Homelink on My X5 communicates with my 1987 garage door opener, where can I find a "hand held" remote that can do the same? I have tried four remotes and none of them work, my 2002 X5 can do it, so is there a remote that can do the same? You know learning the code. My garage door opener has 9 pins, but obviously my X5 didn't care for them.

Any ideas?
