Function & Features
The lock assembly performs two primary roles: it secures the door by engaging the striker and it houses the central locking actuator motor that locks/unlocks the door under electrical control. The unit connects to the vehicle wiring harness and interfaces with mechanical linkage rods to operate the latch.
Common Faults And Lifespan
Typical failure modes include mechanical wear of latch components, broken or detached linkage rods, water ingress causing corrosion, and actuator motor or electrical connector faults. Symptoms are difficulty closing the door, intermittent or failed locking/unlocking, and abnormal noises from the latch. Service or replacement is recommended once functional faults are identified.
Fitting Instructions (General Guidance)
- Remove the inner door trim to access the lock assembly and disconnect the electrical connector.
- Detach any linkage rods and remove the fasteners securing the latch to the door shell.
- Withdraw the old lock, fit the new unit in the same orientation and reattach linkage rods and fasteners securely.
- Reconnect the electrical connector and test central locking and manual operation before reassembling the door trim.
