Description
Electric central locking actuator – right front door for PEUGEOT 307. Front passenger side.
Replacement electric door lock/central locking actuator for the right front (passenger) door of the Peugeot 307. The unit operates the door latch as part of the vehicle’s central locking system, enabling remote and interior locking/unlocking. Commonly searched for under part numbers 9136P1 and 9136AA.
This actuator ensures reliable engagement and release of the door latch, restoring proper locking function and preventing doors from remaining unlocked or stuck. It is intended for professional fitment by mechanics as well as experienced DIY enthusiasts who are familiar with door trim removal and vehicle electrical systems.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Peugeot 307
- Product Codes: 9136P1, 9136AA
- Additional Numbers: None Specified
Function
The actuator converts the electrical locking signal into mechanical movement to operate the door latch. It works together with the vehicle’s central locking control unit and door latch mechanism to lock and unlock the door via remote control, key, or interior switch.
Compatible Models
Fitment for Peugeot 307 right front passenger door. Confirm fitment by comparing part numbers 9136P1 or 9136AA with the existing unit before installation.
Replacement Procedure
- Disconnect the negative battery terminal to avoid short circuits.
- Remove the inner door trim panel carefully to access the lock assembly (remove screws, clips and any vapor barrier as required).
- Disconnect the electrical connector from the actuator and detach any linkage rods from the latch mechanism (note rod positions for reassembly).
- Unscrew and remove the old lock/actuator from the door shell.
- Install the new actuator, refit linkage rods and electrical connector, and secure fasteners to original positions.
- Reconnect the battery and test locking/unlocking operation before refitting the door card. Verify remote, interior switch and manual operation.
- Reassemble the door trim and test again to ensure proper alignment and function.
Installation Recommendations
- Apply a small amount of silicone or white lithium grease to linkages and latch pivot points to reduce wear and noise.
- Use dielectric grease on electrical connectors to improve corrosion resistance and contact reliability.
- Check door seals and drainage channels for blockages to reduce future water ingress.
- Test actuator operation fully before completing door reassembly to avoid repeated disassembly.
Common Failure Causes
Actuators typically fail due to a combination of mechanical wear and environmental exposure. Frequent causes include water ingress leading to corrosion, degraded plastic gears, seized motor bearings, broken internal linkages and corroded connectors. Repeated heavy use and damaged door seals accelerate wear.
Why The Part Most Commonly Fails
The most frequent reason for failure is moisture ingress into the actuator mechanism, which causes corrosion and accelerated wear of plastic gears and electrical contacts. Over time this leads to loss of motor torque or mechanical jamming, resulting in intermittent or complete failure of the door lock function.
Notes For Buyers
This part is often searched by the product codes 9136P1 and 9136AA. Ensure the part numbers match the unit being replaced and follow safe working practices when removing interior trim and working with vehicle electrics.
