Hi,

i did purchase the E53 4.8 is 2006 and it came with 2 keys (diamond type). I can use both to unlock the door and drive, but the remote of both are not working for the car.

I did open both keys and tested the batteries and both shows 3.10 V, i.e, the batteries are not dead.

How can i enable te remote lock / unlock / trunk open for BOTH keys?

Best regards,

Paulo
