Vehicle Application and Placement

The presented lock cylinder is specifically designed for the Audi S4 B9 generation and is installed on the front right door. Its placement on the driver's side allows for direct key operation, which is particularly important in emergency situations, with a discharged battery, or when the central locking system malfunctions.

The component works in conjunction with the factory door locking mechanism, ensuring proper transfer of the key's movement to the lock's mechanics. This allows for maintaining consistency with other elements of the vehicle's body security system.

Technical and Functional Characteristics

The Audi S4 B9 driver's door lock cylinder is part of the system responsible for the vehicle's mechanical security. The design includes:

• precise key guidance in the cylinder's keyhole,
• a stable connection to the door locking mechanism,
• proper fit with the door panel and external door handle,
• maintenance of the original mounting geometry.

By using an original Audi solution, the lock maintains correct mounting tolerances, reducing the risk of play, jamming, or improper door closure. This is particularly important in S4-class vehicles, where precise operation of all body components is expected.

Application of the Original Lock and Benefits of Installation

Choosing an original lock cylinder from the Locks and Latches category helps maintain the structural integrity of the door and avoids problems typical of aftermarket replacements. Installing such a component offers several benefits:

• maintaining the original fit for the Audi S4 B9 door,
• proper cooperation with the existing locking mechanism,
• reducing the risk of leaks and improper closure,
• preserving the original functionality of the driver's side keyhole.

A used door lock is a sensible choice for drivers who want to restore the security system's functionality at a controlled cost, while maintaining the vehicle's original specifications.

Component Condition and Installation Aspects

The offered lock cylinder is a used part, meaning it has been removed from a dismantled vehicle and verified for its suitability for further use. This type of part is particularly attractive to users seeking a balance between quality and repair cost, while preserving the original Audi construction.

Due to its original origin, installation is similar to the service procedure intended by the manufacturer. Once correctly seated in the door and connected to the locking mechanism, the lock should provide stable operation and repeatable performance with every key turn.

Selecting the Right Locks and Additional Information

When selecting a lock cylinder for the Audi S4 B9, it's important to consider compatibility with the specific body version and installation side. Manufacturer markings, part numbers, and interchangeable numbers can be helpful for precise identification of the correct component within the same model generation.
