The element belongs to the group of body control components responsible for handling functions such as locking and unlocking doors, and depending on the vehicle configuration – also controlling additional comfort functions. As an original BMW part, it is designed for proper fitment to vehicle systems and correct cooperation with comfort modules.

Technical characteristics and vehicle integration

As an element from the Switches, control elements and ignition locks category, the remote acts as an external user interface for the vehicle's locking and starting system. The housing is adapted for daily use, and the electronic system inside the key works with factory BMW control modules, using appropriate coding and operating frequency.

Due to the specifics of BMW security systems, it is recommended to work with a specialized service or automotive electrician before installing and adapting the remote to a specific vehicle. This allows for proper key coding, synchronization with the vehicle, and verification of full functionality after installation.

Product condition and service application

The product is offered in for parts or not working condition, which means it should be treated primarily as a source of parts or a base for repair and regeneration. It can be used for:

• obtaining the housing or selected mechanical elements,
• using selected electronic components after verification,
• training and diagnostic purposes in workshops dealing with BMW electronics.

Before planned use in a vehicle, thorough diagnostics and assessment of the suitability of individual elements by a specialist are necessary. This approach allows for reducing service costs while maintaining control over the safety and reliability of the system.

Part number matching and identification

The key has a dedicated OEM part number and associated interchangeable numbers, which facilitates its identification in BMW catalogs and service systems. Thanks to this, it is possible to precisely verify compatibility with a specific vehicle equipment version and production year. In practice, this means the possibility of conscious selection of the element for repair, regeneration, or obtaining component parts.

If you are planning a comprehensive repair or upgrade of the control and security zone in your BMW and need other elements from the same group, such as remotes, ignition locks, or control modules, check the available parts in the BMW Switches, control elements and ignition locks category.
