Just recently purchased a 2001 330CI. It is not a convertible. The key fob will not unlock the door. I can hear it try to cycle, and the interior lights come on, but the door does not unlock. This is happening on both doors, but the fuel door unlocks with no problem. The Key fob will lock the doors and open the trunk with no problems. The center console button is not working either. I can hear the fuse clicking when i press it, but that is all. To unlock the passenger side door, I have to repeatedly press the button in the cabin and pull on the handle from the inside and sometimes even this does not help. If it is the actuators, is it going to be a tough fix???
