Purpose and function of the rear left door lock

The presented lock is dedicated to the rear, left side of the body, making it structurally compatible with the door geometry and bodywork guides. It is responsible for:

• mechanical locking of the door leaf in the body pillar,
• stable retention of the door in the closed position while driving,
• proper interaction with the external and internal door handles,
• transferring movement from the rods or central locking mechanism.

Thanks to a design consistent with Peugeot factory solutions, the lock maintains the correct operating geometry, which reduces the risk of improper closing, play, or excessive hinge wear.

Construction and fitment to the door system

The rear left door lock belongs to a group of components responsible for passive safety and user comfort. Its construction includes a precise locking mechanism that interacts with:

• the striker tongue in the body pillar,
• rods or control cables from the handles,
• the central locking control system (if present in the vehicle).

The placement in the rear, left part of the vehicle allows for direct installation in the door without the need for modifications, which is particularly important when replacing the component after a collision or mechanism failure.

Benefits of using an original Peugeot lock

Using a lock from the same design line as the vehicle's factory equipment brings a number of practical benefits:

• High installation compatibility – mounting holes, rod attachment points, and housing shape are matched to the model's door, which facilitates installation.
• Stable mechanism operation – proper locking reduces rattling, play, and unwanted noises while driving.
• Safe door closing – a properly functioning lock reduces the risk of accidental opening while driving.

This solution is particularly recommended for post-accident repairs, replacing a worn-out mechanism, or restoring full functionality of the locking system in the rear door.

Installation area and service recommendations

Placement in the rear, left part of the vehicle requires removing the door trim and accessing the interior of the door shell. During installation, it is worth paying attention to:

• correct routing of control rods and cables,
• precise seating of the lock in the factory mounting points,
• checking the interaction with the handles and the child safety lock,
• verifying proper door closing along the entire perimeter of the seal.

After installation, it is recommended to check the mechanism's operation several times by opening and closing it from both the outside and the inside to ensure that the lock functions smoothly and without jamming.

If you are planning a comprehensive repair or upgrade of the door lock area in your Peugeot and need other components from the same group, such as locking mechanisms, strikers, or cylinders, check the available parts in the Peugeot locks and latches category.
