How It Works
The unit integrates a mechanical latch with a small electric actuator motor that receives locking/unlocking commands from the vehicle’s central locking module or remote key. When actuated, the motor drives internal gears and linkages to move the latch between locked and unlocked positions, allowing the door to be secured or released.
Common Faults And Causes
- Complete failure to lock or unlock: often due to actuator motor burnout, stripped gears, or electrical disconnection.
- Intermittent operation: usually caused by corroded connectors, damaged wiring, or worn brushes inside the motor.
- Stiff or noisy operation: water ingress, dirt build-up, or mechanical wear affecting the latch mechanism.
- Failure after impact or door misalignment: physical damage to the latch or linkage can prevent proper operation.
Replacement And Installation
General replacement steps (professional or experienced DIY recommended):
- Disconnect the negative battery terminal before starting to avoid short circuits and protect vehicle electronics.
- Remove the door trim panel carefully to access the lock mechanism; take care with clips and door wiring harness routing.
- Disconnect the electrical connector and any mechanical linkages to the inner/outer handles.
- Unscrew the lock mounting fasteners and remove the defective unit from the door shell.
- Fit the replacement lock, secure mounting bolts to the original positions, reconnect linkages and the electrical connector, then reconnect the battery and test locking/unlocking before reassembling the door trim.
- Ensure correct door adjustment and lubrication of moving parts for long-term reliability.
Compatibility And Notes
Fits Citroën C4 five-door models where the OEM references match. Always verify fitment by checking the vehicle VIN or comparing OEM reference numbers (listed above). When replacing, inspect the door wiring loom and connector for corrosion or damage; replace or repair as necessary to prevent repeat faults. If unsure, consult a trained technician or dealer parts department for confirmation.
