Description
Rear tailgate lock for Citroën and Peugeot vehicles.
This rear tailgate lock (tailgate latch) is a direct-fit replacement designed for a range of Citroën and Peugeot models. Suitable for professional workshops and experienced DIY mechanics, the unit restores secure closing and reliable central-locking operation of the liftgate. The part is frequently searched by OE numbers, so check the product codes listed below when matching parts for repair or replacement.
Description And Function
The tailgate lock secures the rear hatch and interfaces with the central locking system, mechanical striker and the tailgate release (handle/remote). Depending on the version, the assembly contains a mechanical latch, an electric actuator and an electrical connector for integration with the vehicle’s locking system. A correctly functioning lock ensures the tailgate remains closed under driving loads and allows reliable opening via key, remote control or interior release.
How Replacement Is Performed
- Remove interior tailgate trim to access the lock assembly; hold clips and screws carefully to avoid damage.
- Disconnect the electrical connector(s) for the actuator and any switch(es).
- Unbolt the lock unit from the tailgate (usually 2–3 fasteners depending on model) and free the mechanical linkage from the latch if present.
- Fit the new lock, reconnect linkages and electrical connector, then test the latch operation several times (manual and remote) before reassembling trim.
- Check striker alignment and tailgate closing force; adjust hinges/striker if needed to ensure smooth engagement and full locking.
Common Symptoms Indicating Failure
- Tailgate fails to lock or unlock with remote or central locking.
- Tailgate must be slammed to engage latch or remains rattling while driving.
- Intermittent operation of electric release or complete absence of response from tailgate actuator.
- Visible corrosion, broken plastic parts or seized mechanism inside the latch housing.
Why The Part Most Often Fails
Failures are usually caused by water ingress and corrosion, wear of mechanical components, broken plastic levers or degraded actuator motors after many cycles. Misalignment of the tailgate or a damaged striker can overload the latch and accelerate wear. Dirt and lack of lubrication also contribute to binding and intermittent operation.

Mounting Recommendations
- Disconnect the negative battery terminal before working on electrical connectors to avoid short circuits and accidental central-locking activation.
- Handle interior trim and clips with care to prevent breakage; use proper trim tools.
- Before final reassembly, verify full mechanical engagement and electrical operation of the new lock (lock/unlock with key, remote and interior switch).
- Use light, appropriate lubrication on moving metal-to-metal contact points (silicone spray or light grease recommended); avoid heavy greases on electrical contacts or catch surfaces.
- If the tailgate remains misaligned after replacement, adjust hinges/striker to prevent premature wear of the new latch.
Notes For Professionals And DIYers
This part is intended for technicians and competent DIY mechanics familiar with vehicle‑body trim removal and basic electrical disconnection. Always verify fitment by OE numbers where possible. After installation, perform several open/close cycles and a road test to confirm correct operation and absence of rattles.
