Purpose and function in the vehicle

The presented door lock is designed for installation in the front right door of the Land Rover Discovery L319. It is responsible for:

• mechanically locking the door panel to the body pillar,
• transferring movement from the external and internal handle to the lock mechanism,
• working with the central locking system and remote control operation,
• maintaining the correct position of the lock tongue relative to the striker in the bodywork. By using an original design, high repeatability of the mechanism's operation is maintained, which reduces the risk of jamming, doors failing to close, or comfort system errors.

Construction and advantages of the original lock actuator

The door lock actuator in the Discovery L319 combines the mechanical and electrical parts in one housing, which allows for efficient control from the comfort module. Using a factory Land Rover solution means:

• appropriately selected electric motor operating force relative to the door weight,
• proper compatibility with factory wiring harnesses and connectors,
• maintaining the original operating characteristics of the central locking system,
• compatibility with factory safety and door locking settings. Compared to random replacements, the original door lock ensures stable operation over a long service life and minimizes the risk of coding issues or communication problems with the vehicle's electronics.

Vehicle placement and installation aspects

The component is designed for installation in the front right door, which is important for both mounting geometry and the direction of the mechanism's operation. When selecting the part, it is crucial to pay attention to:

• compatibility of the installation side (front – right side of the vehicle),
• proper routing of the internal and external handle cables,
• correct connection of the electrical connector to the door wiring. A properly selected door lock allows for installation in a plug-and-play manner, without the need for bodywork modifications or mounting adaptations, which shortens repair time and reduces labor costs.

Condition, selection, and service application

The offered item comes from the Internal locks and latches group and is intended as a service part for problems with closing, locking, or unlocking the door. It is particularly useful in situations where:

• the door does not respond to central locking commands,
• the lock jams mechanically or operates with noticeable resistance,
• there are intermittent problems with opening the door from the inside or outside. Using an original Land Rover solution allows you to maintain consistency of the locking system with the other doors and reduces the risk of improper interaction with the vehicle's electronics after replacement. If you are planning a comprehensive repair or upgrade of the door lock zone in your Land Rover and need other elements from the same group, such as actuators, latches, or handle mechanisms, check the available parts in the Land Rover Internal locks and latches category.

Technical support and knowledge about OEM parts

When selecting used OEM elements for the drivetrain or locking system, it is worth relying on proven sources and reliable verification of the part's origin.
