Vehicle Application and Function

The presented lock mechanism is dedicated to the rear right side of the body, ensuring a proper fit with the passenger door structure of the Seat Altea XL model. Its placement on the vehicle is factory-defined, allowing the lock to cooperate with guides, hinges, and the electrical harness in accordance with the manufacturer's design.

As the component responsible for locking, the lock integrates both mechanical parts and an actuator within a single housing, enabling:

• stable closing and holding the door in the locked position,
• smooth unlocking via remote control or central locking system,
• proper cooperation with the external and internal door handles.

Benefits of Using an Original Lock

Using an original door lock for the Seat model ensures correct fitment with the door structure and predictable operation in daily use. This component from the Doors and Door Panels group has been designed for the specific body geometry of the Altea XL, reducing the risk of play, leaks, or closing issues.

Key advantages include:

• dedicated vehicle placement – the lock is prepared for operation on the rear right side of the body,
• maintenance of the factory-designed safety and user comfort concept,
• ability to restore correct central locking operation without modifying the electrical system.

Installation Characteristics

The lock mechanism has been developed as a component to be installed within the inner structure of the door, in the area of the jamb to the body pillar. This allows for stable closing and repeatable latch operation after correct mounting and adjustment. The design intended for the specific Seat model facilitates service installation and reduces the need for additional modifications.

The vehicle placement designated as Rear – Right Side clearly identifies which door this component is intended for, minimizing the risk of errors when selecting parts.

Condition and Service Application

The offered door lock is from the used parts group, making it a sensible choice for operational repairs where functionality and compliance with the original structure are prioritized. This type of component is suitable for both replacing a damaged lock and diagnosing central locking issues on the rear right side.
