Description
Electric central locking lock for the left rear door for PEUGEOT 307 vehicles. Rear Door On The Driver’s Side.
Product Overview
This electric central locking lock/actuator is designed for the left rear door of the Peugeot 307. It performs the dual function of mechanically latching the door and electrically activating the central locking system, allowing remote and central locking operation. Often searched by product code 9137A0, this part is aimed at professional auto technicians and experienced DIYers who perform body and door repairs.
Function And Benefits
The unit secures the door in the closed position and receives electrical impulses from the central locking system to lock or unlock the door. A properly functioning lock ensures passenger safety, prevents water and wind noise ingress, and keeps the central locking system operating reliably. Replacing a worn or faulty lock restores smooth operation of the locking mechanism and prevents intermittent locking faults.
How The Part Is Replaced
Replacement requires basic door trim removal and some attention to mechanical linkages and electrical connectors. Typical steps:
- Disconnect the battery before starting work.
- Remove the inner door trim and protective vapor barrier to access the lock assembly.
- Disconnect the electrical connector and detach locking rods/linkages from the lock mechanism.
- Remove the mounting screws/bolts and withdraw the old lock assembly from the door.
- Fit the replacement lock, reconnect linkages and electrical connector, then secure with the original fasteners.
- Reinstall the vapor barrier and door trim, reconnect the battery and test locking/unlocking, including remote and interior switch operation.

Installation Recommendations
- Always disconnect the battery prior to removal/installation to avoid short circuits and to protect vehicle electronics.
- Handle the door vapor barrier carefully to avoid tearing; ensure a watertight seal after reassembly to prevent moisture ingress to the lock.
- Check and lubricate moving parts of the latch with suitable grease to ensure smooth operation and to prolong life.
- Verify correct routing and secure fastening of linkage rods so there is no binding or excess play.
- After installation, test central locking operation from all control points (remote, driver’s door switch, passenger switches) and verify that the door closes and latches properly.
Why This Part Fails Most Often
- Corrosion and Water Ingress: Moisture entering the door can corrode metal components or damage the small actuator motor.
- Mechanical Wear: Repeated use causes wear of plastic or metal latch components and springs, leading to poor latching or intermittent operation.
- Broken Linkage Or Clips: Rods and plastic clips that connect the lock to the interior/exterior handles can break or come loose.
- Electrical Connector Issues: Oxidation or poor contact at the connector can cause intermittent electrical operation.
- Impact Damage: Door damage from accidents or slamming can deform the latch or misalign components.
