Hi , sorry another noob question .
The key battery is low and I only have one key from the dealers at the moment .
I know there are YouTube videos on how to change the battery out but what happens if it is not recognised when done - is it easy to re-sync ?
When I bought the car the ignition wouldn’t start so the dealer put the key in a specific place but I couldn’t see where - can anyone explain where this is ?
Sorry for the dumb questions - I don’t want to get this wrong as I have no backup key .
