Review on DDSKEY Faraday Car Key Signal Blocker Box - RFID Signal Blocker Pouch for Car Keys with Single Lock by David Causillas

Revainrating 5 out of 5

Really works 100%! A+

This box works like a Faraday box. Blocks 100% of the RF signal. I put the keys in the box, closed the lid and tried to open the machine with the box right next to it (6 inches away) but the patch would not open. I opened the lid and the machine opened up. Excellent box for such a price, it works 100%. Thanks very much!
