Purpose and function of the BMW 868 MHz key

The presented remote key is dedicated to BMW F20, F21, F22, F30, F31, and F32 platforms, which are popular F-generation 1, 2, and 3 series models. As an element of the comfort access and control system, it is responsible for remote locking and unlocking of the vehicle, and depending on the car's configuration – also for operating additional functions provided by the manufacturer.

By operating at a frequency of 868 MHz, the remote control works with factory comfort modules used in European versions of BMW, which facilitates matching it to the specific vehicle configuration in terms of electronics and software.

Technical characteristics and control group

The key belongs to the Switches, control elements and ignition locks group, i.e., components responsible for handling control functions in the vehicle. In the case of this remote, this primarily includes:

• handling remote locking and unlocking of doors,
• integration with the ignition system or keyless entry system,
• cooperation with vehicle electronics regarding start authorization.

Due to the specificity of BMW security systems, the key requires proper matching and programming to a specific vehicle, performed by a specialized service or automotive electronics technician.

Product condition and service application

The item is offered in for parts or not working condition, which means it is treated as a parts base – to be used for service, repair purposes, or as a donor for the housing, buttons, or selected electronic components. It is not a complete, ready-to-use plug-and-play solution and requires verification and potential regeneration before installation.

This product condition makes it an attractive option for workshops specializing in BMW electronics that are looking for original components to repair existing keys, restore damaged elements, or build test sets.

Matching by numbers and support with selection

The key has an OEM part number and associated interchangeable numbers, which allows for precise identification in BMW catalogs and minimizes the risk of selecting an incorrect remote for a specific model. When purchasing, it is worth comparing the markings with your existing element or the vehicle's service documentation.
