Defender Signal Blocking Pouch RFID - Phone Case Signal Blocking Device - Car Key Signal Blocker Pouch Security Case - Signal Blocking Wallet For Car Keys Mobile Phone Cards - Grey 2 x Pack

Arrived promptly and packaged well.I bought these as I'm collecting a desirable new car with keyless entry in a few weeks and wanted some extra protection.The pouch has a handy notice telling you where to put the keys for blocking which is good to know as there are two pouches.These fit my current car keys along with all the keyrings attached to them perfectly and it isn't a tight fit.Curious to try the blocking, I put my phone in the pouch and closed the top and asked my partner to call me... Straight to answerphone, no dial tone! Took my phone out the pouch and could see that all connections were switched off - no signal, no 4G or WiFi. So far so good!I will update this once I have my new car to check the keys.UPDATE - Well worth buying, cannot open the car with the keys in the pouch.

Have been using these signal blocking pouches on a daily basis for the past couple of years - immediately tested when delivered by standing right next to the car and when sitting inside and they worked perfectly fine.BUT after randomly testing them again after >2 years I was mortified that I was able to unlock my car when standing next to it when the keys were still within the pouch. After reading a few other reviews on here, it appears they (somehow) lose their ability to block the signal (maybe due to material after some use) so I was disappointed to say the least.Impossible to know how long they actually worked for and no option to return or request replacement. As a result, I’ve decided to upgrade to a box alternative instead.

Updated 6th Feb:After contacting the seller and explaining the issues, without any quibbles they sent me two new ones which I received today. Thank you very much!When these arrived I was very impressed by the quality and their ability to block the signals to and from my car key fob. Sadly after 3 months the stitching on the stitching has failed on velcro part on the body, and not sure if this is the reason why the signals are no longer blocked as I can open my car with the keys inside and start the engine. Luckily I bought two so now using the other one, but still not good that one only lasted around 3 months of daily use.

Having tried this out while even sitting in the drivers seat - it works, perfectly!... and that’s all that matters to me. I ordered the one that holds and blocks smartphones as well which I find I don’t really use, consequently the pouch is a bit too big. So my advice is that if you want a reliable and trusted method of blocking your car keys signal then this does the job but go for the same but smaller pouch which is intended for a car key only that way it’s small enough to put in your pocket.

Works OK so far for my car key but the metallised foil lining seems quite flimsy and I am not sure how well it will stand up to anything with a slightly rough edge. I guess once the lining splits, protection is gone. I already removed an accessory key from my car key ring to hopefully prevent this. Pouch is a bit large for a jacket pocket, but I knew that when I bought it from the dimensions quoted!

Bought two just under 3 months ago and initially they worked great. Unfortunately the stitching has started to come away on one side and I can now unlock the car while the key is in the bag. I have the spare key in the other bag so I really need to have two working ones. Others do seem to have the same problem. Good price but you get what you pay for.

My son took my car out to visit a friend. After starting the car he replaced the keys back in the pouch and proceeded to reverse off the drive. As he got to the top of the driveway, the car switched off...! He didn’t realise that the key should be in the pouch when not in use...LolAt least I now know it works... thank you.

I've had this product for over a month now and thought I would review it i was told by testers it was the cheapest and best on the market well after using it on a daily basis and testing it myself yesterday I can say its still working ppl who say it doesn't after say a week are not using it properly under the lip there are two pouches i use the back pouch wether the front one does not protect I dont know have not tried it and you get two one for your spare keys thumbs up from me 👍👍
