Purpose and BMW Fitment

The presented lock cylinder with guide is dedicated to the front, right-hand driver's door in selected BMW F-series models, specifically F20 and F34. The element's construction complies with the manufacturer's factory standards, facilitating installation in place of the original part without the need for bodywork modifications or interference with the door structure.

Thanks to the use of original mounting geometry and a proper housing profile, the lock works with the factory handle mechanism and central locking rods, maintaining correct travel and smooth operation of the cylinder.

Color and Body Integration

The element is prepared for installation on a body painted in the color Yas Marina Blue Metallic – B68. Proper color matching ensures visual consistency with the body line, which is particularly important when replacing exterior components on premium vehicles.

Choosing the correct paint shade reduces the need for additional painting, thereby shortening repair time and minimizing the risk of color discrepancies between individual body panels.

Set Construction and Functionality

The set includes the driver's door lock cylinder guide with a matching key. This solution:

• ensures consistent operation of the mechanical door opening system,
• facilitates servicing and replacement of a damaged lock without the need to adapt the existing key,
• allows for the restoration of full manual locking and unlocking functionality for the driver's door.

The lock cylinder mechanism works with the factory door lock system, enabling direct transfer of the key's movement to the rods and the lock latch. This ensures proper response to key rotation and the appropriate force required for operation.

Condition, Origin, and Service Application

The offered element is from original BMW production and is intended as a replacement part for vehicles equipped with an external mechanical lock on the driver's side. It is suitable for standard repairs after mechanical damage as well as for replacing a worn lock that has lost its smooth operation or proper engagement.

Choosing an original component from the same model line helps reduce the risk of fitment issues, mounting play, or improper interaction with the existing door mechanism.

Benefits of Using an Original Lock Cylinder
