Description
Electric central locking lock for the left front driver’s door for PEUGEOT 307 Driver’s door.
Direct-fit replacement lock for the left front (driver’s) door of the Peugeot 307. Supplied to restore reliable central locking and door latching after failure of the original unit. Ideal for professional workshops and experienced DIYers who search by product code (e.g. 9135Z0). The unit operates on the vehicle’s 12V electrical system and integrates with the central locking mechanism to lock/unlock and secure the door. Replacing the lock typically returns smooth mechanical operation and restores remote or central locking functions when the original actuator or latch has worn, seized or been damaged.
Technical Information
- Manufacturer: Peugeot / Stellantis
- Model: Peugeot 307 (Left Front / Driver’s Door)
- Product Codes: 9135Z0, 9135.Z0
- Other Numbers: NFP (as listed)
Installation Recommendations
- Always disconnect the vehicle battery before starting work to avoid short circuits and unintended airbag deployment.
- Remove the inner door trim panel and any moisture barriers carefully to access the lock mechanism.
- Disconnect electrical connector(s) and detach mechanical linkages (rods and clips). Note the orientation and routing of linkages for correct reassembly.
- Unscrew the lock assembly mounting bolts, remove the old unit and fit the replacement. Transfer any required linkages or striker parts if applicable.
- Reconnect the electrical connector, briefly reconnect the battery and test locking/unlocking (remote and manual) before reassembling the door trim.
- Lubricate moving latch parts with an appropriate long‑lasting grease and ensure smooth rod/clip operation. Refit seals and trim panels securely.
Why The Part Commonly Fails
- Mechanical Wear: Plastic gears and latch components wear over time, causing sticking or complete failure.
- Water Ingress and Corrosion: Moisture entering the door can corrode connectors and components or cause the actuator to seize.
- Electrical Faults: Poor contacts, broken wires or a failed actuator motor result in intermittent or no locking action.
- Impact Or Misalignment: Door impacts or misaligned striker/latch can overload and damage the lock mechanism.
- Aging And Dirt: Accumulated dirt, rust or lack of lubrication increases friction and accelerates failure.
This lock is a practical spare for technicians and competent DIYers restoring central locking on Peugeot 307 vehicles. Searching by the product code (9135Z0) will often lead directly to the correct replacement part.
