A working Faraday pouch should not be recognized by the car even when right alongside. Normal operation of the fob is to be non effective at around 5 ft.
Agree, a working faraday pouch should not be recognised by the car irrespective of the distance from the vehicle. I can stand touching my Sportage with the key in the pouch and I am unable to open the doors until the key is removed. Please be aware as previously mention the effectiveness of the pouch deteriorates over time and you should renew them on a regular basis. Just keep checking with the key inside and you will soon find out when to replace.
