Ranpower Car Key Signal Blocker Case 2 X Faraday Pouch Bag for Keyless Entry Car Key Fob Anti Theft Guatanteed Blocks RFID/NFC/WIFI/GSM/LTE - 2 X Card Signal Blocking Protector-Black

Works perfectly well right up close to the door of a keyless entry and ignition car. Not sure what the 1-star reviewer was doing to make this not work but suggest maybe putting the key *inside* the bag and closing it.

Great item no problems

This works very well, it can be a fouter to get the key out at times.

Recommend

Excellent

Bought two of these, different colours. Feel safe to carry around.

It works fine blocks signal no problem

I hesitated for a long time about which key bag I should buy.Finally I bought this key bag.Happily, it actually blocks the signal completely.
