Vehicle Application and Function

The presented set belongs to the Locks and Latches group and is dedicated to the BMW 3 Series E90/E91 models after the facelift (LCI). The component operates in the front driver's door area, responsible for the mechanical locking and unlocking of the door using the key, which serves as an important complement to the central locking system and vehicle security in emergency situations (e.g., discharged battery, electronic issues).

Set Construction and Benefits of Use

The set includes the door lock mechanism and the cylinder with a key, allowing for a cohesive replacement of the entire system responsible for key operation in the driver's door. This solution:

• simplifies installation – no need to match individual components,
• ensures uniform operation of the cylinder and locking mechanism,
• reduces the risk of jamming and malfunction when turning the key,
• allows for the restoration of comfortable door operation after damage to the factory lock.

By using an original BMW solution, proper fit to the door structure and correct cooperation with other components of the locking system are maintained.

Installation in the Front Driver's Door Area

The mechanism is intended for installation in the front part of the body, in the driver's door. The construction of the lock and cylinder is prepared for operation in the factory mounting hole, which facilitates servicing and shortens replacement time. In practice, this means that after removing the door trim and the old lock, the set can be fitted into the place of the original component, maintaining proper positioning relative to the exterior door handle.

Condition and Service Application

The component comes from the group of used BMW parts, allowing for economical repair while maintaining original construction. This type of lock set with cylinder and key is particularly useful in situations such as:

• mechanical damage to the lock after an attempted break-in,
• wear of the cylinder resulting in problems with turning the key,
• the need to replace the lock after replacing the door or bodywork repair.

For workshops and services specializing in BMW, this is a practical solution enabling efficient, technically correct repair of the driver's door area.
