I am beginning to wish I didn't have keyless entry system. I really cannot see the point if you need to protect the key from the latest ebay product, the signal booster. I bought two Faraday pouches on ebay and was a bit dubious about their ability to block all signals. They work very well and only cost around £3.00 for the pair, delivered. If anyone buys them, please remember that they have two sections and the rear section is the signal blocker pouch.
