Description
Electric central locking actuator for PEUGEOT 307. Left front driver’s door.
Reliable replacement electric door lock actuator designed for the left front (driver) door of the Peugeot 307. Ideal for professional workshops and DIY mechanics who require a direct-fit solution to restore central locking function. The unit corresponds to the commonly used part codes 9135N4 and 9135Z0 and integrates with the vehicle’s central locking mechanism to operate door locking/unlocking via remote control or door switch.
Features
- Direct-fit replacement for original equipment on Peugeot 307.
- Electric motor-driven actuator with mechanical linkage for latch operation.
- Designed to restore reliable central locking function and door latching.
- Durable construction with mounting points matching OE locations for straightforward installation.
Applications
Commonly fitted to Peugeot 307 models produced approximately 2001–2008. Confirm fitment by matching the product code printed on the original unit (9135N4 / 9135Z0).
Replacement Procedure
- Preparation: Park vehicle on level ground, ensure ignition off and accessories off.
- Safety: Disconnect the negative battery terminal before starting work to avoid electrical shorting.
- Access: Remove the door trim panel and any moisture/sound insulation to access the lock assembly.
- Disconnect: Unplug the electrical connector from the actuator and detach any linkage rods or clips connected to the latch.
- Remove: Unscrew the actuator mounting fasteners and remove the faulty unit from the door shell.
- Install: Fit the new actuator, secure fasteners to the specified torque, connect linkage rods and electrical connector, and refit insulation and trim.
- Test: Reconnect the battery, test central locking operation from the remote and interior switches, and check smooth mechanical operation of the latch.

Installation Recommendations
- Use appropriate trim tools to avoid damaging door panels and clips.
- Ensure all linkage rods and clips are correctly seated; improper linkage alignment can prevent full locking or unlocking.
- Check door latch and striker alignment after installation; adjust as necessary to prevent binding.
- Lubricate mechanical linkages and latch pivot points with suitable grease to reduce wear and noise.
- After installation, perform several lock/unlock cycles and test from all controls (remote, interior switch, and manual key) to confirm correct operation.
Why This Part Most Frequently Fails
- Water Ingress: Moisture or water entering the door can corrode internal components or short the motor.
- Plastic Gear Wear: Internal plastic gears and mechanical linkages degrade over time, especially with heavy use.
- Motor Burnout: Repeated operation under strain (misaligned latch or frozen linkages) can overload the actuator motor.
- Mechanical Fatigue: Metal linkage points and clips can deform or break after years of use, causing incomplete engagement.
