BMW X3 Owners Manual: The concept
The universal garage door opener can operate up to 3 functions of remote-controlled systems such as garage door drives or lighting systems. The universal garage door opener replaces up to 3 different hand-held transmitters.
To operate the remote control, the buttons on the interior rearview mirror must be programmed with the desired functions. The hand-held transmitter for the particular system is required in order to program the remote control.
During programming
During programming and before activating a device using the universal garage door opener, ensure that there are no people, animals or objects in the area of the remote-controlled device; otherwise, there is a risk of injury or damage.
Also follow the safety instructions of the handheld transmitter.
Before selling the vehicle, delete the stored functions for the sake of security.
