🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a flat trim panel tool to pop off the small trim covers in the door pull and handle area.
• Use a 7mm socket to remove the screws holding the door panel.
• Use the trim panel tool to release the plastic clips around the edge of the panel.
• Lift the panel straight up to unhook it from the window ledge.
• Work slowly to avoid broken clips.

Step 2: Disconnect electrical connectors

• Use your hands and a small pick tool if needed to release the wiring connectors for the window switch and speaker.
• Set the door panel aside on a clean surface.

Step 3: Remove the moisture barrier

• Carefully peel back the plastic vapor barrier.
• If the adhesive is torn, clean it and apply door vapor barrier adhesive during reassembly.
• Keep the barrier intact if possible.

Step 4: Disconnect the actuator linkages

• Locate the latch and actuator assembly inside the door.
• Use a small pick tool to release the lock rod retainers and linkage clips.
• Use needle-nose pliers if a clip is tight or hard to reach.

Step 5: Remove the door latch and actuator assembly

• Use a Torx T30 screwdriver to remove the latch mounting fasteners on the door edge.
• Use a 10mm socket with a short extension if any lower bracket fasteners are fitted.
• Slide the latch and actuator assembly out through the access opening in the door.

Step 6: Transfer any parts if needed

• If your replacement part does not include all clips or rods, transfer them one at a time from the old unit.
• Make sure every linkage clip snaps fully into place.

Step 7: Install the new actuator assembly

• Feed the new actuator and latch assembly into the door the same way the old one came out.
• Reconnect the rods and clips first, then install the mounting screws.
• Use a Torx T30 screwdriver to tighten the fasteners.
• Torque to 8 Nm (71 in-lbs) unless your replacement latch kit specifies otherwise.

Step 8: Reconnect wiring and test before reassembly

• Reconnect the actuator electrical connector.
• Reconnect the battery negative cable with a 10mm socket.
• Test the lock and unlock operation with the key fob and the interior switch.
• Make sure the door handle, lock button, and key cylinder all operate smoothly.

Step 9: Reassemble the door

• Reinstall the vapor barrier and press the adhesive down firmly.
• Reconnect the door panel wiring connectors.
• Hook the top of the panel onto the window ledge, then align the clips.
• Press around the edges to snap the panel into place.
• Install the screws with a 7mm socket.
