it is a worry mate, what happened to rolling transcoding the code changed every time, first used on Cat 1 and Cat 2 security device the code changed every time so couldn't be scanned that was what it was for
so the Mfg have fitted a lower security key and a non category one alarm system that would have a transcoded immobiliser to fit a button to start the car. what was the problem with a key?
by the way mate found the pouch on amazon at a bit cheaper price
