Technical Information

• Manufacturer: Stellantis
• Model: Peugeot 307
• Product Codes: 9135L0
• Additional Numbers: NFP

Installation Recommendation

Removal and installation are straightforward for an experienced technician. Typical procedure:

• Remove interior door trim panel and any moisture barriers to access the lock assembly.
• Disconnect the electrical connector(s) and any Bowden cables (if fitted) from the lock/latch assembly.
• Unbolt the lock unit from the door frame and remove the old mechanism.
• Install the replacement lock, secure fasteners to original positions and reconnect cables and electrical plug(s).
• Check mechanical alignment of the latch striker and adjust if necessary to ensure smooth closing and positive locking.
• Test central locking function, manual operation and key/remote lock/unlock cycles before reassembling door trim.

Recommended tools: Torx/socket set, trim removal tools, small flat screwdriver, multimeter for electrical checks. Always work carefully to avoid damaging door trim and moisture barriers.

Why This Part Fails Most Frequently

• Mechanical Wear: Plastic gears or internal levers can wear or break after years of use, causing the lock to stop moving or become noisy.
• Water Ingress: Moisture entering the door can corrode contacts or seize moving parts, especially in lower door areas.
• Electrical Faults: Corroded connectors, broken wiring or intermittent actuator motor failures lead to unreliable central locking operation.
• Cable/Linkage Damage: Bowden cables or linkage rods can stretch or disconnect, preventing the latch from actuating correctly.

Practical Tips

• Confirm correct orientation: This unit is for the left front (driver) door. Visual variants are interchangeable but verify mounting points and connector alignment during installation.
• Inspect the door striker and latch alignment if closing issues persist after installing the new lock.
• Clean and protect electrical connectors with dielectric grease to reduce future corrosion-related failures.

Final Notes

This lock is a reliable solution to restore secure and consistent door locking on Peugeot 307 driver doors. Supplied under code 9135L0 and compatible with both visual variants, it is designed for quick fitment in workshop conditions.

Technical Information

• Manufacturer: Stellantis (Peugeot / Citroën)
• Model: Peugeot 307 (Left Front / Driver Door)
• Product Codes: 9135L0
• Other Numbers: NFP (as referenced in supplier listing)

Installation Recommendations

Basic steps for replacement (typical procedure):

• Prepare Tools: Door trim tools, Torx/Phillips screwdrivers, ratchet set and pliers.
• Safety First: Disconnect the negative battery terminal before starting work to avoid short circuits and accidental airbag deployment.
• Remove Interior Door Trim: Carefully unclip the door card and remove fasteners to access the latch mechanism. Protect trim clips with a trim tool to avoid damage.
• Access The Latch: Peel back the moisture barrier to expose the actuator and linkage rods.
• Disconnect Electrical Connector And Linkages: Note the positions of rods and clips before removal or mark them to ensure correct reassembly.
• Unbolt The Lock Module: Remove mounting bolts, replace the unit with the new actuator, then reconnect rods and the electrical connector.
• Reassemble And Test: Refit the moisture barrier and door card, reconnect the battery, then check central locking operation from the remote and inside switch. Verify mechanical locking/unlocking and listen for unusual noises.

Recommended For Installation By: Experienced Auto Technicians Or Competent DIY Mechanics. Use Genuine Fasteners And Ensure Correct Rod Clip Orientation To Avoid Rattles Or Misalignment.

Why This Part Fails Most Often

• Water Ingress And Corrosion: Moisture entering the latch area can corrode contacts or mechanical components.
• Wear Of Internal Gears/Plastics: Repeated use leads to worn or broken plastic gears and levers inside the actuator.
• Electrical Motor Failure Or Intermittent Contacts: Motors and switches inside the actuator can fail electrically, causing intermittent operation.
• Mechanical Damage From Forced Operation: Manual forcing of a jammed door can damage linkage or the latch mechanism.

Practical Notes

Searches For This Part Are Often Performed Using The Part Number 9135L0 — Keep The Part Number To Hand When Ordering. Because there are two externally different housings that are fully compatible, visual differences do not affect interchangeability. After replacement, verify smooth mechanical operation of the door and correct function of central locking from both the remote and interior switch.

Compatibility And Fitment

Designed For Peugeot 307 Left Front (Driver) Door Applications. Always Confirm Fitment By Matching The Product Code (9135L0) And The Mounting Points On The Door. This Unit Replaces Faulty Central Locking Actuators That Produce Noisy Operation, Intermittent Locking, Or Complete Loss Of Lock/Unlock Function.
