Purpose and Application of the BMW 868 MHz Key Fob

The presented key fob is a component of the remote control system for the central locking and vehicle start system in selected BMW models: 5 Series E60, 1 Series E87, 3 Series E90/E91, and X5 E70. Operating at a frequency of 868 MHz, it is compatible with the factory comfort modules and control units used in European versions of these cars.

Due to its classification within the switches, control elements, and ignition switches category, the key fob can be treated as a source of parts for repairing an existing key fob, completing missing housing elements, buttons, or electronics, as well as material for specialized programming work in dedicated service centers.

Technical and Constructional Characteristics

The BMW key fob in this version is structurally linked to the comfort system used in the aforementioned vehicle generations. In practice, this means:

• Integration with the factory control system – the key fob is designed to work with original BMW modules responsible for the central locking and comfort functions.
• Dedicated 868 MHz radio frequency – compliant with European standards for vehicle remote control systems.
• Construction intended for programming – the key fob's electronics can be used as a donor or base for adaptation in conjunction with appropriate diagnostic equipment.

The product has an assigned OEM part number and a set of interchangeable numbers, which facilitates verification of compatibility with a specific car configuration in BMW catalogs and professional parts selection systems.

Product Condition and Potential Service Applications

The key fob is offered in a damaged condition, meaning it is not intended for direct, trouble-free installation as a fully functional remote. However, it can serve as a valuable base for:

• Salvaging specific components – e.g., electronic parts, coils, buttons, or housing elements, if they are preserved in a usable condition,
• Refurbishment in a specialized service center – as a donor part for repairing another key fob with a compatible part number,
• Training and testing purposes – in workshops dealing with automotive electronics and key programming.

Before purchasing, it is recommended that the workshop or automotive electrician verify the possibility of using this unit for a specific application, considering its physical condition and the vehicle's requirements.

Vehicle Selection and Part Number Compatibility

To correctly select this key fob for your BMW, it is advisable to use the OEM part number and interchangeable numbers visible in the technical specifications. This allows for:

• Precise matching to a specific year and equipment version,
• Checking compatibility in BMW catalogs or professional parts selection systems,
• Minimizing the risk of purchasing an incorrect part in case of differences between markets or equipment versions.

If in doubt, it is recommended to compare the markings with your currently used key fob or consult a service specializing in BMW electronics, who can confirm the possibility of using this unit as a donor.
