• Wait at least 10 minutes after battery disconnect before working near the door airbag area.
• Keep the ignition off while unplugging door connectors.
• Support the door trim panel so it does not hang by the wiring.
• Handle clips gently to avoid breakage.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the inner door trim panel

• Use a plastic pry tool set and trim panel removal tool (specialty) to pop out the trim caps, switch bezel, and hidden fasteners.
• Use a 7mm socket or Torx T20 screwdriver to remove the visible panel screws, if equipped.
• Lift the panel straight up to release it from the window ledge.
• Disconnect the electrical connectors for the window switch, speaker, and any ambient lighting or puddle lamp.

Step 2: Remove the moisture barrier

• Peel back the plastic vapor barrier carefully with your hands.
• Do not tear it. You will need it sealed again during assembly.
• Keep the sticky edge clean.

Step 3: Access the latch and actuator

• Use a Torx T30 screwdriver to remove the screws holding the latch/actuator assembly at the rear edge of the door.
• Support the latch while removing the last screw so it does not drop inside the door.
• Reach through the access opening and disconnect the latch rods and electrical connector.

Step 4: Remove the latch/actuator assembly

• Use needle-nose pliers to release any rod retainers.
• Slide the latch/actuator assembly out through the access opening in the door.
• If it binds, rotate it slowly until it clears the inner door structure.
• Torque on removal fasteners: note orientation for reassembly; final torque will be set on installation.

Step 5: Install the new latch/actuator assembly

• Slide the new assembly into the door in the same orientation as the old unit.
• Reconnect the electrical connector and latch rods.
• Make sure each rod clip fully locks into place.
• Install the latch screws using a Torx T30 screwdriver.
• Torque to factory specification.

Step 6: Test the lock before reassembly

• Reconnect the battery temporarily if needed for testing.
• Use the key fob, interior lock switch, and mechanical key to confirm the latch locks and unlocks.
• Check that the inside and outside handles open the door correctly.
• If the latch does not move, recheck the connector and rod clips before closing the door.

Step 7: Reinstall the moisture barrier and trim panel

• Press the vapor barrier back into place and seal the edges.
• Reconnect all trim panel electrical connectors.
• Hang the panel on the window ledge, then press the clips back into the door.
• Reinstall all screws using the 7mm socket or Torx T20 screwdriver.
• Torque to factory specification.
