How to Remove the Rear Lock on Mercedes C-Class W203?

Model: Mercedes Classe C W203 - Years 2000-2007
Part: Door lock

In the attached video, we can see how to remove the rear door lock of the Mercedes C-Class W203. First, we need to remove the inner door panel, then disconnect the lock connector and remove the plastic clips that hold the cable in place. Be careful not to damage the clips, as we will need to reuse them later. Now, remove the 3 Torx screws that secure the lock using a T30 Torx wrench, and then the single screw that holds the foam piece inside the door. Now we can extract the lock unit and replace it, remembering to attach the bracket before installing it, as shown in the video.
