1 Radio technology
Radio technology is a comprehensive term covering all areas of cordless telecommunication such as telephone,
radio, television. Transmission is by means of electromagnetic waves.
Due to the fact that the radio waves are not limited to one single direction and have a wider range than the infrared
waves, this technology is also being increasingly employed in remote controls.
The same remote-control technology is used in motor vehicle construction as, for example, in construction site
cranes, in model construction, alarm systems, garage-door opening systems etc.
These remote controls are operated on the same approved frequency (315 MHz or 433.92 MHz).
2 Radio remote control, general information
The radio remote control for the central locking system (FZV) is a further development of the radio-compact remote
control, or the radio remote control which first appeared in the E38.
The radio transmitter is still located in the grip of the car key, the receiver module is installed in the vehicle. All radio
telegrams are encoded by means of a constantly changing code. This ensures that the vehicle cannot be opened by
someone who has eavesdropped telegrams.
Depending on vehicle type, equipment and country-specific version, in addition to the functions "opening/closing
central locking system" and "central arrest" the following functions are also available: "activating/deactivating alarm
system", "deactivating tilt sensor/passenger-compartment sensor", "convenient opening/closing window and sliding
roof", "switching on interior lighting" and "opening/closing luggage compartment lid".
The remote control keys can be initialized at the vehicle without visiting a BMW Service point when, for example, the
owner requires additional keys or, for security reasons, following the loss of a radio remote control key. The
initialization procedure is described in the respective Owner's Handbooks.
The radio remote control is available as standard equipment in the models E38, E39, E46 and as an option in the
E36 models (option 302).
Up to 4 radio transmitters can be operated per vehicle.
In many countries, radio remote controls are subject to radio-technical registration specifications. The required
designation is on the key grip.
