• Plastic levers for panel removal
• Pliers for handling tie rods and clamps
• Contact cleaner and cloth
• Work lighting

3) Step-by-step assembly procedure

1. Turn off the ignition and prepare the vehicle for safe dismantling.
2. Dismantle the inner door trim so as not to damage the handles or covers.
3. Carefully move or remove the protective layers that prevent access to the lock.
4. Disconnect the electrical connector from the original lock.
5. Release the rods, cables or mechanical fasteners that are attached to the lock.
6. Unscrew the lock fastening and remove the old part.
7. Compare the old and new lock, especially the attachment, levers, connector and position of the mechanical parts.
8. Place the replacement lock in place and secure it using the original attachment method.
