Description
Electric central locking lock for the right front (passenger) door for Citroën C4 5‑door first series
Product Overview
This electric door lock is a direct replacement for the central locking mechanism on the right front (passenger) door of the first‑series Citroën C4 5‑door. It restores both the mechanical latch function and the electronic locking/unlocking signals used by the vehicle central locking system. Frequently searched by OE numbers, the unit is suitable for professional workshops and skilled DIY mechanics who require a reliable spare part identified by part codes.
Function
The unit provides the mechanical latch that secures the door and houses the actuator/micro‑switch assembly used by the central locking system. When activated by the remote or internal locking switch, the actuator moves the latch between locked and unlocked positions. The lock also registers door open/closed status for interior lights and safety systems via an integrated switch.

Installation Recommendations
- Disconnect the battery before starting work to avoid short circuits and protect vehicle electronics.
- Remove the interior door trim and protective vapor barrier carefully to access the lock assembly; keep fasteners and clips organized for reassembly.
- Disconnect the electrical connector and unhook the locking rods/linkages from the latch. Note the routing and clip positions to ensure correct reconnection.
- Unbolt the lock from the door and replace with the new unit. Reattach rods, connectors and test the locking/unlocking function before refitting trim.
- Apply light lubricant to the latch mechanism and dielectric grease to electrical connectors to improve longevity and prevent corrosion.
- Verify door alignment and smooth operation; adjust striker if necessary to avoid premature wear.
- If unsure about disassembly or electrical checks, seek assistance from a professional mechanic to prevent damage to door trim or wiring.
Common Failure Causes
Door locks commonly fail due to wear of internal plastic gears or the small electric motor, water ingress and corrosion, broken rods or clipped linkages, seized latch components, or failure of the integrated microswitch that signals door status. Repeated forcing of the door when misaligned or damaged striker plates accelerates mechanical wear. Regular lubrication and ensuring correct door adjustment reduce the risk of early failure.
Why Buy This Part
This replacement lock restores secure latching and reliable central locking operation for the right front door, helping to eliminate intermittent locking faults, door ajar warnings, or mechanical sticking. Use the listed OE and additional numbers to confirm compatibility in parts lists and searches.
