What are the steps for door removal and installation?

Prepare the tools, remove the plastic pins by pressing the central point, Use the prepared tools to loosen the two screws, then the door panel can be removed.

I previously tried removing a car door myself, mainly to replace the window regulator. The first step is definitely disconnecting the negative battery terminal to prevent short circuits and fires. Then open the door, remove the interior trim panel - there are screws and clips that need to be carefully pried open with small tools, being careful not to break the clips. Before disconnecting wiring harness connectors, take photos to record their positions to prevent incorrect reconnection. When loosening hinge bolts, get someone to help hold the door as two people can lift it off more steadily. Installation is the reverse process - adjust door gaps for proper alignment. My first attempt took two hours - remember to prepare some new clips as spares since old car clips tend to break easily, don't make the same mistake I did of having to redo the work. Safety first - wear anti-slip gloves and don't let the door drop on your feet.
