After much thought about your locks, because it is not very often I get defeated, did they ever work? The last couple of 3's I had in the shop had different fob's. The one for my 6 looks like the one you have? Made me wonder if you got the wrong fob with the car. I haven't played with any of the spare fob's I have laying around in my box to see if they all communicate with different year and model. Just a thought.
