Vehicle Application and Placement

The presented lock mechanism is designed to operate in the front right door, in the area responsible for locking and unlocking the door leaf. Its placement in the front-right section allows for precise interaction with the handle, rods, and control system, which translates to predictable operation of the entire assembly.

Thanks to its dedicated fit for the CLA C117 body, the lock maintains the correct position relative to the pillar and striker, minimizing the risk of play, rattling, or closing issues. This is particularly important in vehicles used daily, where the repeatability of the mechanism's operation contributes to user comfort.

Lock Mechanism Construction and Function

The front right door lock mechanism in the Mercedes CLA C117 is responsible for several key functions:

• mechanical locking of the door leaf to the body,
• stable holding of the door in the closed position while driving,
• interaction with the interior and exterior opening systems,
• transferring motion from the handle and rods to the locking elements.

Its internal design ensures repeatable operation during multiple opening and closing cycles, and its factory fit with other door components minimizes wear on cooperating parts. Using an original solution allows for maintaining the correct locking bolt geometry and predictable response to handle movement.

Benefits of Using an Original Mercedes Lock

Choosing an original door lock for the Mercedes CLA C117 offers a range of practical advantages:

• Structural Compatibility – the mechanism is matched to the factory door system, facilitating installation and reducing the need for modifications.
• Integration with Locking System – the lock works with the existing control system and mechanical door components.
• Stable Operation in the Front Right Door Area – correct positioning relative to the pillar and hinges promotes quiet, predictable operation.
• User Safety – a properly functioning lock reduces the risk of accidental door opening while driving.

This type of component from the Locks and Latches group is particularly recommended when replacing a damaged or worn mechanism, especially when maintaining the door's original operating parameters is a priority.

Condition, Fitment, and Service Application

The offered lock is a used part, meaning it comes from a dismantled vehicle and has been verified for further use. This type of part is a good solution for service repairs where combining original construction with a rational replacement cost is a priority.

The mechanism is intended for use as a replacement for the factory lock in the front right door. When selecting, it is important to ensure compatibility with the specific CLA C117 body version and the door configuration of the particular vehicle to maintain the full functionality of the opening and locking system.

Correctly selecting a door lock based on the part number and vehicle configuration is crucial for the proper operation of the entire system.
