This is almost exactly like the one I replaced. I was concerned it would be complicated to program but it worked immediately!Took less than 10 minutes to install completely. Simple instructions, I like the results.It worked like it was supposed to!Spent a lot of time trying to program it. Tried everything. I was parring brand new garage opener. It was not possible to get it working. At the end I bought one from Home Depot and it worked with one programming sequence.Easy to install but code randomly stopped working. Not reliable as an emergency if you forget your key.Easy to install.This generic brand wireless keypad was advertised to work with my Genie Garage Door Opener. I couldn't get it to sync up with the door opener, so I called Genie to see if I was doing something wrong. So after 30 minutes of trouble shooting, and no progress, I decided to go to Lowes and buy a Genie brand wireless keypad and it worked right away.The aaa batteries they send barely fit in housing, loose connection on battery contacts... do not recommend!
