blocks signals to keys and phones neat small size for a handbag

Excellent for keeping my cars safe

Why did you choose this product over others?:I bought a pair of these in 2019 and have happily used them until now (2025) when I discovered that one of them was no longer blocking the signal. It’s a good idea to check them regularly to ensure your car is really safe.Size:It’s quite a roomy pouch which I like compared to others which feel too small.Quality:Overall a good product but just check it every so often to ensure it still works as it should.

Much larger than they look but work very well. Will accommodate any type of key fob.

This Defender signal blocker does exactly what it promises. As soon as I put my car key inside, it completely blocks the signal — I tested it by trying to unlock the car, and nothing happened until I removed it. The pouch feels high quality and well-made, with a strong closure to keep everything secure. It’s compact enough to fit in a bag or pocket but still feels sturdy. Great for peace of mind and protecting against keyless car theft. Highly recommend!

Excellent purchase, the pouches really work and are a great security measure at a low price, they should last for ages too.

It is very big and suitable for a phone rather than my needs which is for one key fob, but it is well made and suits the purpose.

This works for a few months… until it fails. Please regularly check your pouch otherwise there will be a day where it fails.
