Hey all! We've got a B6 Passat wagon, and suddenly my partner has been locked out! She managed to get in using the emergency little key thing that hides inside the fob, and the car started and off she went.

She can lock the car with the remote just fine, it simply wont unlock - not will the trunk button work! The light on the remote lights up for all buttons, and given it is able to lock the car I don't think it's an issue with the fob or battery.

What's happening here? Could the remote have lost it's programming with the car, but still have kept the locking mechanism? I haven't been able to try with my fob yet as I'm at work.
