Police approval, or “Secured By Design”, is the official accreditation which you should be looking for in business and home security. It is just about the most important stamp of approval a product can receive, and means that the design specifications are of the highest level. Buying an “SBD” faraday pouch is the best guarantee you can get that the signal blocking key pouch you have is going to do a good job at preventing you from becoming a victim of relay theft.

What Makes A Faraday Pouch “Police Approved”?

Police approval is a difficult to define precisely, but looking for a “secured by design”, or SBD rating is the best way to find a faraday pouch or box which is approved by the police. Secured By Design is an initiative by the police, which recognises good products by rating them as having “police preferred specification”. SBD covers all sorts of different product specifications and even covers the design of buildings, but we are going to be looking at the police approved products under the “RFID Security” category.

Products which are rated as “Secured By Design” can be found in the SBD database. To become accredited under this scheme is a very challenging process and only the best of the best manage to get the award.

Which Companies Sell Police Approved Signal Blockers?

The only companies listed in the SBD database for being recognised as selling police approved signal blocking products are the following:

  • Disklabs Ltd
  • Disklok Ltd
  • JNE Security Ltd
  • Solon Security Ltd

Police Approved Signal Blocking Key Pouches

Here is a list of official police approved signal blocking pouches for car keys listed on the database.

  • KEY SHIELD HOME KSH
  • KEY SHIELD KS1 
  • DISKLOK RFID FARADAY SIGNAL BLOCKING WALLET
  • RFID SIGNAL BLOCKING DRINKS SAFE CAN
  • MINDER SIGNAL BLOCKER AND MINDER MINI SIGNAL BLOCKER
  • DEFENDER SIGNAL BLOCKER
  • DEFENDER SIGNAL BLOCKER MINI

These 7 signal blockers from the four companies listed above have all been tested and approved by the police. This level of protection ensures you’re getting the best protection that money can buy.

There may be more products added to the database over time, but that’s every single faraday pouch specifically for car keys I could find in the database.

These faraday pouches aren’t unaffordable either. The Defender Signal Blocker is well under £10, and even the larger, more expensive options don’t cost an arm and a leg. Let’s take a look at the best options out of the seven and their advantages and disadvantages.

Defender Signal Blocker – Best Cheap Faraday Pouch

This signal blocker is one of the most popular faraday pouches in the UK, which is the perfect size for putting keys in. It’s flexible and relatively small, so portability isn’t an issue. These are under £10 and sold by a wide range of retailers. Secured by design doesn’t have to be expensive!

Key Shield KS1 – Best Larger Faraday Pouch

The Disklabs Key Shield KS1 was the first RF blocking product to gain the ‘Police Preferred Specification’ accreditation in 2018. Ever since, they have continued to make this pouch in the UK, which is brilliant. It’s constructed using military grade waterproof resistant fabric.
The Key Shield KS1 is more expensive, but at around the £30 range for a faraday pouch designed and made in the UK, I think it’s a great option.

This is the best option for a more premium police approved faraday pouch in my opinion.

Disklabs Key Shield Home – Best For Multiple Car Keys

The Disklabs Key Shield Home is the larger sibling of the KS1. This pouch is considerably larger than most of the other police approved faraday pouches on the market, making it ideal if you have two keyless cars in your household, or other things you would like to protect.

It isn’t as portable as the KS1 or Defender, so this is more suited for use as a storage space within the home. It’s the most expensive of the three I’ve reviewed, but if this saves you from needing to buy multiple individual pouches then it definitely makes sense. As with the KS1 it’s made in the UK, which I support. At 16cm wide and 26cm tall it’s plenty big enough for a whole family’s worth of keys.

If you have quite a few keys you need to protect, this is a great pick.

Do Non-Police Approved Faraday Pouches Work?

Many faraday pouches which do not have the “secured by design” accreditation still do a great job, but you are running more of a risk when purchasing one of these than sticking with one which is actually accredited as being police approved, because this ensures it has undergone strict testing and quality control measures.

This might be a route to consider if you are on more of a budget or looking for a more stylish, leather faraday pouch but I personally find it harder to recommend a security product of this nature which doesn’t have the award. If you’re considering other options purely for the sake of style over substance, I would highly recommend you take a look at the SBD database first and see if the signal blocker you’re considering is on there.

Where Can I Buy A Police Approved Faraday Pouch?

Many of the above police approved faraday pouches can be bought from a range of online retailers. I have found that Amazon stocks a majority of them and at reasonable prices. Another solid option is eBay, but make sure that they are being sold by reputable sellers as there are definitely some with mixed reviews.

Some of the manufacturers on the SBD database do also directly supply to consumers.

Conclusion – The Best Police Approved Signal Blocking Pouch Is The Key Shield KS1.

Although it’s a little more expensive, the Key Shield KS1 is well worth the money. As the first officially recognised faraday pouch, it’s had a lot of thought put into it’s design. Speaking of which, The KS1 was designed and manufactured in the UK, and continues to be manufactured locally in the UK to this day.

If you’re on more of a budget, the Defender Signal Blocker is still a very solid option. It’s probably (from anecdotal evidence) the most popular faraday pouch in the UK, or certainly one of the best selling ones at least.

Relay theft is becoming more and more well known to both the public and criminals, so protecting your keyless entry car, especially in the UK, should be a top priority.
