Description
Overview
Electric left front door lock designed for Citroën C4 5-door models (driver’s side). This unit integrates the latch and central locking actuator to operate door locking/unlocking from the remote central locking system and the interior switch. It is supplied with common PSA reference numbers for fast identification during parts lookup.
Key Features
- Electric central locking mechanism and latch combined into a single assembly.
- Direct replacement for original equipment on compatible Citroën/Peugeot (PSA) models listed by part number.
- Designed for the left front (driver) door on 5-door Citroën C4 variants.
- Robust mechanical latch with integrated electrical actuator for remote and interior locking.
Fitment And Compatibility
Fits Citroën C4 5-door models on the left (driver) side. Commonly searched by part numbers and cross-references, including the main references shown below. Always verify part numbers against your vehicle VIN or parts diagram before ordering.
Installation Notes
Replacement is typically performed by a competent mechanic or experienced DIYer. Typical steps:
- Disconnect the negative battery terminal to prevent shorts when working with electrical connectors.
- Remove the inner door trim panel and protective moisture barrier to access the lock assembly.
- Unplug the electrical connector and detach any linkages from the lock mechanism (note positions for reassembly).
- Remove retaining screws/bolts, swap the old unit for the new one, then reassemble in reverse order. Verify operation of central locking and mechanical latch after installation.
Common Failure Modes
Electric door locks can fail for several reasons: wear of internal gears, seized or worn latch components, water ingress that corrodes contacts or mechanisms, and electrical faults such as broken wiring or connector issues. Symptoms include intermittent locking/unlocking, inability to lock or unlock from the remote, or the door not latching properly.
Practical Tips
- If the lock is intermittent, check door harness connectors and earth points before replacing the unit.
- Lubricate mechanical latch points with appropriate grease during reassembly to extend service life.
- When replacing, compare plug shapes and mounting points to ensure correct fitment; some PSA cross-references differ by connector or actuator orientation.
