How It Works
The electric door lock assembly houses the latch mechanism and the electric actuator that operates the central locking. When triggered by the remote or the vehicle’s central locking system, the actuator moves internal linkages to lock or release the latch. Proper engagement of the latch secures the door to the striker on the body and allows smooth opening when released.

Replacement / Installation Overview
General replacement steps (recommended for experienced technicians and competent DIYers):
- Disconnect the negative battery terminal before starting work to avoid short circuits and protect vehicle electronics.
- Remove the interior door trim panel and any moisture barrier to access the lock assembly.
- Disconnect electrical connector(s) and unclip or detach the lock control rods/cables from the latch mechanism.
- Remove the fixing bolts securing the lock to the door shell and withdraw the old unit.
- Install the new lock in reverse order: secure with bolts, reconnect rods/cables and electrical connector, reseal moisture barrier and refit the door trim.
- Test locking/unlocking, handle operation and central-locking integration before finishing the job.
Installation Recommendations
- Always disconnect the battery before disconnecting door electrical connectors.
- Keep fasteners and clips organised during disassembly to ensure correct reassembly.
- Inspect and, if necessary, lubricate the striker and moving parts with a suitable dry or light grease to prevent binding.
- Check door alignment and striker condition—misalignment can cause premature wear of the new lock.
- After installation, cycle the locks several times and confirm correct operation from the remote, interior switch and key.
Why These Locks Fail
Common failure causes include:
- Water ingress and corrosion that damage the latch or electrical actuator.
- Wear of plastic gears or mechanical linkages inside the actuator from repetitive use over many years.
- Mechanical damage from slamming doors or misaligned striker plates that stress the latch.
- Electrical faults such as corroded connectors, broken wiring, or a failed actuator motor.
Why Choose This Part
If the passenger door on your Peugeot 407 fails to lock, unlock, or latch securely, replacing the electric lock assembly with the correct part number is the most effective repair. Using the OE reference numbers included helps ensure you receive a compatible unit and reduces downtime in professional environments.
