Description
Electric central locking lock for the left front door for Peugeot 307 vehicles. Driver’s door.
This used replacement lock is designed for the left front (driver’s) door of the Peugeot 307 and is commonly sought under the part number 9135Z0. Ideal for professional garages and DIY mechanics who need a direct mechanical and electrical fit to restore reliable central locking function.
Technical Information
- Manufacturer: Peugeot (Stellantis)
- Model: Peugeot 307 (Left Front Door / Driver’s Door) – compatible with 307 II applications where the 9135Z0 code is used
- Product Codes: 9135Z0, 9135.Z0
- Other Numbers: NFP (as marked in some listings)
Function
The unit operates the central locking mechanism of the left front door: it receives lock/unlock signals from the vehicle’s central locking system (remote or door switch) and drives the mechanical latch and linkage to lock or unlock the door. Proper operation is essential for door security, vehicle central locking synchronisation and child-lock/door-ajar signalling.
How To Replace
Replacement requires basic door disassembly and electrical caution. Typical replacement steps:
- Disconnect the negative terminal of the battery before starting work.
- Remove inner door trim and vapor/moisture barrier to access the lock mechanism.
- Disconnect the electrical connector and unclip/unscrew the lock unit from the door shell.
- Carefully detach the mechanical linkages (door handle rods and latch cables) and note their positions for reassembly.
- Install the new lock, reconnect linkages and electrical connector, then test lock/unlock function before reassembling the door panel.
- Use dielectric grease on connectors to reduce future corrosion and ensure smooth linkage movement without binding.
Installation Recommendation
- Always disconnect the battery before removal and follow manufacturer procedures to avoid short circuits or damage.
- Check and, if necessary, lubricate linkages and striker alignment when fitting the new lock to ensure smooth operation and avoid premature wear.
- Test the central locking operation (remote and switch) with the door panel temporarily refitted to confirm correct function before final assembly.
- Professional installation is recommended for technicians unfamiliar with door trim removal or linkage adjustment.
Common Causes Of Failure
- Wear Of Internal Plastic Gears Or Motor Brushes: Repeated use and aging can cause internal gear stripping or motor wear, leading to intermittent or no movement.
- Water Ingress And Corrosion: Moisture entering the door can corrode contacts and mechanical components, reducing lifetime.
- Broken Or Detached Linkages: Mechanical connectors between the lock and handles can fatigue or detach, preventing actuation.
- Electrical Connector Or Wiring Faults: Corroded plugs, damaged wires or poor grounding result in loss of signal to the actuator.
Notes For Buyers
Many mechanics search by the OEM part number 9135Z0 or variant 9135.Z0 — including the code in your search will increase the chance of a direct match. This unit is a practical, cost-effective repair option when the door latch assembly or actuator fails. Ensure linkage condition and door striker alignment are checked during replacement to prevent repeat faults.
Suitability
Intended for Peugeot 307 left front door applications (Driver’s door). Verify part number 9135Z0 when matching to the vehicle’s existing lock to ensure compatibility.
