Description
Overview
High-quality Right Front Door Lock for Citroën C4 designed for the passenger-side of 5-door models. This unit replaces the central locking mechanism for the front right door and is identified by multiple OEM references for fast matching during repairs or parts lookup. Ideal for professional workshops and competent DIY mechanics.
Function And Application
This component is the central locking actuator/lock assembly for the right front door. It controls mechanical latching and remote central-locking actuation, integrating with the vehicle’s door latch and electrical locking system. It is fitted to the passenger-side front door in Citroën C4 5-door configurations and is used where the original OE references match.
Common Failure Modes
Door locks may fail due to prolonged mechanical wear, moisture ingress and corrosion, broken internal gears or plastic parts, and electrical faults such as a faulty actuator motor or connector corrosion. Symptoms include a door that won’t lock/unlock with the remote, intermittent operation, or a rattling noise from the door when operating locks.
Replacement And Installation Notes
Installation is a medium-difficulty job suitable for experienced DIYers and professional technicians. Typical steps:
- Disconnect the negative battery terminal to avoid short circuits and prevent unintended airbag deployment.
- Remove the interior door trim panel and any moisture barriers carefully to access the lock assembly.
- Disconnect electrical connectors and linkages (interior handle and child lock rod) from the lock unit.
- Unbolt the lock/actuator assembly from the door and extract the unit through the access opening.
- Fit the new lock assembly, reconnect electrical plugs and linkages, test operation before refitting trim, and verify central locking and manual operation.
Recommended tools: Torx/hex/Phillips drivers, trim tools, socket set and multimeter for electrical checks. Inspect door wiring and connectors for corrosion while replacing the unit, and lubricate latch points with an appropriate grease to extend service life.
