After reading some of the threads here, I decided to buy a faraday pouch for my key fobs. Specifically, I got TICONN two pack off of Amazon. It came yesterday and I immediately popped my fob into one, left my phone in the house, and walked out into the garage. The car promptly woke up. I expected it to block the signal. Are my expectations out of whack? Should I send the TICONN back and try another brand?
