Purpose and function in the vehicle

The presented lock is dedicated to the Land Rover Discovery 3 L319 model and operates in the area of the rear right door. It is responsible for the mechanical and internal part of the locking system, working in conjunction with the external handle and the internal opening mechanism. A correctly selected component in this location is crucial for passenger safety and the sealing of the vehicle body.

The placement on the vehicle, defined as rear – right side, allows for precise fitting to the door structure, guides, and linkages. As a result, the lock works with factory mounts, which facilitates installation and reduces the risk of improper fitment.

Benefits of using an original lock

Using an original door lock latch in the Land Rover Discovery 3 L319 allows you to maintain the factory operating parameters of the door mechanism. The main advantages include:

• maintaining the correct geometry of the handle and linkage operation,
• proper locking and unlocking using the handle and central locking system,
• consistency with factory body tolerances, which reduces rattles and play,
• the ability to install directly in place of a worn or damaged component.

Consequently, replacing a worn mechanism with an original lock from the Locks and Latches group restores the comfort of door usage and improves the vehicle's daily functionality.

Installation characteristics

The placement defined as the rear right door means that the lock design is matched to a specific body panel. The mounting holes, attachment points, and routing of the linkages are consistent with the factory Land Rover design, which promotes efficient installation by a mechanic or an experienced user.

The item comes from professional dismantling, which in practice means it was removed from a complete vehicle, rather than from randomly selected components. This type of solution is often chosen as a reasonable compromise between cost and maintaining original structural quality.

Condition and service application

The product is offered as a used original Land Rover component, which allows for an economical repair of the door locking system while maintaining compliance with the factory design. This type of lock is suitable both for standard replacement of a worn mechanism and for post-accident repairs where restoring full door functionality is necessary.

In service practice, the rear right door lock latch is often replaced in situations such as: problems with opening or closing the door, lack of response to the central locking system, or mechanical damage following a collision or tampering with the lock. Replacing it with an original component reduces the risk of recurring faults resulting from the poor fit of aftermarket parts.

Repair expansion and selection of related components

If you are planning a comprehensive repair or upgrade of the cabin access zone in your Land Rover and need other elements from the same group, such as locking mechanisms, cylinders, or actuators, check the available parts in the Land Rover Locks and Latches category.

When planning broader service work, it is also worth considering the selection of other components from professional dismantling.
