Is this the correct keypad for a Chamberlain Liftmaster Professional 1/3 hp p/n 41A5483-10 made in 01/05 with a red learn button?

I have Chamberlain 1/3hp 41A4252-7A and 2nd door was 1/2hp unit same year of (1994) that both connected easy and in less than minute. Think mine was green learn light, but directions for red or green learn button were noted. So can't say for sure, but don't see why your newer 2005 model wouldn't work. Now I see this was 7 month old post so you probably already resolved one way or another. Either way, answer is posted for someone else :-)

Hello, and thank you for your question, Yes, this is the correct keypad for a LiftMaster opener with a red learn button.
