Purpose and function in the vehicle

The presented door lock is designed for installation in the rear left body section of Land Rover L319 series vehicles. The component is responsible for:

• mechanical locking and unlocking of the door leaf,
• cooperation with the external handle mount,
• integration with the central locking system controlled by a 434 MHz radio signal.

By combining the lock and handle mount functions into a single module, consistent operation of the entire door mechanism is achieved, reducing the risk of play, improper closing, and synchronization issues between the actuator and the handle.

Construction and integration with the 434 MHz system

The lock module has been designed as a component compatible with the factory 434 MHz remote control system. This means that:

• the component is prepared for operation within the original Land Rover L319 electrical architecture,
• signals from the key fob and comfort module are correctly interpreted by the locking mechanism,
• the response time to open and close commands remains predictable and repeatable.

Such alignment helps maintain factory safety parameters and user comfort without the need for additional adapters or wiring modifications.

Benefits of using an original Land Rover lock

Choosing an original door lock with handle mount for the Land Rover L319 offers a number of practical advantages:

• Factory fit – mounting geometry and mechanism kinematics are consistent with the door construction, which facilitates installation and ensures proper door leaf fitment.
• Consistency with vehicle electronics – the lock works with the existing central locking and radio control system, minimizing the risk of communication errors.
• Stable operation in the rear left body zone – the component is dedicated to a specific vehicle location, which reduces wear resulting from improper installation.

The item comes from the used original parts segment, which allows for combining controlled service costs with the preservation of the construction intended by the vehicle manufacturer.

Condition, verification, and service application

The product is offered as a used part, which in practice means that it has already been in service in a vehicle but is still suitable for further use after proper installation. Such components are often chosen in situations where:

• a quick replacement of a damaged door lock is necessary without interfering with the electrical installation,
• maintaining the original vehicle specification is a priority,
• optimizing repair costs while maintaining compatibility with the 434 MHz system is important.

Before installation, it is recommended to perform a standard check of the mechanism's operation and verify its functionality in conjunction with the vehicle's installation, in accordance with service procedures used for Land Rover models.
