As a result, it can be used as a replacement for a factory key or as a base for transferring electronics and the key blade, according to the specific requirements of the vehicle.

The item comes from the original BMW line, which promotes proper cooperation with factory comfort and alarm modules, and also facilitates subsequent coding at a specialized service center or with an auto electrician.

Technical characteristics of the remote

This is a radio key integrated with alarm control functionality, operating in the stable 868 MHz band. This type of remote provides:

• remote control of the central locking system,
• cooperation with the factory BMW alarm,
• the possibility of matching to an existing installation after proper coding.

The housing and electronic circuit are designed to BMW specifications, which promotes proper operating range and correct communication with the vehicle after being correctly assigned to the car.

Condition and practical application

The key is used, making it an economical solution when replacing a damaged remote or expanding the set of keys for the car. In practice, it can be used as:

• a base for transferring electronics from a damaged housing,
• a donor of components for repairing an existing remote,
• a component to be coded as an additional key for the vehicle.

Due to the specifics of BMW security systems, it is recommended to perform a programming procedure at a specialized service center before installation and use to ensure full functionality and correct operation of the immobilizer and alarm.

Why choose this radio remote

The original BMW radio remote ensures better compatibility with vehicle electronics than universal replacements, which translates into stable operation of the comfort and alarm system. The factory design minimizes the risk of problems with range, interference, or communication protocol incompatibility.

An additional advantage is the ability to use existing part numbers and interchangeable numbers when verifying compatibility with a specific vehicle equipment version – this facilitates the selection of the correct remote based on BMW catalog data.
