No, the immo chip is hard coded to your vin & brand, so dont waste your time with used, trust me after many days months investigating, but new ones from audi are fairly cheap about £50 whereas old ones were hell of alot more & coding is 10-20 mins work at most, so £100 for new key/s at a dealer is fair price, check this thread:
