Hi, I recentley bought an audi a3 3dr 1.6 from my local garage, everything was fine until a couple days after i tried to open my boot with the key i was given,(i was given 1 key only as this is how the garage had recieved it) but the key did not fit the lock, so i tried to open my glove compartment lock, still the key did not fit. the key only fits the ignition and the driver door lock, as it is a 3 door the driver door only has a key hole lock. the car also has an alarm so whenever it sounds i have to open the door put the key in the ignition and turn the key half way to stop it, as the key is just a normal manual key and not an electronic one. I have told my dealer and he said there was nothing he could do about it, i rang my local Audi dealer and they said there could be a possibilty that the barral could have been changed along with the driver door lock to which the key only fits to. what should i do now? should i get all the locks changed and let the my local garage take the bill or is there any other suggestions??? i would appreiciate it very much if someone could help with this. thanks.
