Side – Door Behind Driver
Replacement right rear door lock for Citroën C3 II (A51) with original part code 9800625180. This electro-mechanical door lock assembly secures the rear door, works with the central locking system and door handle linkage, and is suitable for professional workshops and competent DIY mechanics looking for a direct-fit replacement. The part number 9800625180 is often used when searching online or ordering spare parts, ensuring quick identification.
Features And Function
The unit combines the mechanical latch and the central locking actuator to lock/unlock and hold the door closed. It receives locking commands from the vehicle wiring harness and actuates internal linkages that operate the exterior and interior door handles. Proper function is essential for occupant safety and for correct operation of central locking and child lock systems.
Installation Recommendations
- Always work in a safe, stable environment and follow basic workshop safety rules.
- Disconnect the vehicle battery before starting work on electrical components to avoid short circuits and accidental airbag deployment.
- Remove the interior door trim carefully to avoid breaking plastic clips; keep fasteners organized for reassembly.
- Disconnect the electrical connector and any mechanical rods or clips linked to handles and lock mechanisms.
- Unbolt the lock assembly, transfer any required rods, clips or gaskets from the old unit to the new one if necessary, then install the new lock and reconnect all linkages and the electrical connector.
- Check operation: lock/unlock with key fob, interior switch and exterior handle; ensure smooth movement of latch and correct alignment to striker plate.
- If resistance, misalignment or abnormal noise is present, re-check installation and door striker alignment before finalizing trim reassembly.
Most Common Failure Causes
Door locks typically fail due to a combination of age, wear and environmental exposure. Common causes include corrosion and water ingress that damage electrical actuator motors or switches, worn mechanical gears or plastic components inside the latch, broken linkage rods or clips, and impact or deformation from door damage. Intermittent failures often start as sluggish operation or occasional failure to lock/unlock, progressing to complete inoperability.
