Application and function in BMW vehicles

The presented remote key is intended for selected BMW F-series models, such as the F20, F21, F22, F30, and F31, which utilize an 868 MHz remote control system. The component acts as a signal transmitter for comfort and security modules, responsible for:

• remote locking and unlocking of the vehicle,
• operation of comfort functions associated with the central locking system,
• cooperation with the ignition system or start/stop button (depending on the vehicle configuration).

For proper operation, it is necessary to match the remote to the specific vehicle electronics configuration and perform appropriate programming.

Design and integration with the electronic system

The key has been designed as an OEM BMW component, which means full compatibility with the electrical architecture and radio communication used in these models. The remote housing integrates:

• a radio module operating at 868 MHz,
• buttons for controlling the central locking,
• space for immobilizer electronics and a potential mechanical blade (depending on the version).

This solution allows for maintaining consistency with factory safety and comfort systems, and also facilitates the service replacement of a damaged remote with a component of the same specification.

Technical condition and intended use for repairs

The product is offered in for parts or not working condition, which means it should be treated as a base for repairs, regeneration, or obtaining selected components. It can be used, among other things, as:

• a donor for the housing or mechanical components,
• a source of parts for repairing another remote of the same specification,
• training or test material for workshops specializing in BMW electronics.

Before purchasing, please consider the necessity of potential repairs, programming, or transferring electronics from another functional key.

Matching by part numbers and parameters

To ensure that the offered remote key will be suitable for a specific BMW vehicle, it is necessary to verify compatibility based on the OEM part number and available interchangeable numbers. This information is crucial when selecting a component within a single model generation, where different variants of electronics and equipment exist. In case of doubt, it is recommended to compare the markings with the previously used remote or the vehicle's service documentation.

Expansion of the control system and additional materials

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

When performing service work on vehicle electronics, it is also worth ensuring a functional braking system – the article Second-hand braking system: how to safely choose discs, calipers, and ABS?, which contains a practical checklist for purchasing components from the secondary market, will help in selecting used components.
