Purpose and function in the control system

The presented key fob with a radio button is a component designed to work with the factory remote control system in Mini models, particularly the R50 series. It is responsible for the convenient triggering of central locking, alarm functions, and – depending on the vehicle configuration – integration with the radio system and comfort module.

The item belongs to the Switches, control elements and ignition locks group, which means it is part of the electronic control circuit rather than a classic mechanical vehicle component. In practice, it affects daily vehicle operation, user comfort, and anti-theft security.

Construction and performance parameters

The key fob is equipped with an integrated remote control button operating at a frequency of 433 MHz, used in Mini radio systems. This configuration enables communication with the appropriate body control module, ensuring correct signal recognition and the execution of programmed functions.

The solution combines the function of a mechanical key and an electronic transmitter in one housing, which reduces the number of separate items in daily use. As a result, the user has quick access to basic vehicle functions with a single, compact device.

Integration with vehicle electronics

As an OEM Mini component, the key fob is designed to work with factory control modules, which helps maintain the consistency of the electrical installation and the logical configuration of the comfort system. Proper matching to a specific vehicle model and year, however, requires verification of compatibility and the appropriate programming procedure in the vehicle.

The product has an assigned part number and associated interchangeable numbers, which facilitates identification in service catalogs and the selection of a suitable replacement within the same family of components. For proper operation, it is necessary to synchronize it with the existing body control module and – depending on the configuration – add it to the immobilizer system.

Service application and condition

The item is offered in a condition described as damaged / for parts, making it suitable primarily as a donor for components, housing, or buttons for other keys during the repair process. It may be useful in workshops specializing in automotive electronics, key duplication, and remote control regeneration.

Due to the declared condition, detailed electronics diagnostics and verification of the suitability of individual elements are recommended before planned use. This approach allows for the optimization of repair costs by using functional components from disassembly instead of investing in a completely new set.

Expansion of the control system in Mini

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