Installation
Replacement normally requires removal of the inner door trim to access the lock mechanism. Typical steps: remove door panel and trim clips, disconnect electrical connectors and locking rods, unscrew the lock unit, install the new lock and reconnect linkages. Ignition barrel replacement usually involves removing the steering column shrouds to access the barrel and electrical connectors. Follow vehicle-specific repair manual and take precautions with airbag and steering column components. Professional installation is recommended for immobiliser reprogramming.
Common Causes Of Failure
Mechanical wear of tumblers, corrosion from moisture ingress, broken linkage rods or seized components are common reasons for lock failure. Symptoms include a sticking or turning key, difficulty locking/unlocking, or intermittent central locking operation.
Durability And Maintenance
Service life depends on use and environment. Regular lubrication of the lock cylinder and protecting door seals from water intrusion can prolong life. Replace the assembly if mechanical issues persist or if the lock no longer operates reliably.
