super fast delivery, inredible price compared to purchasing from the big box store, programmed in 4 easy steps:turn on remote, push the remote button you are going to use 4x if your opener has a green button, fewer times for other color models,exit the remote with one of the other two buttons, push the green program button on your garage door opener itself, theaim the remote at the green button and push your dedicated remote button ( I used the long one.) until the light flashes. It didn't work the first time because I did not push the button 4 times long enough. Repeated the steps and the remote opened the garage door perfectly.Very happy with the remote, the brand name ( lift master) and the big savings on price. I could have bought 3 of these remotes for what I paid for one two years ago. You have to love Amazon. I am purchasing two more right now as back ups even though our original remotes have been in the family since 1994!!!!!!
