Application and function of the remote

The BMW alarm key remote in the 868 MHz version is responsible for the wireless operation of the central locking, alarm, and – depending on the vehicle configuration – additional comfort functions. It is a component integrated with the vehicle's electronics, working with the factory immobilizer and comfort modules, which allows for maintaining the consistency of the entire security system.

As a part from the Switches, controls and ignition locks group, the remote acts as an external user interface – it enables quick and convenient control of locks and the alarm without the need to use a traditional ignition lock for every operation.

Compatibility and technical markings

The presented remote is intended for selected BMW models, including the X3 series and F series, where an 868 MHz radio system is used. The original OEM part number and associated interchangeable numbers allow for precise identification of the component in the manufacturer's catalogs and facilitate the selection of the correct element for a specific equipment version.

Due to the fact that the part has many reference numbers, it can be used as a replacement in various factory configurations, which increases flexibility during repairs and upgrades of the locking and alarm control system.

Product condition and installation recommendations

The condition defined as for parts or not working means that the remote is intended primarily as a donor of components or a base for repair and regeneration. It can be used to obtain the housing, buttons, electronic parts, or as training and testing material for services specializing in BMW automotive electronics.

Before the planned installation in the vehicle, detailed diagnostics and possible repair and programming in a specialized service are recommended. In the case of immobilizer and alarm systems, it is necessary to register the remote to a specific car using appropriate diagnostic tools to ensure proper cooperation with the control modules.

Benefits of using an original BMW remote

Choosing an original BMW remote from the control and ignition lock group ensures:

• consistency with the factory security and comfort system,
• appropriate radio parameters matched to the 868 MHz installation,
• the possibility of using components in the professional regeneration process,
• easier identification in catalogs thanks to assigned OEM and reference numbers.

For workshops and automotive electricians, such a remote is a valuable source of components, allowing for the economical repair of other units used in the same BMW models.

If you are planning a comprehensive repair or upgrade of the locking and ignition control zone in your BMW and need other elements from the same group, such as control modules, ignition lock inserts, or start-stop buttons, check the available parts in the BMW Switches, controls and ignition locks category.

Safety and selection of used components

When working with vehicle security systems – including remotes, controllers, and comfort modules – it is crucial to follow safety procedures and make an informed selection of used components. It is worth paying attention to the condition of the electronics, the possibility of reprogramming, and compatibility with the specific vehicle equipment version.
