Have manage to program a transponder on a Q7 with VVDI2 xhorse, but for the remote to work must be a dealer key , otherwise remote will not work
you need a chip on board key for the remote to work as the remote codes in with transponder. There is no separate remote coding procedure on these 8E systems. There are a lot of Chinese keys with separate remote board and transponder chip.. these are useless, the chip will start the car but the remote will never work!
so it’s dealer key then?
a dealer key is a pre coded key from the factory ordered by a dealer to a vehicle vin number. You do not need a dealer key you just need to make sure you are buying the correct ‘all in one’ key from your supplier and not the Chinese keys with separate remote board and transponder chip.
