The Homelink website shows that Liftmaster is compatible.<font face="Verdana, Arial" size="2">Originally posted by rickse:
Liftmaster is the name of the garage door opener that I own. It has a variable code, which means that it changes upon each use. This means also that the car needs to be programmed from the garage opener iteself, rather than just from the remote door opener.
What I did was press the two outside Homelink buttons for about 20 seconds to clear the existing information (the red light starts to flash). I then went to the garage door opener and pressed the "learn" button on the opener until the indicator light went on. I then pressed the left Homelink button for 5 seconds each three times. I also tried a number of different iterations of pressing the Homelink buttons (20 seconds at a time, 10 seconds at a time, pressing Homelink before the "learn" button, after the "learn" button). I also tried the center and right Homelink buttons to see if that might help.
This was tried on two different Odysseys, since a friend was over and couldn't get his to work either!!

You left out a step in your programming. Once you've cleared the codes (...holding the outside buttons for about 20 secs), you've got to hold the remote for your liftmaster within the 2-5 inches and press the button on the remote and the button that you want to program on the Homelink console at the same time (hold both buttons for about 2 seconds). Then you teach the Homelink system the rolling code just as you described.</font>
