The HBW1573 remotes were made with different brand names and product model numbers. They were sold as one or three button remotes using a purple learn button to program the remotes. To replace the original discontinued models from the manufacturer we now use the compatible HBW1573 Liftmaster models.
HBW1573 is the correct remote to order when you have HBW1573 printed on the back of your old remote.
Order a one button remote if your will be using it on a single residential garage door opener or a single commercial door/gate operator.
Order a three button remote if your will be using it on multiple residential garage door openers or commercial door/gate operators using the same HBW1573 remotes.
