Description
Rear tailgate lock for Citroën and Peugeot vehicles
Product Overview
This rear tailgate lock is designed for a range of Citroën and Peugeot models and replaces the original latch mechanism that secures and releases the tailgate / liftgate. It integrates the mechanical latch and the electrical actuator interface used by the central locking system. The part is commonly searched for by product codes and reference numbers listed below.
Function and Application
The tailgate lock secures the rear hatch in the closed position and works with the central locking and remote release systems. When you operate the remote or interior switch, the actuator releases the latch allowing the tailgate to open. A correctly functioning lock is essential for vehicle security, water tightness of the luggage compartment and proper operation of the tailgate struts.

Recommended Installation
Suitable for experienced DIYers and professional mechanics. Basic replacement steps:
- Open the tailgate and support it securely (use a helper or prop rods) to avoid injury.
- Remove the interior tailgate trim panel to access the lock assembly—carefully release plastic clips to avoid damage.
- Disconnect the electrical connector and any linkage or cables attached to the lock (note their routing for reassembly).
- Unbolt the old lock from the tailgate and remove it from the carrier plate or mounting points.
- Install the new lock in the reverse order: secure fasteners to the correct torque, reconnect linkages and the electrical connector, and refit the trim panel.
- Verify operation: lock/unlock with remote and interior switch, check manual opening, and confirm the tailgate closes and latches securely.
Always follow manufacturer procedures and safety practices. Disconnect the battery before working on electrical connectors to reduce the risk of short circuits or accidental actuator activation.
Why This Part Commonly Fails
- Wear And Tear: Moving components and plastic parts are subject to mechanical wear over years of use.
- Corrosion And Dirt: Moisture or road salt can corrode metal parts and lead to sticking or seized mechanisms.
- Actuator Failure: The small electric actuator or its internal gears can fail electrically or mechanically, causing intermittent or complete loss of function.
- Mechanical Damage: Impact to the tailgate, improper closing or misalignment can deform the latch or mounting points.
Typical Service Life
Service life depends on mileage, environment and maintenance. In normal conditions many locks last several years, but coastal environments or heavy use can shorten lifespan. Inspect the mechanism during routine service if you notice slow or noisy operation, intermittent locking, or water ingress into the luggage compartment.
Search And Compatibility Notes
Customers often search by product numbers (9684648680, 9804762080, 8719F8). Ensure the listed codes match the reference on your original part before ordering. The lock fits multiple Citroën and Peugeot models indicated above; confirm fitment by matching part numbers and physical appearance.
Recommended Tools
Trim removal tools, torx/socket set, screwdriver set, torque wrench (if specified by manufacturer), and protective gloves. A second person to support the tailgate during removal/replacement is helpful.
Note For Professionals
When replacing the lock as part of a vehicle repair, check associated items such as striker alignment, tailgate hinges and seals. Correct alignment and functioning of the striker plate avoids premature wear of the new lock.
