Purpose and vehicle placement

The presented lock is designed for installation in the front right door (passenger side) in selected BMW F40 and G20 / G21 / G28 / G26 series models. Its placement in the front door area means the component is responsible for:

• mechanical locking and unlocking of the door leaf,
• cooperation with the external and internal door handle,
• transmitting movement to the opening mechanism,
• working with the central locking system and control via remote or from inside the vehicle.

Thanks to a design consistent with BMW factory standards, the lock maintains the correct mounting geometry and proper positioning relative to guides and hinges, which translates into stable door closing and repeatable latch operation.

Construction and technical function

The lock mechanism combines a mechanical and electrical part in one housing, creating a complete module responsible for operating the passenger-side door. In practice, this means:

• an integrated locking system working with rods and handles,
• a built-in actuator responsible for latch movement during central locking operation,
• adaptation to work with the factory electrical installation of a given BMW model,
• a design optimized for vibration and noise damping when closing the door.

The original construction ensures consistency with safety and comfort systems, such as central locking, comfort closing functions, and integration with the vehicle's body electronics.

Benefits of using an original BMW lock

Using a factory front right door lock in a BMW F40 / G20 / G21 / G28 / G26 allows you to maintain the parameters specified by the vehicle manufacturer. In practice, the user gains:

• a secure fit to the door structure and pillar,
• proper cooperation with the existing electrical harness,
• stable central locking operation without the need for modifications,
• preservation of the factory operating characteristics of handles and the latch.

The used OEM part is particularly attractive in situations where technical compatibility with the original and reducing repair costs while maintaining the quality typical of BMW solutions are the priority.

Condition, verification, and service application

The offered lock comes from a group of used parts, which in practice means it is a component from dismantling, retaining its factory design and intended for re-installation in a vehicle. This type of component is often chosen for:

• post-accident repairs of the right side of the body,
• fixing central locking faults on the passenger side,
• cases of mechanical damage to the latch or lock housing,
• services specializing in the BMW brand, where compliance with factory solutions is essential.

Thanks to the preservation of the original design, installation is carried out in a manner similar to the factory process, which facilitates workshop work and reduces the risk of fitment issues.
