Purpose and placement in the vehicle

The presented lock is designed to operate in the rear left door area, where it is responsible for mechanical locking and interaction with the rods and handle. Its placement in the rear part of the body requires precise fitting with the door sheet metal, guides, and seals; therefore, using a lock dedicated to a specific Peugeot model minimizes the risk of closing problems or play on the catch.

Construction and technical function

The door lock from this construction group combines several key functions:

• mechanical locking of the door panel against the body pillar,
• transferring movement from the external and internal handle to the latch mechanism,
• interaction with rods or control cables inside the door,
• stable maintenance of the door in the closed position while driving.

The appropriate geometry of the working elements translates into smooth opening and closing and reduces noise resulting from improper closing. Using the original Peugeot design allows for maintaining the factory operating parameters of the mechanism.

Benefits of using an original Peugeot lock

Choosing a lock dedicated to a specific Peugeot model brings a number of practical advantages, important for both the user and the workshop installing the component:

• Factory fit – the lock is designed for specific door geometry, which facilitates installation and reduces the need for modifications.
• Consistency with other door elements – proper cooperation with handles, rods, and other components from the Locks and latches group.
• Stable operation in daily use – proper locking reduces the risk of accidental door opening while driving.
• Easier diagnostics – a mechanism consistent with factory solutions facilitates service and potential adjustment.

Component condition and installation aspects

The offered door lock is in Used condition, which means it comes from disassembly and was previously used in a vehicle. This type of part is a good solution in situations where you want to maintain the original design while optimizing repair costs. Before installation, it is recommended to perform a standard check of the mechanism, verify the smoothness of the latches, and ensure correct alignment with the catch on the pillar.

During installation, it is worth paying attention to:

• correct routing of control rods or cables,
• precise alignment of the lock relative to the door edge,
• checking the closing and locking after initially tightening the mounting bolts.

Expansion of the Peugeot locking system

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