Hi. I just picked up a 2016 A6 but it only came with 1 key. The dealer is getting a second one ordered. The door handles have the little rectangle but I can't open the doors without using the key to remotely open. Should this be working seeing as the rectangle thingy is on the handles and if so, could it be that it only works with a main key and maybe what I have right now is the spare key and keyless entry doesn't work? I just want to check before contacting the dealer again. Thanks
