Do I need to screen my keyless car key when I'm at home?
If a key has a button to open the car door and you press a different button to start the car, do you need to screen the key when at home?
The metal within the wallet should act as a Faraday bag, effectively doing the same job as the aluminium foil - which suggests there's an issue with the bag sealing. We've tested the Monojoy faraday bag on multiple keyless entry cars and it's always worked flawlessly, but the wallets/bags don't block signal if there's any kind of opening. Therefore, if the velcro isn't fully closed up, or there's a hole on the metal interior layer, or the key is put inside the wrong part of the pouch (which some people do) then it doesn't work as it should.
