Have had the (nearly) new A3 for 4 weeks, and the dealers have just sent me my spare key. Nothing came with it, no instructions, no notes, nothing! So I checked out my Owners Manual about re-synchronising the key. That doesn't work. The steps are: Press the "unlock" button. Open the driver's door manually within 30 secs of step 1 above. Press either the "unlock" or "lock" button. The key should be sync'd..... HOWEVER.... By step 4 the key should've at least sync'd (given that it opens the door manually). Am I missing something here? Would appreciate any help. Cheers.
