Electric tailgate lock for Citroen and Peugeot vehicles
High-quality electric tailgate lock designed for Citroën and Peugeot models. This direct-fit replacement part (reference 9684648380) restores reliable locking and remote opening of the rear hatch, making it ideal for professional workshops and do-it-yourself mechanics. The unit controls the latch mechanism and communicates with the central locking system to release or secure the tailgate when operated from the key fob, interior switch or boot release. Common search term: 9684648380.
How It Works
The electric tailgate lock contains a mechanical latch and an electric actuator. When the central locking or tailgate release is activated, an electrical pulse moves the actuator which releases the latch, allowing the tailgate to open. The lock also holds the striker securely when closed to ensure proper sealing and noise reduction.

Installation Recommendations
- Disconnect the battery before starting any work on the electrical system to avoid short circuits and to protect control modules.
- Remove inner tailgate trim to access the lock assembly. Keep fasteners and clips ordered for reassembly.
- Unplug the electrical connector and remove mounting bolts holding the lock. Compare the new unit with the old one to confirm identical mounting points and connector type.
- Before final reassembly, briefly reconnect the battery and test the lock operation (remote, interior switch and manual release) to ensure correct function.
- After testing, fully secure the lock, reconnect connectors, reinstall trim and verify tailgate alignment and striker engagement.
- Use suitable corrosion protection on exposed fixings and ensure drain channels in the tailgate are clear to reduce future moisture ingress.
Most Common Failure Causes
- Water Ingress And Corrosion: Moisture entering the lock mechanism or connector can corrode contacts and mechanical parts.
- Mechanical Wear: Repeated cycles can wear latch components or the actuator, causing sticking or failure to latch.
- Electrical Faults: Damaged wiring, corroded connectors or blown fuses interrupt power to the actuator.
- Damage From Impact: Misaligned tailgate or impacts can deform the latch, preventing proper engagement.
- Debris And Lack Of Lubrication: Dirt or dried grease in the latch prevents smooth operation.
Practical Tips For Reliability
- Inspect and clean the striker and latch area during routine service; apply a light, appropriate lubricant to moving parts.
- Check and secure wiring harnesses to avoid chafing and moisture traps.
- If intermittent operation occurs, test for continuity and voltage at the connector before replacing the entire unit.
