Review on VONETTI Shield Premium Keyless Protection by Brian Wersching

Okay, it's a bit bulky for your pocket, but should fit in your wallet. This works very well. Stand next to a car with the key fob inside and the lid closed and the car will absolutely not open. It is enough to remove the cover and the machine will open normally. This should prevent hackers from getting into your car by duplicating the fob signal while the key is inside and the lid is closed. Well done - MUCH better than bags that will rub through a layer of metal foil (and you won't notice) and stop working. Yes, it's a little unwieldy and takes away some convenience - but all good security is a little impractical.
