Description
Electric central locking latch for right front door for Citroën C4 5‑door first series — passenger door.
This electric door lock is a direct-fit replacement for the right front (passenger) door of the Citroën C4 5‑door first generation. Ideal for professional workshops and DIY mechanics, the unit restores reliable central locking operation and is commonly searched by its part numbers, increasing findability for customers looking for 9686719780, 9683415980 or 9136ES. The mechanism integrates the latch and electric actuator to receive locking commands from the vehicle’s central locking system and physically secure the door striker.
Function And Fitment
The unit operates as the electromechanical interface between the door striker and the central locking system. When commanded by the car’s locking module, the actuator moves internal linkages that engage or release the latch. This part fits the Citroën C4 First Generation 5‑door hatchback (passenger front door) and is intended as an OEM‑style replacement. Use the product codes when searching to ensure correct match.
Installation Recommendations
Replacement is straightforward for a technician familiar with door trim removal. Typical steps:
- Remove the inner door trim and moisture barrier to access the latch unit.
- Disconnect the electrical connector and unclip any lock rods/linkages (note clip positions).
- Unbolt the latch from the door shell and withdraw the unit.
- Install the new latch, reconnect rods and electrical plug, and loosely fit bolts to adjust striker alignment before final torquing.
- Test central locking and manual operation several times, then reassemble door trim and barrier.
Recommended Tools: Torx and metric sockets, trim tools, needle‑nose pliers for clips, and dielectric grease for connectors. For safety and to avoid electrical shorts, disconnect the negative battery terminal before disconnecting electrical connectors or working near powered circuits.
Common Failure Causes
Door locks typically last many years but can fail due to:
- Wear of plastic gears or internal components inside the actuator leading to intermittent or no movement.
- Corrosion and water ingress, especially if the door moisture barrier is damaged, causing sticking or electrical faults.
- Broken or fatigued linkage rods and retaining clips preventing full latch engagement.
- Impact damage from collisions or slamming that bends the striker or damages the latch housing.
- Electrical connector corrosion or wiring faults causing loss of power to the actuator.
Typical symptoms: Door fails to lock/unlock with remote or central command, requires manual operation, makes grinding or clicking noises, or does not hold closed properly.

Why Replace Rather Than Repair
While some latch faults can be traced to linkage clips or wiring and repaired, internal actuator or gear damage usually requires a full unit replacement to restore reliable operation. Installing a new OEM‑equivalent latch avoids repeated workshop visits and ensures correct alignment with the door striker.
