Description
Mechanical lock for right front door for Citroën Berlingo and Peugeot Partner I and II
Overview
This right front door mechanical lock (part number 9136P7) is designed for use on Citroën Berlingo and Peugeot Partner models from the first and second generations. The unit secures the door by engaging the striker, interfaces with interior and exterior handles and linkage rods, and forms the core mechanical element of the door locking system. Ideal for professional workshops and experienced DIY mechanics searching by model or part code (9136P7).
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën Berlingo I, Citroën Berlingo II, Peugeot Partner I, Peugeot Partner II
- Product Codes: 9136P7
- Additional Numbers: NFP
Function And Typical Use
The lock assembly secures the door by catching the striker on the door frame and transferring forces to the door structure. It transmits mechanical movement from the interior and exterior handles and from central locking rods or cables where fitted. Proper operation is essential for door closing, safety and central locking integration.
Replacement Procedure
- Remove the interior door trim and protective moisture barrier to access the lock mechanism.
- Support the window and disconnect any rods, cables or electrical connectors attached to the lock (if present).
- Unscrew the fixing bolts holding the lock in the door shell and carefully withdraw the mechanism.
- Install the replacement unit, making sure linkage rods and clips are correctly seated and door handles operate freely.
- Test mechanical operation: open/close door, operate interior and exterior handles, and verify central locking function if applicable before reassembling the door trim.
Installation Recommendations
- Perform installation on a stable lift or with the door supported; avoid straining linkage or cables.
- Inspect and, if necessary, renew broken plastic clips, bent rods or corroded fasteners when replacing the lock.
- Apply suitable light grease to moving parts and latch surfaces to ensure smooth engagement and reduce wear.
- Align the lock so the door closes without binding; incorrect alignment can cause premature wear and noisy operation.
- After installation, check operation of central locking and remote locking (if fitted) and confirm that all manual and remote actions fully engage the latch.
Why This Part Commonly Fails
- Wear And Fatigue: Repeated mechanical stress on levers, pawls and cams leads to metal wear or plastic deformation over time.
- Corrosion And Moisture Ingress: Water and salt can corrode metal parts or swell/soften plastics, causing sticking or seizure.
- Broken Clips Or Bent Linkage: Impact, forced operation or previous poor repairs often damage linkage clips or rods, impairing function.
- Dirt And Debris: Accumulated dirt in the latch mechanism increases friction and can prevent correct engagement.
Notes For Professionals And DIY Mechanics
Part number 9136P7 is commonly used in searches for direct-fit locks for Berlingo and Partner models. When replacing, check linkage condition and striker alignment to avoid repeat failures. This mechanical lock is suitable for technicians familiar with door trim removal and linkage reassembly.
