I have a 1995 540i with a 3 button remote. I have not found many explanations on how to pair this remote to the car. It is not the separate key fob, the buttons are built into the key that turns the ignition. The power locks do work, just not remotely. I have changed the battery and the red LED does flash when any of the 3 buttons are pressed. The 3 buttons I have on my remote are a large bmw roundel, a small house, and a wifi logo. I have not seen this key anywhere else and was wondering if anyone had before, it is the same dimensions as the normal e34 key that has the trunk pop for the 3rd button. Any help would be appreciated.
