First my driver side door lock, turns without any tension rendering the lock/unlock feature useless. I have to lock or ublock the doors using either the trunk or passenger side. I just tried to get into my trunk, and although it activates the central locking system, I can't open my trunk. Any thoughts on what might be wrong?

Thanks in advance

Make sure you are turning the key all the way to the left, and then push in while holding it to the left. This should manually open the truck.

The drivers door problem sounds like the metal extension on the backside of the tumber either broke or fell off. Common.
