Description
Electric central locking lock for the left rear door of the PEUGEOT 407. Door behind the driver.
This electric door lock (central locking actuator) is designed for mechanics and DIY enthusiasts who need a reliable replacement for the left rear door of the Peugeot 407. It restores remote and manual locking functions, improves security and prevents water or dirt from disabling the central locking system. Suitable for direct replacement where the original part numbers match, this unit is a common fit for Stellantis group vehicles under Peugeot/Citroën references.
The lock operates as part of the central locking system, converting electrical signals from the door lock module into mechanical movement that locks and unlocks the door latch. Typical failure symptoms include the door not locking/unlocking with the remote, intermittent operation, loud grinding or clicking noises inside the door, or the door remaining stuck in the locked or unlocked position. Replacing the actuator usually restores full function and eliminates noise caused by worn gears or a failing motor.

Installation Recommendations
- Remove the inner door trim and protective vapor barrier carefully to avoid damaging clips and the moisture membrane.
- Disconnect the electrical connector and unclip the lock rods from the actuator (note rod positions before removal).
- Unbolt the lock actuator from the door latch assembly and replace with the new unit, ensuring correct alignment of the latch and rods.
- Test locking and unlocking electrically before reassembling the door trim to confirm correct function.
- Apply a small amount of appropriate grease to pivot points and reconnect the moisture barrier to protect the mechanism.
- Replace any damaged plastic clips or fasteners to ensure the door panel fits securely and water cannot enter the mechanism area.
Why This Part Fails Most Often
- Plastic Gear Wear Or Breakage: Internal plastic gears can become brittle with age and eventually crack or strip, causing the actuator to lose mechanical drive.
- Motor Or Electrical Failure: The small DC motor inside the actuator can fail after prolonged use or due to heat/corrosion, resulting in no movement or intermittent operation.
- Water Ingress And Corrosion: Moisture entering the door can corrode electrical contacts or seize mechanical parts, especially if the vapor barrier is damaged.
- Rod Or Linkage Detachment: Bent or detached linkage between the actuator and latch can mimic actuator failure and should be inspected during replacement.
- Age And Usage: High-mileage vehicles and cars exposed to harsh environments are more likely to experience actuator wear.
Choose this replacement lock if the part numbers match and you need a straightforward swap to restore central locking on the left rear door of a Peugeot 407. Proper installation and protection from moisture will extend the service life and ensure quiet, reliable operation.
