- Lower or position the window as required to gain access to lock mounting screws and linkages.
- Disconnect the electrical connector to the actuator and unclip any mechanical linkages (door handle, lock rods) from the latch.
- Remove the fixings securing the lock assembly, extract the old unit and install the new lock in the reverse order. Ensure linkages are routed and attached without binding.
- Reconnect the battery and test central locking, remote operation and manual opening/closing before refitting the door trim.
- After installation, check for smooth locking/unlocking and correct door alignment. Replace any damaged clips or seals to avoid water ingress.

- Mechanical Stress Or Impact: Door slams, misaligned windows or broken linkages can place extra load on the latch and actuator.
- Connector And Wiring Issues: Corroded or loose connectors lead to poor power supply and erratic operation.
- Age And Mileage: High-mileage vehicles or cars operating in harsh climates tend to experience earlier failures.
