• secure door closure and retention in the closed position while driving,
• correct response to signals from the central locking system,
• proper cooperation with the passenger safety system in the rear seats. Thanks to its factory design, the lock maintains compatibility with the door geometry and operating parameters specified by the vehicle manufacturer.

The presented lock has been designed specifically for the rear right side of the body, which eliminates the need for modifications or adaptations. The appropriate placement of mounting points and connection sockets allows for installation in place of the factory component, while maintaining:

• correct positioning relative to the pillar and door frame,
• compatibility with original rods and handles,
• consistency with the factory vehicle locking system. Such fitment promotes stable operation of the locking mechanism and reduces the risk of leaks or improper door closing.
