Purpose and function of the component

The lock cylinder base is structurally matched to the front right door of the BMW X3 E83 and is responsible for the proper positioning of the cylinder and its stable mounting in the door panel. This ensures that the lock operates smoothly and that the forces exerted during opening and closing are evenly distributed across the door components.

Its placement in the front passenger door area allows for consistency with the factory lock geometry, which is important for both user comfort and the durability of the entire mechanism.

Construction and fitment for BMW X3 E83

The component has been designed as part of the BMW door lock system, maintaining appropriate assembly tolerances and a shape that interfaces with the door panel and lock cylinder. The proper geometry of the base reduces operating play and minimizes the risk of cylinder misalignment, which helps maintain consistent operation of the key and locking mechanism.

The product comes from the Doors and door panels group, making it structurally consistent with other elements of this body zone, such as hinges, locks, guides, or reinforcements.

Performance characteristics and installation

The base is designed for installation in factory mounting points, which facilitates service work and eliminates the need for additional modifications. The appropriately selected weight of the component promotes cylinder stability without placing excessive load on the door structure.

As a used part, the component retains the functionality necessary for continued operation, providing a reasonable solution for accident repairs, replacing a damaged lock, or restoring full door functionality after bodywork.

Application in repairs and upgrades

The lock cylinder base is suitable for both standard replacement of a damaged part and comprehensive door reconstruction after a collision. It allows for restoring the correct fitment of the lock with the panel, which is significant for sealing, acoustics, and the daily comfort of using the vehicle.

Choosing an original solution dedicated to the BMW X3 E83 reduces the risk of assembly problems, improper door closing, or excessive wear of the lock mechanism in the long term.
