Installation recommendations

Generally/typically for an electric door lock, the exact procedure may vary depending on the specific design of the door and the vehicle’s equipment.

1) Before assembly

• Compare codes 52229880 / 9135P5 with the old part and check the design match.
• Check that the connector has 6 pins and is of the same shape and locking.
• Check the condition of the lock mechanics: free movement, no cracks in the plastic, no damaged pulls/handles.
• Check the contacts in the connector (they must not be squeezed, oxidized or bent).

2) Necessary tools and materials

• Basic set of screwdrivers and bits (according to the used connecting material)
• Plastic pry bar for removing door trim
• Pliers (for clips/pulls depending on design)
• Electrical contact cleaner (optional)
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery (for electricity and risk of short circuit).
2. Remove the interior door trim and loosen the fasteners carefully to avoid breaking the clips.
3. Remove/slide the cover film or door panel to access the lock and connectors.
4. Disconnect the electrical connector of the lock and check that the pins are not dirty or oxidized.
5. Release the mechanical connections (rods/cables) according to the design – make an order or a photo for correct reassembly.
6. Unfasten the lock in the door and remove the lock (watch out for wiring and sharp edges).
7. Insert the new (used) lock in the same position, fit and fasten it.
8. Connect the tie rods/cables and verify that nothing is crossing and the mechanism is free-running.
9. Connect the electrical connector (must click firmly).
10. Before fully assembling the door, check the basic function (mechanically with a handle/control depending on the equipment – without violence).
11. Return the cover film/door panel to its original position and make sure it fits correctly to minimize the risk of moisture ingress.
12. Fit the door trim, fasten all clips and screws.
• 4) Post-assembly checks and test drive/function verification
  • Connect the battery and test locking/unlocking (centrally and locally) and correct door response.
  • Verify that the door closes properly and that the lock moves between positions without snagging.
  • Check that there is no sound when the door is folded (loose rod, badly attached connector).

  5) The most common assembly mistakes + how to avoid them

  • Conversion of design/connector → always compare the codes and 6pin connector with the old part.
  • Poorly engaged connector → the lock then works intermittently; after connecting, gently check the arrest.
  • Incorrectly guided drawbar/rope guide → stiff control or non-functioning handle; photo documentation before disassembly will help.
  • Damage to upholstery clips → use a plastic pry bar and do not pull the panel with force.

  Reasons why the part is damaged

  • Wear of the lock mechanism and internal plastic parts due to frequent use.
  • Increased moisture in the door (leakage, damaged film) leading to oxidation of the contacts and malfunctions of the electric motor/actuator.
  • Mechanical stress when the door slams shut or when the handles become stiff.
  • Electrical problems in the door wiring (broken wires in the grommet), which can cause malfunctions and overloading of the lock.
