Description
This electric central locking door lock is intended for the left front (driver side) door of the Citroën C4 5-door. It functions as the lock/latch assembly with integrated actuator that receives lock/unlock commands from the vehicle’s central locking system and remote key. The unit is commonly referred to by the PSA part numbers listed below and is a direct fit replacement for compatible models.
Compatibility And Function
The part is designed for Citroën C4 5-door models (driver side). It operates the door latch and central locking mechanism, allowing remote and interior locking/unlocking, and engages the mechanical latch when the door is closed. Typical symptoms of a failing unit include a door that does not lock or unlock, intermittent operation, or unusual noise from the door lock area.
Installation
Replacement should be performed by a qualified technician or an experienced DIYer. General replacement steps:
- Disconnect the vehicle battery to avoid short circuits or unintended airbag deployment.
- Remove the interior door trim and any vapor barriers to access the lock assembly.
- Disconnect the electrical connector and any door lock rods or cables linked to the mechanism.
- Unbolt and remove the old lock assembly, then install the replacement, ensuring correct alignment of linkages and latch.
- Reconnect the electrical connector, test the central locking and manual operation before reassembling the door trim.
Follow the vehicle manufacturer repair manual for torque values, connector locations and any model-specific procedures.
Common Failure Causes
Typical reasons for failure include moisture ingress and corrosion, wear or breakage of internal plastic gears, seized linkage, or electrical connector faults. Regular exposure to water and dirt speeds deterioration. If failure is intermittent, check wiring and connectors before replacing the entire unit.
Notes For Buyers
Always verify compatibility by matching the part numbers with your vehicle’s original component. This unit is suitable for professionals and skilled DIY mechanics who can access the door internals. If uncertain about the correct part or installation, consult a service manual or a qualified workshop.
