Description
Electric central locking lock for the left front door of the Peugeot 307. There are two visual variants, but they are 100% interchangeable. Driver’s door.
This electric door lock (central locking actuator) for the left front door of the Peugeot 307 is an original-fitment style component used to operate the central locking mechanism on the driver side. It is a direct replacement part commonly searched by part number 9135L0 and is suitable for technicians and experienced DIY mechanics who maintain or repair Peugeot 307 vehicles.
Key Benefits
- Direct fit for Peugeot 307 left front (driver) door — easy swap without body modification.
- Two visual housings exist, but both are fully interchangeable in function and fitment.
- Restores reliable central locking operation: locking/unlocking and door latching.
- Improves vehicle security and convenience compared with a failing or intermittent lock unit.
Function And Application
The unit performs the mechanical locking/unlocking action for the driver’s door as part of the vehicle’s central locking system. It contains an electric actuator coupled to the latch mechanism to move the locking pawl. When fitted correctly it communicates via the vehicle wiring to respond to remote lock/unlock commands and the interior lock switch.
Compatibility
Designed for Peugeot 307 models requiring part number 9135L0. Because two visual versions exist but are 100% interchangeable, focus on matching the part number and connector type rather than the outer appearance. Always verify connector pin layout and mounting points when replacing the unit.
Replacement Procedure (Overview)
- Remove interior door trim and any covers to access the latch assembly and wiring harness.
- Carefully detach the moisture/foil barrier to avoid tearing.
- Disconnect the electrical connector from the lock actuator and unbolt the latch assembly or actuator retaining screws.
- Swap the actuator, refit bolts to the specified torque, reconnect wiring and test operation before reassembling the door trim.
- Check lock/unlock function from remote, interior switch and manual key to ensure correct installation.
Recommendation For Installation
- Work in a dry, well-lit area and use trim tools to avoid damaging panels and clips.
- Before disconnecting any electrical connectors, set the ignition off and isolate any active circuits if possible; for safety, disconnect the negative battery terminal when performing extensive door electrical work.
- Inspect door wiring looms and rubber gaiters for chafing or corrosion while the door is open — a damaged wire is a common cause of intermittent faults.
- After installation, cycle the lock several times and confirm correct latching and child-safety interlocks (if fitted).
Why The Part Commonly Fails
Common failure modes for electric door locks include:
- Wear Of Internal Gears Or Motor — Repeated use over years can wear plastic gears or the small DC motor inside the actuator, causing slow or failed movement.
- Moisture Ingress — Water penetration into the mechanism leads to corrosion, sticking or short circuits in the actuator motor or switches.
- Damaged Wiring Or Connectors — Chafed wires in the door harness or poor connector contact can cause intermittent operation or failure to receive locking signals.
- Mechanical Damage — Impact to the door or latch area can bend linkages or fail the latch mechanism independent of the actuator motor.

Notes For Professional Use
This part is intended for professional installers and experienced DIYers. Because there are two visual variants that are interchangeable, mechanics should verify connector fit and mechanical engagement during installation. Replacing the actuator is a common and cost-effective repair to restore proper central locking function on the driver’s door.
