Description
Electric rear tailgate lock for Citroën C4 Picasso, C5 X7 and Peugeot 207 vehicles.
Product Overview
Robust electric tailgate lock designed for secure closing and reliable central-locking integration on Citroën and Peugeot models. The unit replaces the factory latch/actuator assembly and restores proper locking, unlock actuation and tailgate alignment. Commonly searched by part numbers, this lock is suitable for workshop technicians and DIY enthusiasts who service rear hatch locking systems.
Key Features and Benefits
- Direct replacement for factory electric tailgate latch assemblies on compatible Citroën and Peugeot models.
- Integrated electric actuator and mechanical latch for complete locking function.
- Restores central locking operation and secure tailgate closure—important for safety and vehicle watertightness.
- Commonly referenced by OEM part numbers for quick lookup and ordering.
How It Works
The lock houses a mechanical latch and an electric actuator. When a lock/unlock command is received from the key fob or central locking module, the actuator moves the latch mechanism to lock or release the tailgate. The latch also includes mechanical release features for the interior handle and emergency opening.
Replacement Procedure
- Disconnect Battery: Before any electrical work, disconnect the negative terminal of the battery to avoid short circuits and accidental actuation.
- Access Tailgate Interior: Remove the inner trim panel of the tailgate to expose the latch assembly and wiring harness. Keep fasteners and clips organized.
- Disconnect Electrical Connector: Unplug the multi-pin connector from the lock unit. Inspect connector and wiring for corrosion or damage.
- Remove Mounting Fasteners: Unscrew the bolts retaining the latch assembly and carefully extract the unit from the tailgate.
- Fit New Unit: Install the replacement lock, secure mounting bolts to manufacturer torque settings, reconnect the electrical connector and reassemble the trim.
- Function Check: Reconnect the battery and verify locking/unlocking via key fob, interior switch and manual release. Check tailgate alignment and sealing.
Installation Recommendations
- Use correct tools and follow vehicle manufacturer procedures for trim removal to avoid damaging plastic clips.
- Inspect and clean the connector pins; apply dielectric grease to inhibit future corrosion if appropriate.
- Check tailgate striker and hinges for wear or misalignment—these can affect latch performance and should be corrected during replacement.
- Test full locking cycle several times after installation to confirm reliable operation.
Common Failure Reasons
- Water Ingress And Corrosion: Moisture entering the latch mechanism or connector can corrode electrical contacts and mechanical components.
- Wear Of Internal Components: Plastic gears, pawls or actuator motors may wear out over time, especially on high-mileage vehicles.
- Mechanical Misalignment: Damaged hinges or striker misalignment can prevent the latch from engaging correctly, causing repeated failures.
- Electrical Issues: Damaged wiring, connector corrosion or intermittent supply faults from central locking circuits can simulate a defective latch.

Notes For Technicians
This part is a direct-fit locking assembly intended for vehicle models listed above. Because tailgate locking problems can originate from mechanical alignment or vehicle wiring, perform a visual inspection of the striker, hinges and wiring harness before replacing the latch. Replacing the latch typically resolves failures caused by worn actuators or seized mechanisms.
