Description
Electric central locking actuator – driver’s door. For Peugeot 307 3-door vehicles.
High-quality replacement electric lock for the driver’s door of the Peugeot 307 three-door. Designed for professional workshops and DIY mechanics who need a reliable central locking actuator that restores proper locking, unlocking and remote central locking function. This unit directly actuates the door lock mechanism and integrates with the vehicle’s central locking system to provide smooth operation and secure door closure.
Key Features and Benefits
Reliable mechanical actuation of the door lock for consistent locking and unlocking. Direct fit for compatible Peugeot 307 3-door models, which simplifies installation and reduces bench time. Restores remote central locking response and eliminates intermittent failures caused by worn internal components. Suitable for professional repair shops and competent DIY enthusiasts seeking an OEM-fit replacement.
How It Works
The actuator converts electrical signals from the central locking system into mechanical movement that operates the door latch. It contains a small electric motor and gearing that push or pull the lock rod/cable to lock or unlock the door when triggered by a remote, door switch or comfort module.
Typical Symptoms Indicating Failure
- Door does not lock or unlock with the remote or central locking switch.
- Intermittent operation or noisy grinding from inside the door when locking/unlocking.
- Manual key operation becomes stiff or unreliable in the affected door.
- Lock works inconsistently, often after exposure to moisture or long-term use.
Why This Part Fails Most Often
Common causes of failure include water ingress and corrosion, wear of internal plastic gears or motor brushes, and mechanical fatigue of linkage or mounting points. Accumulated dirt and lack of lubrication can accelerate wear. Electrical issues such as wiring corrosion or connector problems may mimic actuator failure but often coincide with mechanical wear in older vehicles.
Replacement Procedure (Overview)
Suitable for experienced mechanics and competent DIYers. Basic steps:
- Disconnect the negative battery terminal before beginning work.
- Remove the interior door trim carefully using trim tools to avoid breaking clips.
- Peel back the moisture barrier as required and locate the actuator assembly.
- Disconnect the electrical connector and any linkage or rods attached to the actuator.
- Remove the mounting screws/bolts securing the actuator and extract the unit.
- Install the new actuator, reattach linkage and connector, and test locking/unlocking before reassembling the door trim.
- Reinstall the moisture barrier and interior trim, reconnect the battery, and perform a final function check.
Use appropriate hand tools (screwdrivers, Torx) and a trim removal tool. Avoid forcing plastic clips and ensure connectors are fully seated. Lubricate moving latch points with a suitable grease to extend service life.

Recommended Installation
Perform installation in a dry, well-lit workspace. Always disconnect the battery before removing the door trim to avoid short circuits. Inspect the door moisture barrier and water drains; repair any leaks to prevent premature failure of the replaced actuator. Check the condition of linkage rods and clips and replace if bent or worn. Test the new unit several times (remote and manual) before final reassembly.
Suitable For
Peugeot 307 three-door vehicles requiring replacement of the driver’s door central locking actuator. Ideal for technicians and DIY mechanics who prefer a direct-fit replacement part referenced by part number 9135K4.
Buying this actuator helps restore reliable central locking performance and prolongs the service life of the door locking mechanism when installed and maintained correctly.
