2000 740il remote door unlock/lock (key)
Suddenly my key will not remotely lock and unlock my doors/trunk. I found on another forum a sequence to "re-initialize" the key - tried it and it did not work. Before I go to the dealer I wanted to see if anyone has any ideas? Could the battery in the key be bad/dead? If so can the battery be replaced or should I just not mess with this and go to the dealer?
TIA
George
