Here we have a good used complete matching key set with bcm ecm, metric speedometer etc removed from a 2013 Audi A3 tdi with only 86,000 miles. No damage whatsoever. Should fit years 09-13 A3, S3 and maybe others but please confirm fitment with part number or vin. This should be everything you need to change to get your car running if you lost your key. I'm also parting out the rest of the car, so If you need anything please send an email so I can list it on ebay for you.
