X3 E83 LCI (2006-2910)
The keys work to start the car, but there are no remote features, and I guess the batteries are dead. The seller gave us two original keys, a valet key, and two new blanks. I tried to program the blanks as remotes. I watched videos about changing the batteries, and those are the old “E3?” keys that aren’t meant to have batteries changed.
The boy is happy. It’s his first car.
But I’m wondering how big of an expense fixing this will be. I wonder if going to the dealer is the right route.
