Control remoto Liftmaster 893max

That depends on your set up. If you have a receiver with more than 1 channel (like the 850LM) you can set one channel to open and one to close, then program one button of the remote to open and another to close. Alternatively, you can set your opener to close automatically which means you will press the remote to open and the gate/door will close on its own.

If you want to override a specific button, you can, regardless of which remote you use. Follow the vehicle instruction manual for programming tips. Often times people will delete all programmed information before proceeding to program a new remote by pressing the outer 2 buttons for 30-60 seconds

Hello Marc. If you go back to the item on our site and scroll to the bottom, there's a video that shows how to program this remote :)

Hi Connie. We have added a video on how to change the battery. Please go back to the item in question to see the instructional video.
