Liftmaster/Chamberlain garage door openers now use Security + 2.0 as their rolling code protocol and both Lear Car2U (General Motors) and HomeLink (Nissan and just about everyone else) built in garage door buttons aren't compatible. I bought a new Chamberlain. It has the new security protocol and I couldn't program any of my cars, Nissan and GMC, I finally found out I had to buy a repeater for each protocol. Now the door works normally with all three cars.
Look to see if your Liftmaster says Security+ 2.0. If so, it won't work with current Homelink without a repeater.
