Description
Lock cable for the central locking of left and right front doors for PEUGEOT 307 vehicles.
This genuine-style door lock cable (often searched under code 9151Y1 or 9151.Y1) is designed for the front left and right doors of the Peugeot 307. Ideal for professional workshops and competent DIY mechanics, the cable restores reliable mechanical linkage between the interior/exterior door handles and the central locking mechanism. The part is optimized to match factory routing and connector styles used on Peugeot 307 models, helping to eliminate common symptoms such as doors that fail to lock or open from the handle.
Function: The cable transmits motion from the door handle or lock actuator to the latch, converting lever movement into the linear travel needed to operate the central locking latch. A correctly fitted cable ensures smooth operation of manual and central locking, prevents intermittent unlocking/locking issues, and maintains proper door-security behavior.
How To Replace
Basic removal and installation steps for a front door lock cable on a Peugeot 307 (general guidance for experienced technicians):
- Remove the interior door trim panel and any vapor barrier carefully to expose the door internals.
- Disconnect the interior and exterior handle linkages from the cable ends—these are usually secured with plastic clips or small retaining pins.
- Unclip the cable from its routing clips along the inner door shell and detach from the latch assembly.
- Install the new cable by following the original routing, securing it into all retaining clips and attaching both ends to the handle and latch. Ensure plastic connectors are fully seated.
- Before reassembling the door panel, test the locking/unlocking operation several times to confirm smooth travel and correct latch engagement.
- Reinstall the vapor barrier and interior trim, verifying that no wiring or mechanisms are pinched and that the handle operation is unhindered.
Why This Part Fails Most Often
Failure Causes: The most common causes of cable failure are wear of the inner cable or outer sheath, breakage of plastic end connectors, corrosion from moisture ingress, deformation from impacts or door misalignment, and long-term fatigue from frequent use. Cold climates and salted roads accelerate corrosion and can stiffen or seize cable components.
Typical Symptoms: Difficulty opening or locking the front door from the handle, loose or sloppy handle movement, doors that only lock/unlock intermittently, or the need to operate the lock manually from the latch. Visual inspection often reveals broken plastic connectors or a frayed inner cable.

Installation Recommendations
- Use trim tools to avoid damaging clips and door panels. Keep all removed fasteners organized for correct reassembly.
- Lubricate pivot points and the latch with suitable grease to reduce wear and ensure smooth operation after fitting the new cable.
- Check cable routing carefully—incorrect routing or pinched sections will shorten service life and impair function.
- Replace broken plastic clips and retainers; they are inexpensive and prevent premature cable movement or disconnection.
- After installation, perform several full open/close and lock/unlock cycles to confirm correct operation before returning the vehicle to the customer or completing the repair.
