Mercedes, Ford, Toyota and Volkswagen as examples, not as a measured fit list. amazon.co.uk shows 4.4 from only four reviews. Those UK texts mention blocking when the case is shut, fading, and an awkward closure, which is a thin sample. Waterproofing is claimed in the bullets without a standard number. It is one rigid case, not a hallway box and not a two-pack. It covers a spare key only if you buy a second case or keep that spare somewhere else that you have also tested.
Pros
Cons
Best for: You carry one fob that is within 80 × 40 × 20 mm and you prefer a rigid case to fabric.
Less suitable: You need two keys covered for the price of a fabric pair, or you want a sample larger than four reviews.
Specifications
Common questions
Is the YourSecure case a hallway box?
No. It is one rigid anodised aluminium shell for a single fob up to 80 × 40 × 20 mm, sold by eStocker Trading Ltd at about £39.99. Brand names in the bullets are examples, not a measured fit list.
How many reviews does the aluminium case have?
amazon.co.uk shows 4.4 from four reviews. Those UK texts mention blocking when the case is shut, fading, and an awkward closure. Four reviews are a thin sample beside the fabric pairs.
Does one YourSecure case cover the spare fob?
No. It holds one fob. The spare stays exposed unless you buy a second case or store that spare in something else you have tested on the car.
The Hodufy laptop pouch is listed at £18.89 with a folded size of 16.9 × 15 inches in the title. amazon.co.uk shows 4.3 from 757 reviews, and 18 UK review blocks discuss it. Those texts praise a sealed item staying quiet, and they also mention blocking that faded and a closure that is awkward to seal. A bullet claims the fabric stands up to 2,000°F, with no British Standard or EN number beside it. Water resistance is claimed in the same style. This is a large sleeve for a laptop or several devices, so using it only for one key fob means folding a lot of fabric shut every night. It can hold a fob, but the car test still has to be done on your own car.
Pros
Cons
Best for: You want a laptop-sized bag that can also take a fob, and you will retest because reviews mention fade.
Less suitable: You only need a key pouch near £4 to £8, or you wanted a certified fire safe.
Specifications
Common questions
What size is the Hodufy laptop pouch?
The title states a folded size of 16.9 × 15 inches. The listing price is about £18.89. A pack count is not stated. It is a laptop sleeve, so it is larger than a key-fob pair.
Is the 2,000°F line a British Standard?
No. A bullet claims the fabric stands up to 2,000°F, and no BS or EN number sits beside that claim. Do not treat the pouch as a document safe.
What do the UK reviews of the laptop pouch say?
Eighteen UK review blocks praise a sealed item staying quiet. They also mention blocking that faded and a closure that is awkward to seal. The amazon.co.uk line is 4.3 from 757 reviews. Retest on your own car.
The Hodufy handle bag is listed at £15.89 with 4.2 from 18 reviews, the lowest star line in this set. The title calls it a signal jammer, which is the wrong word for a passive shield, even though the product is still a bag rather than a transmitter. The title says 13 × 10 inches, the size field prints 13.97 × 1.27 × 30.48 cm at 150 g, and another size line says 5 pack against a pack count of 1. Five UK texts include at least one report that a signal still got through, plus size complaints and an awkward roll-and-Velcro closure. A bullet claims 2,000°F with no British Standard number. It is a large carry bag with a handle, and the conflicting size lines make it a poor default for overnight keys.
Pros
Cons
Best for: You want a handled laptop bag and you will ignore the jammer wording and test the seal on your car.
Less suitable: You want a clear key-pouch size, a two-pack, or a listing whose pack count stays on one number.
Specifications
Common questions
Why does the Hodufy handle bag say jammer?
The title uses the word jammer. A lined bag is passive shielding, not a transmitter. Ofcom does not license jammers, and using apparatus to cause interference is illegal under section 68 of the Wireless Telegraphy Act 2006 unless authorised. Do not buy this bag in order to transmit interference.
Which size line should you trust?
They disagree. The title says 13 × 10 inches, a size field prints 13.97 × 1.27 × 30.48 cm at 150 g, and another size line says 5 pack against a pack count of 1. The table leaves stated size blank for that reason. Check the live page.
Did UK reviews find a leak on the handle bag?
Five UK texts include at least one report that a signal still got through, plus size complaints and an awkward roll-and-Velcro closure. The amazon.co.uk line is 4.2 from 18 reviews. A 2,000°F bullet has no BS number.
Twelve amazon.co.uk listings were scored on a 0–100 scale from the star line, the review count, whether the product fits a keyless fob, themes in the UK review text, and the GBP shelf price saved on 19 October 2026. A star rating is not a measurement of shielding. None of these listings shows a British Standard, a UKCA shielding test, or a Secured by Design mark. The two lanpard listings share one review count, so that figure is not treated as two separate tests. The top pick is the highest score. Best value is the strongest price score, and a tie on that score goes to the lower shelf price. Weights sum to 100. In sentences this page says top pick and best value.
Amazon evidence
30%30 points. Stars and the review count both count, with a cap so a huge shared count cannot carry the whole score. The two lanpard listings show the same 50,638 reviews, and that shared line is reduced rather than counted twice.
Listing fit for a keyless fob
40%40 points. A key-fob pouch or a hallway box with pouches fits the usual overnight job better than a phone bag, a laptop sleeve, or a rigid case for one fob. A named closure, a stated size, cover for a spare, and a car-side check in the bullets add weight. A pack-count clash, the word jammer in the title, or a fire temperature with no BS or EN number takes weight off.
Review outcome
15%15 points. UK review text that describes a sealed fob staying quiet scores higher when the sample is large. Fading after weeks or months, an awkward closure, a thin UK sample, or a signal that still got through all reduce it. No UK review text scores low.
Value
15%15 points. A two-pack at or under £4 scores highest, then pairs under £8 and under £12, then a hallway box under £20. A single bag or a rigid case at £39.99 scores less. A signal that still gets through, a pack-count clash, or a fire claim with no BS or EN number is a deduction. The best-value tie goes to the lower shelf price.
Choose the job before the star count. A key-fob pair, a hallway box, a phone bag, a laptop sleeve and a rigid case for one fob answer different jobs, and the amazon.co.uk prices in this set run from about £3.59 to about £39.99. A 4.6 from 13,508 reviews is a different record from 4.4 from four reviews, and a star line shared by two lanpard sizes is one line, not two. The pouch only counts if it closes over your fob and your own car stays quiet.
A Faraday pouch is a soft enclosure with a conductive lining that attenuates radio signals from whatever you seal inside it. In the UK the usual buyer is a driver with passive keyless entry who wants to stop a relay attack on the fob, including the spare. Quality is not the logo or a military-grade line. It is whether the pouch still stops your own car from unlocking or starting when the fob is fully inside, and whether it still does that after months of folding.
Several bullets say the lining blocks every RFID, NFC or keyless signal, or call the fabric military-grade. None of these 12 listings shows a British Standard, a UKCA shielding test, or a Secured by Design mark. UK reviews still describe fading and, on some bags, a signal that got through. The car test is the check that line cannot replace.
A pouch on the key you carry does nothing for a second fob in a bowl by the front door. Thatcham and the police advice both say the spare has to be covered too. A two-pack only helps if the second pouch is used. A single aluminium case at about £39.99 covers one fob.
Hodufy bullets claim 1,832°F or 2,000°F, and some yaokvide titles say fireproof, with no BS or EN number in the listing fields. That is not a document-safe rating. A phone that loses signal is also not proof the car will stay locked. Use the car, and retest after a few months.
Start with the job. A key-fob pair is for the fob and the spare. A hallway box is for several keys that stay by the door, and it only works if the lid shuts. A phone bag or a laptop sleeve is a different object, and a car-key test alone is the wrong way to judge it. The YourSecure case is one rigid shell up to 80 × 40 × 20 mm, not the Samfolk box. Then match the opening to the fob. Hook-and-loop, a roll-top, a zip and a rigid lid all fail if a thick fob or a second key stops them closing.
Metropolitan Police, British Transport Police and Tracker describe the same check: fob fully inside, closure shut, stand by the car, and see if it unlocks or starts. Do it the day the pouch arrives. A phone test is not that check. Ofcom says no pouch is perfect. A button-press fob is not the relay Thatcham describes, where one person at the car and one by the house stretch a challenge of about two metres. Retest every few months.
Three typical situations, each with a recommendation from this comparison.
You want one shut place for keys that stay in, plus pouches for keys that leave the house. The Samfolk set at about £18.99 is a hallway box stated at 16 × 12 × 10 cm, sold with two pouches, at 4.6 from 13,508 reviews. UK comments also mention fading and a box smaller than expected.
You want the cheapest two-pack in this set and you will measure the fob yourself. The caslord pair is about £3.59, with 4.5 from 4,635 reviews. No centimetre size is printed, and the closure is described as both Velcro and a roll-top.
You want a large fabric bag, and a car-key test is only part of the job. The Hodufy laptop pouch at about £18.89 is titled 16.9 × 15 inches, with 4.3 from 757 reviews. A bullet claims 2,000°F with no British Standard number. It is oversized if the only job is one key.
The top pick is the Samfolk Faraday box and pouch at about £18.99. It is a hallway box stated at 16 × 12 × 10 cm, sold with two pouches, and the amazon.co.uk line is 4.6 from 13,508 reviews. UK comments praise a sealed fob and also mention fading and a smaller-than-expected box. The best value is the caslord two-pack at about £3.59, the lowest shelf price on the top value band, with 4.5 from 4,635 reviews and no centimetre size. The lanpard medium pair ties that value band at about £3.99 and loses the tie on price. A shared star line, a fire temperature with no BS or EN number, and the word jammer in a title are not test results. None of these scores is a laboratory measurement, or a claim that the car cannot be stolen another way.
