I bought this as a remote for my car since I just leased a house with a 2 car garage with some friends. The owner/retailer handed us one remote and I let my roommate take that one while I went on the search for one. I checked the motor for the garage and it was a Liftmaster with a green sync button. Bought this when I found it was compatible with green sync button Liftmasters. It came with instructions how to sync it and within 3 minutes of opening the box we had 2 garage openers for our garage. Very pleased.
