Faraday Box for Car Keys and RFID Blocking Card 2 Pack, Car Key Signal Blocker Box Faraday Cage, Keyless Car Theft Prevention

Solid box gives piece of mind. Good value. Very solid and heavy plenty of room for a few keys and fobs.

This box first performs well and blocks signals totally as long as it’s closed of course! With all our keyrings and key fobs on our keys we can comfortably fit 4 sets inside this. Really upscale quality appearance and nice materials used for this. I’m really happy with it great value for money

Perfect small case

I was looking for a box to contain bunches of keys and other bits and pieces that are usually in the hallway and the size of the box fits my needs perfectly. As for screening the signals between the car and the keys I have to trust the manufacturer that this works as I've no sure way of determining this.

Excellent product.

Great box and it looks good too.

Looks great and works perfectly . The box is small enough to not be intrusive but also large enough to fit at least four to five keys

The box looks good, is well made and is a good size for multiple keys or fairly large phones, an s22+ will fit in it exactly while laying flat, the longer ultra version will still fit but at an angle.I found this works ok for blocking basic RFID and it will block a mobile phone signal. For me testing with an S22+, it does NOT block wifi at all, I still had full 5ghz wifi signal on my phone when it was in the box. It does not block bluetooth either, I was able to continue listening to music on my bluetooth earphones when the phone was inside the box, it did weaken the signal a bit but was still clearly fully functional even from several meters away.
