Description
Mechanical Lock For The Left Front Door For Citroën Berlingo And Peugeot Partner I And II
Reliable mechanical left front door lock designed for Citroën Berlingo and Peugeot Partner (generations I and II). This sturdy latch assembly secures the front driver-side door, providing positive engagement with the striker and smooth operation of the locking/unlocking sequence. Commonly searched under the product code 9135P1, the unit is suitable for workshop fitment and DIY repairs where a direct mechanical replacement of the latch is required.
Features And Function
The lock provides the primary mechanical latching and release function for the left front door. It secures the door to the body striker, transmits movement from the interior handle and exterior key/cylinder via rods or cables, and interfaces with the central locking actuator where fitted. The mechanism contains a latch pawl, release lever, springs and mounting points compatible with factory door interiors of the listed models.

Installation And Recommendations
Replacement is straightforward for experienced technicians and competent DIYers. Typical procedure:
- Remove the inner door trim and any moisture/vapour barrier to access the lock mechanism.
- Detach any linkage rods or cables from the lock; note their routing and retaining clips for reassembly.
- Unscrew the lock mounting fasteners and withdraw the old unit from the door shell.
- Fit the new lock, ensuring correct alignment with the striker; secure fasteners and reconnect rods/cables.
- Grease moving contact points lightly with an appropriate lubricant and confirm smooth operation of handle, key cylinder and central locking (if present) before reassembling the door trim.
Recommended Tools: Torx/hex sockets, trim tools, needle-nose pliers for clips and retaining springs. Inspect the striker and door alignment during fitment — excessive gap/misalignment accelerates wear on the new lock.
Why The Part Most Often Fails
Door locks on these models typically fail due to mechanical wear and exposure to contaminants. Common causes include worn or broken plastic clips and levers, seized or corroded internal springs and pawls, ingress of dirt and moisture, or disconnected/warped linkage rods. Repeated heavy use, poor door alignment, or impact to the door can also accelerate failure.
Practical Tips For Workshop And DIY Fitters
- Verify smooth mechanical action before refitting the door card; operate the lock several times with the door open to ensure full travel.
- Replace any brittle or damaged retaining clips and inspect the key cylinder and actuator compatibility when present.
- If the vehicle has central locking, test actuator synchronization after installation and ensure electrical connectors (if any) are clean and secure.
- Use light grease on sliding surfaces and corrosion inhibitor on exposed metal parts to extend service life.
