Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C5 I, Citroën C5 II
- Product Codes: 9136J9
- Additional Numbers: NFP
Installation Recommendations
- Safety First: Disconnect the negative battery terminal before starting work to avoid short circuits and inadvertent operation of the central locking system.
- Door Trim Removal: Remove interior door handle trim, screws and plastic clips, then carefully lift off the door card to access the lock assembly.
- Accessing the Lock: Fold back the moisture barrier to reach the latch and actuator. Take care not to tear the vapor barrier.
- Disconnect Electricals and Linkages: Unplug the electrical connector and unclip the locking rods. Mark or photograph linkage positions for correct reassembly.
- Remove and Replace: Unscrew the latch mounting bolts, remove the old unit and install the replacement. Ensure the new lock sits correctly and bolts are tightened securely without over-torquing.
- Reconnect and Test: Reconnect rods and electrical connector, then test central locking, remote locking and manual operation before refitting the door card.
- Final Steps: Refit the moisture barrier and interior trim. Apply light lubricant to the latch mechanism if needed to ensure smooth operation.
Why This Part Most Often Fails
- Wear Of Internal Components: Plastic gears and small electric motors inside the actuator wear out over time, causing the unit to stop moving correctly.
- Water Ingress And Corrosion: Moisture entering the door can corrode electrical contacts or seize mechanical parts, especially in older cars or vehicles exposed to wet environments.
- Broken Linkages Or Clips: External rods and plastic clips connecting the lock to the handle and latch can break, leading to loss of function even if the actuator itself spins.
- Electrical Connector Problems: Corroded or loose connectors cause intermittent operation or complete failure of the central locking signal to reach the actuator.
- Mechanical Damage: Impact from forced entry or door damage can deform the latch mechanism and prevent normal locking/unlocking.
Typical Symptoms: Door Won’t Lock Or Unlock With Remote, Intermittent Locking, Unusual Grinding Or Clicking Noises From The Door, Or The Door Becoming Difficult To Open/Close.
Replacement Tip For Technicians: Always compare the part code (9136J9) and connector type with the old unit before installation. Test electrical operation and mechanical travel with the door open to ensure correct function. Lubricate moving parts and check surrounding components (handles, rods, door striker) to avoid recurring problems.
