Description
Electric central locking door lock – right front door for PEUGEOT 307 Passenger side front
This Electric Central Locking Door Lock is a direct-swap replacement for the right front (passenger side) door of the Peugeot 307. Supplied to match OEM references 9136P1 and 9136AA, the unit integrates the latch mechanism and central locking actuator to restore secure locking, reliable door catching and remote locking function. Built for workshop use and DIY repairs, this lock is suitable for mechanics who need a dependable replacement part that fits the original mounting and connector layout.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Peugeot 307
- Product Codes: 9136P1, 9136AA
- Additional Numbers: 9136AA | 9136P1
Fitment And Applications
Primary fitment: Peugeot 307 (passenger side, right front). This part is commonly used across typical 307 body variants produced in the first generation, including hatchback and estate versions depending on production variant. The unit replaces the factory door lock assembly on the right front door and mates to the original actuator connector and mechanical linkages.
Function
The assembly combines the latch, locking mechanism and electric actuator that operate the central locking function for the right front door. When activated by the remote fob or central locking switch, the actuator moves the latch into the locked or unlocked position. The latch also provides the mechanical catch that keeps the door closed and aligns the striker on the door frame.
Replacement And Installation
- Disconnect the negative battery terminal before starting work to prevent electrical shorting and inadvertent airbag/seatbelt system activation.
- Remove the interior door trim panel carefully to access the lock assembly—this typically requires removing screws, clips and the window control bezel.
- Peel back the water/moisture barrier to expose the lock mechanism and wiring connector.
- Disconnect the electrical connector and any door cable/linkage from the latch. Note the routing and orientation of rods and clips for correct reassembly.
- Unbolt the lock assembly from the door shell, remove the old unit and install the replacement in reverse order; ensure all bolts and clips are torqued to manufacturer guidance and linkages are correctly seated.
- Test locking/unlocking operation (central locking and manual lock) before refitting the trim panel. Lubricate the latch with appropriate lock grease for smoother operation.
Installation Recommendations
- Use correct trim tools to avoid damaging plastic retainers and door cards.
- Inspect door rods and plastic clips for wear and replace any brittle or broken components to prevent future malfunctions.
- Apply light lithium or silicone-based grease to moving parts of the latch to reduce wear and noise.
- After installation, confirm full function of central locking from both remote and interior switches and verify door alignment and closing force.
Why This Part Most Commonly Fails
Door lock assemblies on the Peugeot 307 typically fail due to a combination of mechanical wear and environmental factors. Common causes include:
- Water ingress and corrosion that degrade electrical connectors, actuator motor windings or internal metal parts.
- Worn or broken plastic gears or internal actuator components caused by long-term use and repeated cycles.
- Damaged or stretched linkages and clips that prevent the actuator from fully transferring motion to the latch.
- Impact damage from door slams or accidents that deform the latch or striker alignment.
For professional mechanics and competent DIYers, replacing the door lock with the correct OEM-referenced unit (9136P1 / 9136AA) restores reliable central locking and door security while avoiding intermittent electrical faults and noisy or unreliable operation.
