Second Hand Peugeot 408 Central Locking Motor

The Peugeot 408 does use central locking, but the system is typically actuator-based rather than relying on a single central locking motor in the way older systems did — individual door lock actuators (sometimes called motors) are fitted to each door rather than one central unit driving the whole system. If you are searching for a central locking motor, you are most likely actually looking for a door lock actuator for a specific door (nearside front, offside rear, etc.). Let a breaker know which door is faulty and they will be able to source the correct actuator for your registration.

On the Peugeot 408, the part that does the physical locking and unlocking on each door is a door lock actuator — this is the component that fails and causes a door not to lock or unlock with the central locking system. The term 'central locking motor' is sometimes used loosely by customers to describe these individual actuators, but there is no single motor unit that controls all doors centrally on this car. When contacting a breaker, ask specifically for the door lock actuator and state which door position you need.

The Peugeot 408 has been sold in distinct generations — the original 408 was produced from around 2010 onwards, while a new-generation 408 launched in 2023 as a completely different platform. These two generations share no meaningful mechanical relationship, so actuators from one will not be compatible with the other. Always give the breaker your full registration so they can confirm the correct actuator for your exact vehicle.

Trim level — for example Active, Allure, or GT — does not affect the door lock actuator fitted to your Peugeot 408; the actuator is determined by the door position and the generation of the car, not the specification level. You may find minor cosmetic differences in the surrounding door furniture between trims, but the actuator mechanism itself should be the same across the range for a given generation. Confirm with the breaker using your registration to be certain.

Actuators can sometimes differ between front and rear door positions even on the same vehicle, so it is not safe to assume any door actuator from a donor car will fit your nearside rear door without checking. Give the breaker your registration and specify that you need the nearside rear door lock actuator, so they can pull the correct unit from a matching donor vehicle. This will avoid the risk of receiving a part that physically fits the door but has the wrong mechanism for that position.
