Do Faraday wallets really work to stop keyless theft?
I have a new keyless entry car. On a dealer's recommendation, I bought an RFID wallet which is supposed to block the radio signals. However, I can unlock the car with the key in the pouch in my pocket. But wrapping the key in a single layer of aluminium foil is effective. So I tested my neighbours RFID wallet - different make but the same result. I conclude that they do not block the radio signals and so are as good as useless. Are all such wallets the same?
