Lock Purpose and Function

The presented door lock is dedicated for installation in the rear right part of the vehicle, ensuring full compatibility with the factory body structure. It is responsible for the mechanical locking of the door and cooperation with the actuator and the Keyless Go system, which translates to comfortable vehicle operation without the need to use a traditional key.

This element integrates the functions of a latch and an actuator, allowing for efficient control of the lock from the remote control, external door handle, and internal central locking buttons. By maintaining the original geometry and mounting points, installation is predictable and repeatable.

Keyless Go System Compatibility

A key feature of this lock is its adaptation for use with the Keyless Go system, which requires precise cooperation between mechanical and electrical components. The lock is designed to respond correctly to signals from the comfort modules, enabling:

• automatic unlocking of doors when approaching the vehicle with the key,
• secure locking after moving away from the car or using a button,
• stable cooperation with the central locking and anti-theft systems.

This ensures full functionality of the keyless system, and vehicle operation remains intuitive and convenient.

Technical Characteristics and Installation

As a part from the Locks and Latches category, the rear right door lock has been designed for a specific body model, minimizing the risk of fitting issues. Its placement on the vehicle in the rear right part of the body allows for unambiguous identification of the mounting position and reduces the possibility of errors in part selection.

The product is intended for direct installation in place of the factory lock, using original mounting points and existing wiring. With proper installation, the door closing geometry, correct closing force, and proper cooperation with handles and seals are maintained.

Condition and Benefits of Using a Used Part

The offered lock is a used part, allowing for economical vehicle repair while maintaining the original manufacturer's specifications. Choosing such a part is a good solution when you want to preserve the factory lock design and compatibility with the existing comfort and security system.

By using an original door lock, you reduce the risk of fitting problems, incorrect actuator operation, or communication errors with the comfort module. This is a practical solution for both post-accident repairs and for replacing worn or damaged locking system components.
