Purpose and function of the tailgate lock

The offered lock cylinder operates in the rear zone of the vehicle body, responsible for the mechanical operation of the trunk lid. A properly selected component ensures:

• stable locking of the trunk lid in the closed position,
• repeatable, predictable operation of the mechanism with every opening and closing,
• maintenance of the correct operating geometry of the handle and linkages in the rear part of the vehicle.

Thanks to this, the tailgate remains securely closed even during intensive use, and access to the luggage compartment is convenient and predictable.

Benefits of using an original lock cylinder

The tailgate lock cylinder has been designed as a component meeting the manufacturer's factory standards. Using such a component allows for maintaining:

• proper fit to the mounting points in the rear part of the body,
• consistency of operation with the existing tailgate and locking mechanism,
• appropriate operating quality during daily vehicle use.

This is particularly important for vehicles where the trunk lid is used frequently – the correct lock reduces the risk of play, closing problems, and unwanted noises while driving.

Characteristics of the used component

The presented lock is a used component, which in practice means it comes from disassembly and has been verified for suitability for further use. This type of part represents a reasonable compromise between the cost of repair and maintaining the appropriate quality of the tailgate mechanism operation. A used component allows for restoring full functionality to the rear body zone without the need to invest in a new subassembly.

Installation in the rear part of the vehicle

The tailgate lock cylinder is intended for installation in the rear area of the vehicle, in the immediate vicinity of the trunk lid locking mechanism. During replacement, it is recommended to:

• check the condition of the linkages and levers working with the cylinder,
• inspect the alignment of the tailgate relative to the body after installation,
• perform multiple test openings and closings to verify smooth operation.

Such an approach allows for achieving a stable service result and limits the need for re-adjustment in the future.
