DEFENDER SIGNAL BLOCKER MINI

Bought these after reviewing several different brands. They are an ideal size for the keys to my new Astra Tourer and work as the key signal is blocked till you start removing the key from the pouch. They easily fit in your pocket as well.

I live in Birmingham and when I brought a new car and found out it had keyless entry I ordered these the night before. Small and discreet and hides the key away. The pouch is well made and has worked well blocking the signal completely even when stood next to car or inside, really does its job well! A must for any keyless car owner! For this price why wouldn’t you.

Update 14/02/2023: I downgraded from 5 stars to 4 stars. After 2 months, the Defender pouch I was using every day had begun to leak signal. I spoke to Solon Security to confirm the length of the warranty, and is 12 months. I then spoke to Amazon, who agreed to refund the full amount of the transaction (even though the 2nd pouch still worked correctly). I then purchased another pair of Defender Car Key RFID Signal Blocking Faraday Pouches from Amazon. I will continue using the 3 pouches and will update this review again in August or September 2023. Update 05/11/2023: The second pouch failed after 5 months of use. So it seems that you only get a few months use out of each pouch before the signal starts leaking. I have been reading up on this and apparently it is normal, due the material and stitching gradually degrading over time. So even though the warranty is 1 year, I feel that it is still excellent value for the price. So I will keep this product at 4 stars because I have got 7 months of signal blocking for only £4.95. ========================================= These Defender pouches are manufactured by Solon Security Ltd and are accredited as meeting the Police Preferred Specification by Secured By Design, (the official police security initiative that is owned by the UK Police Service). I bought a pair of these for just £4.95, which I think is incredibly good value. Each pouch has an attached key ring for you to attach your car fob, so that they always remain together The pouch totally blocks the radio-frequency identification (RFID) when the key fob is fully within the signal blocking faraday pocket. I know this, as I am unable to lock or unlock the car when the fob is completely inside the pouch. Nor am I able to start the ignition with fob inside the pouch. This is a great device that stops potential thieves from being able to relay the signal from your key fob, to steal your vehicle when you are not nearby. I bought a pair, so that I have one for my main car key fob, and another for my spare fob. The spare fob is obviously kept securely inside the Defender pouch at all times, which is then tucked away in a drawer back home. I also have a third RFID faraday pouch (bought separately) that I keep inside the glovebox. At £4.95 a pair, each pouch costs only £2.48 and will not last forever (as stated by other users in a few reviews). I keep the spare in the glovebox just in case the Defender pouch I am using starts to leak signal, so I can then switch over pouches, thus keeping my car as safe as possible. Like I said, this is a great product at an incredibly low price. Thoroughly recommended.

Quality product use it every day

This is my second review of Defender Signal Blocker Mini 2 Pack pouches. I initially purchased this product in April 2024 and they failed within a year of use. I purchased the same product again in April 2025 and they failed after 9 months of use. It is only good luck that I have two cars still on the driveway. I urge anyone who has purchased this product to go outside with the key secured in the Defender pouch and try to open your vehicle. The manufacture needs to investigate why these fail within a year of use and improve the product. Therefore, in my experience, if you don’t want your car(s) stolen, don’t buy these pouches.

The good news is it definitely works. You get 2 pouches ,one for the spare. It's compact so I suppose you can get your car key in plus your door key and a couple of £20 notes. A bit fiddly to get your key out but it needs to be a tight fit to work

We did get two from Halfords but they didn’t last very long “in fact they only lasted abut a month “so we have now got these from you & so far they are working very good .

These worked for a few months but after that wouldn't block the signal. Car unlocked even though key was contained inside with the flap closed. I wouldn't recommend these as had others which work better and last much longer.
